When people find rats, a lot of them head to the hardware store for poison bait. We understand why. It's cheap and it seems simple. But in a house, poison often causes as many problems as it solves.
The smell problem
Poisoned rats don't die right away, and they don't die where you'd like them to. They go back to where they feel safe, which is often inside a wall, under insulation, or deep in a crawl space. Then they decompose. The smell can last for weeks, and finding the source can mean opening up a wall.
Risks to pets and wildlife
Bait doesn't just get eaten by rats. Dogs find it. And predators like owls, hawks and neighborhood cats eat poisoned rodents and can be poisoned themselves. That's why the EPA has restricted some of the strongest rodenticides from consumer sale.
It doesn't fix the cause
Even when poison works, it only removes the rats that were there. The gap they used is still open, and new rats will find it. You end up buying bait forever.
What works better
- Find the entry points: vents, utility gaps, rooflines, garage doors.
- Trap along active runways so you can confirm each catch and remove it.
- Seal every entry with steel mesh, sheet metal and sealant.
- Clean up contaminated insulation and nesting.
- Follow up until there's no new activity.
That's how we approach every rodent job. It takes a bit more effort up front, but it ends the problem instead of managing it. See rodent proofing and rodent exterminator services.
