However, there may be limitations on the distance over which fipronil treatment can affect subterranean termite colonies. Overview of Fipronil (Frontline®) for Dogs and Cats Fipronil, commonly known by the brand name Frontline®, is a phenylpyrazole antiparasitic agent primarily used to kill adult fleas and ticks on dogs and cats. In contrast, the untreated colonies were much more likely to be redetected, with 60% of the colonies found again after the 90-d sampling period. In both cases, there was a clear effect of insecticide treatment on colonies; all of the structures were termite free within 90 d, and 20 of the 23 treated colonies disappeared from the study areas altogether, probably because they were eliminated.

Stedfast can control termite infestation successfully without poisoning the land permanently. Three of the eight structures were each infested by two colonies, whereas the other five structures were attacked by lone colonies. Containing 5g/kg of Fipronil, used for the control of termites and nuisance ants in situations. Over the past dozen years or so, nonrepellent liquid insecticides with delayed toxicity have come to dominate the postconstruction termiticide market in most regions of the United States due to their high efficacy and low rates of treatment failures (Anon… Manzoor wide range of agricultural crops. Warriner Fipronil termite treatment. With a projected kill rate of up to 95% of ants and roaches within just 3 to 5 days, Fipronil gives insect Gray larger circles and enclosed shapes represent colonies. It can be used in low doses to cause a minimum harm to the environment. Stedfast suits pre and post construction termite treatments and can be applied at a rate of 4-8 litres per sq. It can be easily used in combination with other insecticides for effective results. Riegel Oxford University Press is a department of the University of Oxford. It works by interfering with the brain and spinal cord of insects, resulting in death. Samples were considered to belong to the same colony if they shared all the same genotypes, and they did not differ significantly (P > 0.05) in genotype frequencies. Here, we use similar methods to determine the colony-level effects of fipronil treatment (Termidor) on subterranean termites infesting houses in North Carolina. 2009, Mulrooney and Gerard 2009), well above the 60 ppm rate of application. 2003, Shelton and Grace 2003, Rust and Saran 2006, Tsunoda 2006, Haagsma and Rust 2007, Saran and Rust 2007, Spomer et al. Other termiticides are often labelled blue, yellow or red and are more toxic. Juba Stedfast Termite Chemical – UPDATED 2020 – BASF Stedfast Termiticide, Stedfast Termite Chemical Review – UPDATED 2020. Sherwood Chemicals Australia Pty Ltd. Level 3, 1060 Hay Street, West Perth 6005 Australia. Studies have shown that once individual termites contact treated soil, they can move away from the treated area covering a distance of up to 2 m (Ripa et al. BASF has introduced an effective, affordable, long-lasting termite control solution to help pest control professionals and homeowners deal with termite infestations and safeguard properties against future infestations. , Reference Huang, Lei and Xue 2006 ). This paper is dedicated to the memory of Vincent Parman, who initiated this project and conducted most of the field and laboratory work presented here. In total, we detected 128 colonies present on the eight properties at the time of treatment, including those infesting the structures. Stedfast is a green-labeled termiticide which means it belongs to the safest category of chemicals. Termite Control, “Which is better for termite control in Phoenix Arizona – Termidor or Premise?”. For best results, apply about 4 gallons (15 L) of Termidor for every 10 feet (3.0 m) of the length of your trench. 15 ml / litre of water for post-construction anti termite treatment. This diluted mixture can be sprayed or applied to the soil or wood to create a barrier that prevents any infestation while killing any termites that pass through the treated areas. S. ACTIVE CONSTITUENT: 100 g/L FIPRONIL For the protection of structures from subterranean termite damage and for the control of subterranean termites, ants, domestic cockroaches, earwigs, houseflies, web-spinning spiders, daddy-long-legs spiders, millipedes, pill bugs, and house crickets around domestic We extracted DNA from whole termite bodies by using the Gentra PureGene kit (Gentra Systems, Inc., Minneapolis, MN) or the DNeasy kit (QIAGEN, Valencia, CA). This Phenylpyrazole family insecticide packs a powerful punch, with a projected kill rate of up to 95% of ants and roaches within just 3 to 5 days. We used the PCR conditions described by Vargo (2000) and Dronnet et al. In laboratory bioassays, M. gilvus showed no preference for doses of 0–64 ppm fipronil, or for doses of 0–250 ppm imidacloprid, indicating no repellence. In addition, termite activity close to the foundation walls dramatically decreased in the case of imidacloprid and ceased altogether in the case of fipronil. I did my research and all indications directed that it is safe for pets and children. Kamble Using molecular markers to track colonies in the field with both fipronil in the current study and imidacloprid in our previous study (Parman and Vargo 2010), we have shown that at least these two nonrepellent liquid termiticides can have strong colony-level effects on subterranean termites very similar to the effects of baits, severely suppressing colony populations and in many cases resulting in their elimination. It not only kills the termites but also acts as a deadly barrier, thus blocking the progression of the termites. Dronnet IMPORTANT: READ THOROUGHLY BEFORE OPENING OR USING THIS PRODUCT. 2003). It's active ingredient fipronil, however, is quite toxic to humans and animals as well as the termites. We are grateful to S. Taylor and W. Keith (both Capital Pest Services), J. Lynn (Surety Exterminating Company), and D. Harris (Economy Exterminators) for locating and treating the study houses. The redetection rate of 60% of the untreated colonies in the current study was slightly lower than the 71% found in an earlier similar study we conducted using the same methods and in the same geographic region to evaluate the colony-level effects of imidacloprid (Parman and Vargo 2010). It is highly toxic to termites, with a lethal dose50 for the western subterranean termite, Reticulitermes hesperus Banks, of 0.2 ng per termite at 7 d (Saran and Rust 2007) and 1.33–1.39 ng per termite at 72 h for the Formosan subterranean termite, Coptotermes formosanus Shiraki (Ibrahim et al. Casida 1993). All 11 of the treated colonies—the colonies known to be infesting structures and were targeted by termiticide application—went undetected within 90 d of treatment and were not detected again during the 3-yr study period. Samples of any termites encountered were collected and held in vials containing 95% ethanol at −20°C until DNA extraction. 2009), raising the possibility that fipronil treatments can affect entire colonies of subterranean termites. During the period between 90 d after treatment and the 1-yr mark, monitors were checked at least six times and natural areas at least twice. To gauge overall termite activity throughout the study period, we tallied the number of monitors with termites present for each property at the following time points: day of treatment (before termiticide application), ≈90 d after treatment, and ≈1, 2, and 3 yr after treatment. 1 and 2). It is undetectable and non-repellent and works through ‘transfer effect’ which means affected termites transfer the chemical to other termites to eliminate an entire infestation in a short time. Mulrooney Search for other works by this author on: Colony dynamics of the Formosan subterranean termite in a frequently disturbed urban landscape, Termite business keeps growing, pp. Austin In veterinary situations, fipronil products are used as spray-on or concentrated spot-on formulations to control fleas and ticks on cats and dogs. The recommended dosage for Fipronil is 275ml per 100 litres of water. M. F. A.-G. Termidor will protect your home and eliminate almost any termite problem in less than 90 days, and up to 10 years as an in-ground termite barrier. Under heavy termite activity Termidor at every location, provided 100% effective termite protection. . Fipronil is used by the APLC but impacts to non-target insects were unknown. Locations and observed foraging areas of R. flavipes colonies on property HI before treatment and at four time points after treatment. Over the past dozen years or so, nonrepellent liquid insecticides with delayed toxicity have come to dominate the postconstruction termiticide market in most regions of the United States due to their high efficacy and low rates of treatment failures (Anonymous 2002, Potter 2004). In a study very similar to the present investigation but involving imidacloprid, we also found decreased activity of the inner monitors, although activity remained in some of those monitors throughout the 2-yr duration of the previous study (Parman and Vargo 2010). Our results provide strong evidence for potent colony wide effects of fipronil on subterranean termites leading to colony suppression and likely colony elimination under field conditions. Termidor is a very effective termite killer and works well when used outdoors to kill termites and stop them from getting into your home. . Black arrows indicate colonies present before treatment and redetected again at the later time points. This data will be updated every 24 hours. Effects were worst on (red kandosol) which supported more termite and ant species. Few of the 12 likely treated colonies were found during this period, although three (25%) were found repeatedly up to the end of the study. Stedfast is a suspension concentrate used to treat soil to get rid of subterranean termites feeding on wood. 1 litre of the concentrate diluted in 100 litres of water can provide up to 5 years of termite protection while 2 litres per 100 litres can keep your property safe from infestation for up to 10 years. NON-REPELLANT – These are the new generation of termiticides that are not detected by termites, which travel through the treated zone, become contaminated but keep travelling for a while and thereby … The National Pesticide Information Center based at Oregon State University states that the pesticide Fipronil is used to control common pests such as termites, beetles, fleas, cockroaches, ticks, fleas, and other insects. Fipronil can be used as an effective termite control as well as preventative treatment. Similarly, Ripa et al. Fipronil, in particular, is a widely used ingredient in many pest control products that include grass treatments, gel baits, spot-on pet care products, termite control products, and agricultural products. Fipronil was first registered for use in the United States in 1996. The difference among treatments was due to the high detection frequency of the untreated colonies compared with the other two groups (P < 0.001 and P < 0.03 for treated and likely treated colonies, respectively; Fisher exact test), whereas there was no significant difference between the treated and likely treated colonies during this period (P > 0.10). BASF Stedfast Termiticide – What You Should Know. It could be that although many workers in most of these likely treated colonies contacted the nearby treated soil, few or no workers in other likely treated colonies entered the treatment zone despite being active very close to it, thereby limiting the effects of the active ingredient on some colonies. Our approach of using intensive sampling and genetic fingerprinting is a powerful means to track individual colonies, but like any method to determine the fate of colonies under field conditions, it has certain limitations in definitively proving colony elimination. In brief, monitors were 30 cm long with two pieces of 20-cm-long pine wood strips inside. Mean number (±SE) of subterranean termite colonies found in mud tubes on the structure, in monitors located within 0.5 m from the foundation wall (inner monitors), and in monitors located further from the structures (2–20 m from the foundation wall; outer monitors) before treatment and at four time points after treatment. Comparisons of Efficiency of Two Formulations of Verbenone (4, 6, 6-trimethylbicyclo [3.1.1] hept-3-en-2-one) for Protecting Whitebark Pine, Combined Effects of Methoprene and Metformin on Reproduction, Longevity, and Stress Resistance in, Methods for Testing Repellents Against Bed Bugs (Hemiptera: Cimicidae), Behavioral Asymmetries Affecting Male Mating Success in, About the Entomological Society of America, Receive exclusive offers and updates from Oxford Academic, Copyright © 2021 Entomological Society of America. J. Jordon, J. Carlson, T. Juba, and P. Labadie provided valuable assistance in the field and laboratory. Shelton and Grace (17) in a simple donor-recipient test exposed C. formosanus workers to sand treated with fipronil at 1, 10, and 100 ppm for 1 h. Mean mortalities of termite donors after 14 d were 36, 36, and 98%, respectively. Our results showed the likely elimination of up to nine of 12 treated Reticulitermes spp. Also shown are the numbers of colonies in each category detected again at least once between 90-d posttreatment and 3 yr after treatment. In this review, we take a closer look at Stedfast Termite chemical and learn more about its effects and usage to help you understand what you can expect from this product. And, because Fipronil is a non-repellent, undetectable to termites, the pests freely forage through treated areas, unknowingly ingesting, picking up and transferring Fipronil throughout the population. R. W. C. Fipronil is another effective chemical treatment for termite infestation. It was placed on the market in 1993. However, your soil may not accept this much pesticide, so you can apply less if necessary. All of the colonies tracked for at least 1 yr after baiting—34 R. flavipes colonies and one R. virginicus colony—disappeared from the study and were presumed to be eliminated. We also checked other areas in the yard containing wood debris, stumps, wood piles, and other materials at least twice before treatment. Results concerning the strength of transfer and effects on recipients vary depending on the route of exposure of donor termites, temperature (Spomer et al. 2008, Bagnères et al. Cole 2). The outer ring of monitors was located ≈6 m outside of the inner ring, and in some cases, a third ring of monitors ≈6 m beyond the second ring was also installed. Subterranean termite activity at monitors (mean percent ± SE) located within 0.5 m from the foundation wall (inner monitors) and those further from the structures (2–20 m from the foundation wall; outer monitors) before treatment and at four time points after treatment. F. Five houses received a full treatment following the instructions for postconstruction conventional termite treatment in which a continuous barrier of termiticide is applied to the interior and exterior perimeters, whereas three houses received the postconstruction exterior/localized interior structural termite treatment receiving a continuous exterior barrier with interior treatment around areas showing termite activity (Table 1). Fipronil products are currently popular, because of their high toxicity to termites and other insects, their persistence and easy application. Lab study showed that it is a neonicotinoid and belongs to a neurotoxic class of pesticides. This possibility is supported by the higher across the board effects of fipronil on treated and likely treated colonies (100 and 75% disappearance, respectively, compared with 75 and 23% with imidacloprid), suggesting that the fipronil treatment in the current study affected all classes of colonies to a greater extent than did imidacloprid in our previous study (Parman and Vargo 2010). It is quite easy to use and versatile and can be mixed with the instructed amount of water before using. What a Consumer Should Know About Termidor or Fipronil. Fipronil is an active ingredient in a number of popular pest control products and it is one active ingredient that we can safely say was a game-changer for the pest control industry due to how quickly and efficiently it could get rid of target pests, namely ants, termites, and roaches. From the pesky bed bugs, fleas, ants, mosquitoes, and more, our methods will help you get rid of the pests without breaking the bank. It contains the active ingredient alphacypermethrin which is an environment friendly pyrethroid safe to use around plants. 2008), the ratio of recipients to donor (Spomer et al. The maximal distance from the house and therefore the treatment zone in these four colonies ranged from 6 to 13.5 m. As noted, all active workers from these colonies disappeared by 90 d after treatment, indicating that at least in some cases, field applications of fipronil can affect foragers located >10 m from the treatment zone. 1F2F3–4 and) and in the natural areas throughout the study (Figs. Fipronil is used to control ants, beetles, cockroaches, fleas, ticks, termites, mole crickets, thrips, rootworms, weevils, and other insects. We selected eight residential, stand-alone houses with active termite infestations in and around Wake County, NC. Traditionally, the goal of such a treatment is to create a continuous chemical barrier that excludes termites in the ground from entering a building. 3 In another study with beagles, changes in body weights were seen. As we noted in our previous studies of colony level effects of baiting (Vargo 2003) and liquid application of imidacloprid (Parman and Vargo 2010), our ability to detect the continuing presence of a colony depends on collecting samples of individuals from that colony in wood debris and monitors. FIPRONIL 50SC kills the termites in a few days and by cascade effect, eliminates the entire colony. imidacloprid and fipronil). Stedfast is one of the leading pesticide products from BASF today and serves as an effective pre-construction soil and wood treatment termiticide that delivers peace of mind to homeowners. At 50 and 100 ppm fipronil, termites tunneled only a mean of 87 +/- 0.21 and 47 +/- 0.18% deep into 50-mm treated soil, respectively, before death. Dosage 7.5 mg/kg; spray on body once and repeat in 30 days. We checked the monitors monthly for the presence of termites a mean of 7.1 ± 2.3 times over a period of 6.3 ± 1.1 mo (range, 4.9–7.9 mo) before treatment. New and new products are being introduced every day in the pest control industry to provide options for effective termite control. We installed monitors around the structures and in the yard areas between 26 April 2001 and 9 April 2002. In our view, the most likely explanation for our failure to redetect any treated colonies during the intensive 3-yr monitoring period is that they were eliminated, although we cannot exclude the possibility that some of the treated colonies persisted after treatment with greatly reduced population sizes and were not encountered again. Ibrahim It is also effective against ant colonies and other pests. The active ingredient in Ultraforce Termite Foam is the industry standard of 0.6 g/kg of fipronil. Colonies of R. flavipes in our study area tend to be localized with foraging areas generally not extending beyond five linear meters (Parman and Vargo 2008), although one of the treated colonies (property HI, Fig. T. R. CARCINOGENESIS: Research done on rats fed with fipronil for two years showed that it caused thyroid tumors in rats fed high dose of fipronil. Every day we get exposed to harmful chemicals such as Fipronil without realizing it. In a previous study performed in Raleigh, NC, using similar methods to those applied here, we (Vargo 2003) found evidence for colony elimination and reduced termite activity in an apartment complex treated with baits containing hexaflumuron. It's also considered a broad-spectrum insecticide as it targets numerous outdoor pests in commercial and residential areas. Working with R. flavipes, Bagnères et al. We genotyped all samples by using microsatellite markers to identify the number and locations of colonies present on each property. R. W. In veterinary situations, fipronil products are used as spray-on or concentrated spot-on formulations to control fleas and ticks on cats and dogs. The amount of fipronil taken into the body across the skin depends on the product formulation. (2004). How to Use. It can be used in low doses to cause a minimum harm to the environment. Samples were first identified to species using the polymerase chain reaction (PCR)-restriction fragment length polymorphism method of Szalanski et al. Nonetheless, there seemed to be a strong effect on most of these colonies. Researchers applied a dose of 79% Fipronil to the skin of rats and found that less than 1% of Fipronil was taken into the body after 24 hours. Fipronil can be used as an effective termite control as well as preventative treatment. As the foam enters the void cavity and dissipates (usually within six minutes), the fipronil sticks to the sides of the cavity to create a sub-lethal dose, therefore enhancing the slow acting transfer properties that fipronil has become famous for. The inner ring consisted of monitors placed ≈0.5 m from the foundation wall and positioned 2–6 m apart. Instead, they have time to contact, and feed, many other colony members and transfer the product, so the whole colony can be eliminated. Side effects of fipronil and when to report them Fipronil has very low toxicity to dogs, humans and other mammals, so adverse reactions are rare. Hillery Fipronil is used to control ants, beetles, cockroaches, fleas, ticks, termites, mole crickets, thrips, rootworms, weevils, and other insects. N. A. Monitoring stations were constructed from 6 cm-wide polyvinyl chloride (PVC) tubing as described by Parman and Vargo (2008). Fei 2007, Saran and Rust 2007, Spomer et al. Today, there are numerous insecticides used by pest control professionals for termite treatments. Since termites are social creatures, when they come in contact with the product, they do not die immediately. In our previous study on colony-level effects of imidacloprid treatment, we also saw about a 67% decrease in the activity of the inner monitors (Parman and Vargo 2010). Ibrahim et al. Moreover, it is an ingredient in some tick and lice control medications for pets. Genotypes were scored by comparing the fluorescently labeled PCR products to size standards by using GeneProfiler version 3.56 (BD Biosciences Bioimaging, Rockville, MD). Fipronil Fipronil is an extremely active insecticide belonging to the phenylpyrazole family. da Costa, Jainaldo Alves The other is imidacloprid. . In topical application assays, fipronil was highly effective against both workers and soldiers at very low doses. It is also suitable for wood treatments where 0.1% of concentrate is applied to wood for 3 minutes. The locations of monitors around two representative houses are shown in Figs. Finally, we considered colonies located in the outer ring of monitors or in the natural areas to be untreated colonies. Fipronil is an active substance in Termidor trademark products . Edward L. Vargo, Vincent Parman, Effect of Fipronil on Subterranean Termite Colonies (Isoptera: Rhinotermitidae) in the Field, Journal of Economic Entomology, Volume 105, Issue 2, 1 April 2012, Pages 523–532, https://doi.org/10.1603/EC11155. R. A. Toxicity of fipronil was evaluated against field-collected Coptotermes formosanus Shiraki. Subterranean termite is a real hidden pest. Wood debris in natural areas was checked semiannually for 3 yr. All 11 of the treated colonies (those attacking structures) disappeared within 90 d of treatment and were not found again. 2007) and liquid treatments (Parman and Vargo 2010). The main use of this product is to control termites in various structures but it’s utilized in baits in meadows in a granule form. These authors suggested that any potential colony-level effects of fipronil would be limited to areas within 5 m of the site of treatment. Luppichini The strong family structure of colonies in the study population, nearly all of which were founded by a monogamous pair of reproductives (Parman and Vargo 2008), together with the high genetic variability exhibited at Rf 24-2, with up to 36 alleles present in the local R. flavipes population (Parman and Vargo 2010), make colony identification straightforward and accurate. A. L. Fipronil, the active ingredient, is a very powerful insecticide. B. M. The "transfer effect" of Termidor has been observed through controlled scientific testing using C14 radio labeled fipronil on live termites. It results in fast spreading of the toxin to the other colony-members) For drywood termite infestations, it is necessary to apply 0.1 – 1 g per an injection point in wood. In addition, we checked mud tubes and any infested wood in the structure for termite presence. Treatment Stickers - Sherwood Chemicals Australia Pty Ltd Level 3, 1060 Hay Street, West Perth 6005 Australia Telephone: 08 9219 4683, Fax: 08 9219 4672, ABN: 351 369 936 30 In China, two of three baited colonies of Odontotermes formosanus (Shiraki) stopped foraging in trees and bait stations after 120–150 days when fed 40 ppm fipronil baits (Huang et al. Anyway, scientists inform all homeowners, that they should use it only with a pest control specialist. A. E. It is important to take precautions to make sure no gaps are left in the chemical barrier. they were less likely to feed on monitors because there were more natural food sources present on the properties. Gerard Ahmed Another possibility is that the effects of fipronil treatment were stronger than those of imidacloprid so that some of the untreated colonies eventually entered treated soil during the course of the study and suffered colony-level effects. Shelton and Grace (17) in a simple donor-recipient test exposed C. formosanus workers to sand treated with fipronil at 1, 10, and 100 ppm for 1 h. Mean mortalities of termite donors after 14 d were 36, 36, and 98%, respectively. In nearly all cases, we analyzed 10 individuals per sample (i.e., foragers present in the same monitoring station, piece of wood debris or mud tube), but in a small number of cases fewer than 10 individuals were present. Sheikh Only an expert can find out for sure where they can be. C.
