Proactive, Safe and Humane Approach to Rodent Control
Did you know that a single female rat can produce up to 15,000 little pups in her lifetime. Not to mention, rats have a short gestation period averaging three weeks — now that’s a lot of rats!
Addressing the rodent control dilemma has been a long-time issue faced by homeowners and business owners alike. Traditional rodent control methods include a reactive approach— rat bait, live traps, and rodent-proofing your home. Now, these traditional rodent control methods do indeed work well, but some come with drawbacks and undue risk.
Rodenticide Kills More Than Just Rats
Birds of prey, including eagles and owls, raccoons, and neighborhood cats and dogs can all be impacted by secondary poisoning from rodenticides. Further, rodenticide kills rodents effectively but you cannot control where they die. They may crawl into your insulation or wall voids to decompose.
Ethical Considerations
When a rat consumes rat poison, they gradually experience a wide range of symptoms, including painful internal hemorrhaging, seizures, weakness, and difficult breathing.

Unlike Rodenticides, ContraPest is an Innovative, Humane and Non-Toxic Liquid-Based Birth Control Formulated to Reduce Fertility and Reproduction Rates in Rats & Keep Them Down.

Frequently Asked Questions
What’s in ContraPest?
ContraPest is a liquid fertility control bait, specifically formulated for male and female Norway and Roof rats which inhabit Gig Harbor and Fox Island. The active ingredients are VCD and triptolide. VCD is an inorganic compound and triptolide is a product extracted from the thunder god vine (Tripterygium wilfordii). Male and female rodents who consume ContraPest become “reversibly infertile” much like human birth control pills.
When is ContraPest the best option to control rats?
While the vast majority of rodent issues can be effectively controlled with Fox Island Pest Control’s Quarterly Preventative Pest Control services, ContraPest is an ideal solution for clients with un-securable crawlspaces where rodents like to nest, clients with chicken coops, bird feeders, vegetable gardens or fruit orchards that attract rodents, or homes and business that are adjacent to wetlands, shorelines or other natural rodent harboring and reproducing environments.
Is it safe for birds of prey and other wildlife?
Yes. ContraPest is digested into inert byproducts in the rodent’s liver so it does not harm predators who eat the rodents.
How fast does it start working?
You should expect rodents to become infertile after about 70 days and they will become fertile again if they stop consuming the product.
Is it safe around pets and kids?
Yes, when used properly. The liquid is enclosed in a tamper resistant box to protect kids and pets. It’s thought to cause mild skin irritation to humans and may cause transient infertility in small mammals if ingested in large enough quantities. For more safety information, you can request the product safety and data sheet from Fox Island Pest Control via the link at the bottom of the page.
How effective is it?
Independent research studies report up to a 95% reduction in rodent populations. In addition, unlike rodenticides, no rebound in rodent populations were observed.
Why is the service so expensive?
The active ingredient is pharmaceutical grade triptolide which is very pricey. ContraPest is about seven times more expensive than traditional rat poison. Note that Fox Island Pest Control’s Premium Rat Fertility Control Service with ContraPest also includes our year-round Comprehensive Pest Prevention Service which includes control of most insects as well, including ants, spiders, stinging insects and more.
Can I split the cost with my neighbors?
Sure! Since one station covers up to 15,000 square feet (that’s over 1/3 of an acre!) its likely that you’ll be helping out several neighbors when you use Fox Island Pest Control’s Premium Rat Fertility Control Service with ContraPest on your property. Please note that while you can choose to collect money from your neighbors, we can only bill one person for the service.
Is rat birth control available for restaurants and commercial spaces?
Yes! ContraPest is exceptionally tasty for rats, making it a great alternative in situations where competing food sources can’t be eliminated. Open dumpsters, food scraps, etc. often draw rodents away from poison bait or baited snap traps which reduces their effectiveness. Request an inspection and we’ll see if your retail store, warehouse, or food facility is a good fit for rat birth control.
