Should I use poison to kill the squirrels?

No — and not just because it's a bad idea. There is no registered or legal poison for squirrels anywhere in the United States. Every "squirrel poison" you'll find online is either rat poison being marketed off-label or a homemade recipe, and both are illegal to use on squirrels.

Will rat poison kill squirrels?

It can — but here's what actually happens when people try it:

• The squirrel dies inside your walls. Poisoned animals retreat to their nest, which is usually a wall void or attic corner. The result is a weeks-long odor problem and a demolition-level cleanup job that costs far more than proper removal.
• Secondary poisoning kills pets and raptors. Dogs, cats, owls, and hawks that eat a poisoned squirrel ingest the poison too. This is a leading cause of raptor deaths in Kentucky.
• It doesn't solve the problem. Poison does nothing about the entry hole. As long as the opening exists, the next squirrel moves in — often within days.

Is it legal to poison squirrels in Kentucky or Indiana?

No. Squirrels are classified as protected game species in both states, and using any pesticide in a manner inconsistent with its label is a violation of federal law (FIFRA). Using rat bait on squirrels checks both boxes. You can read more about what Kentucky and Indiana law allows for squirrel trapping and removal.

What actually works: humane exclusion

The permanent, legal solution is exclusion: we install one-way doors over the active entry points so squirrels exit on their own and physically cannot get back in, then seal every gap in chew-proof steel and metal flashing. No carcasses, no odor, no repeat infestation — and it's backed by a lifetime warranty. Learn how exclusion works or why humane removal is the industry standard.
