Why We Don't Put Rodent Poison in Your House

The Thing Nobody Explains Before They Install One

If you call most pest control companies about mice, a technician arrives and places black plastic stations inside your home. You will probably be told they are tamper-resistant. That is true, and it describes the box rather than what is inside it.

What is inside is usually an anticoagulant rodenticide. It does not work instantly. A mouse feeds, then goes about its business for several days before the dose takes effect. It does not come back to the station to die, and it does not politely expire on the basement floor. It dies where it feels safest, which is inside a wall void, above a ceiling tile, under insulation, or in a soffit.

Then You Have a Second Problem

A dead rodent in a wall cavity is not something anyone can reach without opening the wall. It decomposes there. In a heated house in January that runs for weeks, and it brings its own follow-on problem, because blow flies and cluster flies find the carcass and hatch inside your wall.

We get calls every winter from people who solved a mouse problem in December and have a fly problem in February, and who have no idea the two are connected. They are the same event.

What Else Eats a Poisoned Mouse

This is the part that matters most on Long Island, where a lot of properties back onto woods, preserved land, or open field.

A rodent carrying a dose of anticoagulant is slow, disoriented, and easy to catch. That makes it a preferred meal. Red-tailed hawks, great horned owls, screech owls, foxes and neighborhood cats all take rodents, and the dose goes with the meal. This is called secondary exposure and it is well documented in raptor populations across the Northeast.

If you have owls on your property, they are doing free rodent control for you every night. Bait works against them.

There is also the direct risk. Bait is formulated to be attractive to a mammal, and a dog does not know the difference between a bait block and a treat. Neither does a toddler who finds a station behind the dryer.

So What Do We Do Instead

Mechanical snap traps, placed in the interior runs where rodents actually travel: basements, utility rooms, under and behind appliances, along wall lines. Checked, cleared and reset at every scheduled visit where you give us interior access.

Trapping is slower on paper. A bait program can knock down a population faster on a spreadsheet. But trapping has a property that bait does not: every rodent it kills ends up in a trap you can see, in a spot we chose, and it leaves the house in a bag. Nothing dies inside a wall. Nothing gets eaten by something else.

The Honest Limitation

We are not going to pretend trapping is a complete answer, because it is not. Traps remove the rodents that are already inside. They do nothing about the quarter-inch gap those rodents used to get in, and as long as it is open, new ones keep arriving.

That is why we note entry points at every visit and show you exactly where they are. Sealing them is carpentry rather than pest control, so it is quoted separately, and it is the only thing that actually ends the problem. We would rather say that plainly than sell you bait every month for the rest of your life.

A Question Worth Asking Anyone You Call

"If I have mice, are you putting poison inside my house, and where exactly does the mouse die?"

The answer tells you a great deal about who you are talking to.
