This Product REALLY works!

I have a small sanctuary including rescued bird and chickens. I used to have rats in the aviary and rats in the chicken coop. I was constantly catching rat pups in humane traps but I couldn't catch the parents (too smart) so the breeding went on. Now I have NO rats in the chicken coop at all. None. I have a rat or two who visit the aviary and once in a while I see an adult on my back porch. If you have chickens you definitely want this product.

Easy to use, safer, humane, effective!

In Colorado, I’ve found both ContraPest (used in summer) and Evolve (winter) are helpful and easy to deploy using the Ultimate Bait System (Weighted Block). Highly recommend using Senestech products to more safely and humanely help control rodent fertility and subsequently reduce populations without harming other creatures.

An Easy Alternative to Contrapest

While ContraPest is recommended for commercial use, some consumers should consider Evolve™ for their rat control needs. Evolve is easier to deploy, more affordable, non-toxic, and poses little to no risk to people, pets, wildlife, and the environment. It’s a better option for consumers on a tight budget or anyone looking for a more simplified rat control process.

Does ContraPest work on any species other than rats?

No. ContraPest is specifically formulated and EPA registered for controlling rat pest populations.

Can I purchase or ship ContraPest outside of the United States?

ContraPest is only registered for use in the United States, District of Columbia, and five major US territories. While federally classified as a general use product, in the state of Connecticut you must have a restricted use license to purchase.

What happens if my dog or other house pet consumes ContraPest?

Always follow the label when deploying ContraPest. When properly deployed ContraPest poses extremely low risk to non-target species.

I lost my bait station key. What do I do?
