Yes, Really!

Q: Targets Fertility in Both Sexes

Prevents reproduction in Norway rats ( Rattus norvegicus ) and roof rats ( Rattus rattus ).

Sustainable Rodent Population Control

ContraPest^® Is An EPA-Registered Contraceptive

ContraPest® was developed by scientists specializing in rodent fertility control. It’s the first contraceptive that works on both male and female rodents—helping to create healthier environments by reducing populations both humanely and sustainably. By restricting fertility in both sexes, ContraPest® offers a proactive solution that targets the root of the problem: reproduction.

How ContraPest® Works

Targets Fertility in Both Sexes

Prevents reproduction in Norway rats (Rattus norvegicus) and roof rats (Rattus rattus).

Humane Approach

No painful trapping or secondary poisoning risk to wildlife or pets.

Easy Maintenance

Installed and serviced by professionals; bait tanks are simple to replace.

Prevents Population Rebound

By reducing breeding, future infestations are less likely to occur.

Curb the Next Rodent Baby Boom – Before It Starts

The Sentinel functions not only as a trap but also as a physical barrier within the sewer system—preventing rodent movement into protected areas at all times. Rodents cannot lift or bypass the built-in locking system, ensuring continuous protection.

Proven Results:

Washington, D.C. saw a 90% reduction in rat activity at test sites within one year of using ContraPest®.
San Francisco Recreation & Park reported a 65% drop in burrow counts over a year after integrating ContraPest® into their program.

This system supports a preventive, large-scale control strategy—stopping infestations before they reach the surface.

Rodent Control

ContraPest is the first EPA-registered contraceptive for both male and females developed by rodent fertility control scientists to create healthy environments by virtually eliminating rodent pest populations. Designed to restrict fertility in both sexes.
