Evolve Rat Birth Control - 6 lb Refill
Best value for serious rat management.
The 6 lb refill is the most cost-effective way to maintain your Evolve rat control program. Ideal for larger properties, farms, commercial facilities, and pest control professionals managing multiple accounts.
How It Works
Evolve's active ingredient — derived from cottonseed oil — disrupts reproductive function in both male and female rats. Within 1-2 breeding cycles (4-6 weeks), populations begin to decline. No rebound breeding like you see with poison.

Product details
How It Works
Evolve uses a proprietary formula that reduces rodent fertility. Place bait in stations and rodents consume it alongside their regular food sources. Over time, reproduction slows and the colony naturally shrinks -- without poison, without secondary kill risk, and without the rebound breeding that traditional rodenticides cause.
Usage Instructions
Place bait stations along walls, near burrows, and in areas with known rodent activity. Check and refill stations regularly to maintain a consistent bait supply. Results build over 2-4 weeks as the active ingredient takes effect on the rodent population. For best results, use multiple stations to cover the full activity area.
Safety Information
Evolve is EPA-registered as minimum-risk under FIFRA Section 25(b). It contains no anticoagulants, no neurotoxins, and no restricted-use chemicals. Safe to use around pets, children, livestock, and wildlife. There is no secondary poisoning risk -- predators that consume affected rodents are not harmed.
Shipping & Returns
