UC Irvine

UC Irvine Eliminated Rodenticides from 267 Bait Stations

267 bait stations. 98% acceptance. Zero poison. UC Irvine replaced all rodenticides with Evolve and reordered for continued use.

A 9-month field trial at UC Irvine's University Hills residential community replaced rodenticides in all 267 bait stations with Evolve.

The results:

98% bait acceptance rate
Decreased rodent complaints across the community
Complete elimination of toxic pesticides from common areas
Multi-pallet restocking order for continued deployment

The program partnered with the HOOT Group (Help Our Owls Thrive) to install barn owl nesting boxes alongside Evolve stations — protecting natural predators while managing rodent populations.

Municipal Adoption

Baltimore

Baltimore Expanded Evolve Citywide After Successful Pilot

Baltimore adopted Evolve citywide in 2025 — replacing poison in public spaces. Proof the technology works at city scale.

The City of Baltimore adopted Evolve in January 2025 as part of its integrated pest management strategy. After a successful pilot phase showed measurable improvements in rodent activity, the city expanded deployment in June 2025 to additional sites.

Why it matters:

Validates Evolve for large-scale urban rodent management
Proves the technology works at city scale
Shows government agencies are ready for non-toxic alternatives
Replaced traditional rodenticides in public spaces

Baltimore's adoption signals a shift in how municipalities approach rodent control — from poison-based extermination to sustainable population management.

CA Almonds

Protecting California Almond Orchards Without Poison

Protects orchards without harming hawks and owls. Zero contamination risk. Keeps your natural predators working for you.

California almond growers face persistent rodent damage to irrigation lines, seedlings, and equipment. Traditional rodenticides create a cruel paradox — they kill the hawks and owls that provide free natural rodent control.

Evolve solves this:

Reduces rodent populations without harming raptors
Protects irrigation infrastructure and stored crops
Zero risk of contaminating harvested products
Integrates with existing IPM programs
EPA minimum-risk classification simplifies compliance

For California tree nut growers, Evolve isn't just a rodent control product — it's an ecosystem management strategy that keeps your natural predators working for you.

From California neighborhoods to international government programs

Deployed Around the World

San Francisco

Reduced visible rodent activity and decreased poison usage across urban deployment zones. Proves Evolve works in dense metropolitan environments.

Hong Kong

Rodent sightings fell dramatically within 3 months. No new litters detected in treated areas. International validation of Evolve's effectiveness.

New Zealand

Government approved Evolve for the Predator Free 2050 initiative — a $4.5B national program to eliminate invasive predators from the entire country.

Poultry Farm

Evolve deployed in agricultural poultry operations where traditional rodenticides posed contamination risks to the food production environment.

Backed by 29 Peer-Reviewed Studies

Fertility control proven in 29 peer-reviewed studies. EPA minimum-risk classification. No secondary poisoning risk to wildlife.

Evolve's active ingredient — gossypol, derived from cottonseed oil — has been studied extensively in peer-reviewed scientific literature. The Evolve White Paper compiles 29 published studies demonstrating:

Proven mechanism: Gossypol reduces sperm motility in males and disrupts egg development in females, causing natural fertility decline across treated populations.

Safety validated: EPA FIFRA 25(b) minimum-risk classification. No carcinogenicity. Low toxicity to non-target species including birds. Reversible fertility effects — rodents aren't permanently sterilized, they simply reproduce less.

No secondary poisoning: Unlike traditional rodenticides that bioaccumulate up the food chain, gossypol poses no risk to predators that consume treated rodents.

California Is Restricting Rodent Poison. Here's the Alternative.

AB 1788 restricts rodent poison on state lands. Evolve is the proven non-toxic alternative — available now in California.

California's AB 1788 restricts second-generation anticoagulant rodenticides on state-owned lands — and the regulatory trend is accelerating. Cities, counties, and agencies are actively seeking non-toxic alternatives.

Evolve is the answer the market has been waiting for. The same science that UC Irvine validated, that Baltimore adopted citywide, and that New Zealand approved for a national conservation program — is available right here in California.

If you're a property manager, pest control professional, farmer, or government agency looking to move beyond poison, the proof is in.

What Is FIFRA 25(b)?

Evolve is EPA-registered under FIFRA Section 25(b) — the minimum-risk exemption for products that pose little to no risk to human health or the environment. Here's what that means.
