A Maine grassroots coalition

Rat poison doesn't stop
at the rat.

Second-generation rodenticides move up the food chain — poisoning owls, hawks, foxes, and family pets. Rodenticide-Free Maine works to end unnecessary rodenticide use and make sure Mainers know what's in their neighborhood.

Who we are

A coalition of Mainers who noticed

Rodenticide-Free Maine formed when biologists, ecologists, and neighbors kept finding the same thing: bait stations appearing on properties across the state with little to no information given to the people living nearby.

We work alongside Maine Audubon and other conservation partners to reduce the use of second-generation anticoagulant rodenticides (SGARs) in outdoor residential settings, and to push for clear, upfront disclosure whenever bait stations are placed on shared or rented property.

Coalition Lead

Jacquie Gage

Belfast-based biologist and educator who helped organize the coalition and has testified before the Maine Board of Pesticides Control.

Coalition Member

Heléna Malone

Advocate working directly with Maine residents and tenants to document rodenticide use and push for public disclosure.

Ecologist

Richard Podolsky, PhD

Ecologist specializing in ornithology, focused on the impact of rodenticides on birds of prey and other wildlife.

Why it matters

One poisoned rat, many victims

Second-generation anticoagulant rodenticides (SGARs) are potent enough to kill in a single feeding — and they stay in an animal's body long after.

Built to persist

Brodifacoum, bromadiolone, difenacoum, and difethialone are the four SGARs restricted under Maine's new rules. They're more potent than older poisons and can remain in an animal's tissue for months.

Secondary poisoning

Predators and scavengers — owls, hawks, eagles, foxes, coyotes, bobcats, and outdoor pet cats — are exposed when they eat a poisoned rodent, not just when they eat the bait directly.

Moving up the chain

SGARs bioaccumulate — each animal that eats a contaminated prey item passes a higher dose further up the food chain, well beyond the original target.

Policy progress

Where Maine's rodenticide law stands

LD 356 directed the Board of Pesticides Control to move toward prohibiting rodenticides in outdoor residential settings. Here's the timeline so far.

2025 — 132nd Legislature
LD 356 enacted
"Resolve, Directing the Board of Pesticides Control to Prohibit the Use of Rodenticides in Outdoor Residential Settings" (Resolve 2026, c. 47) directed the Board to review and restrict rodenticide use around Maine homes.
Early 2026
Board rulemaking & public testimony
The Board of Pesticides Control held hearings on proposed amendments. Coalition members, including Jacquie and Heléna, submitted oral and written testimony.
June 16, 2026
Four SGARs reclassified as Restricted Use
Brodifacoum, bromadiolone, difenacoum, and difethialone can now only be bought and applied by licensed pesticide applicators — homeowners and general retailers can no longer sell or use them (01-026 CMR Chapter 40).
Ongoing
Full outdoor residential prohibition
LD 356's ultimate direction — prohibiting rodenticide use in outdoor residential settings entirely, unless applied by a certified pest control company — is still being implemented through further Board rulemaking.

What this means today: the strongest consumer rodenticides now require a licensed applicator. If you see a bait station on residential property, it should generally have been placed by a certified professional — and residents/tenants should be told it's there.

Get involved

Found a bait station with no explanation?

That's exactly the gap this coalition exists to close. Here's what you can do.

Document it

Photograph the station and any visible label. Note the location, date, and whether tenants were notified in advance.

Know your rights

Ask your property manager who placed the station, what active ingredient it contains, and whether the applicator is licensed.

Report it

File a tip with the Maine Board of Pesticides Control: 207-287-2731 or pesticides@maine.gov.

Speak up

Support Maine Audubon's petition and contact the coalition if you want your case included in future testimony.

Every bait station tells a story.

Help us make sure Mainers hear theirs — before the poison reaches the next animal up the chain.
