Short answer
Only in a locked, tamper-resistant bait station, and not indoors. EPA rules require consumer rodenticides to be sold in tamper-resistant stations, and bar the longest-lasting anticoagulants from consumer products because they linger in the tissue of poisoned rodents and poison the pets and wildlife that eat them. Inside a house, traps are safer and work better.
Since the EPA's rodenticide restrictions, consumer rodenticide products must be sold as ready-to-use bait stations that contain the bait and resist tampering by young children and dogs, and they're labeled for indoor use or for outdoors within 50 feet of a building. The second-generation anticoagulants, the strongest and longest-acting, are no longer registered in consumer products at all; only bromethalin, chlorophacinone and diphacinone are allowed in what a homeowner can buy. Professional products require tamper-resistant stations anywhere children under six, pets or wildlife could reach them. Loose bait blocks or pellets on a garage floor are exactly what the rules exist to stop.
Two problems the label warns about. The EPA notes second-generation anticoagulants tend to remain in animal tissues longer, which is why a cat, dog, hawk or owl that eats a poisoned rodent can be poisoned too, and why those products were pulled from consumer sale. The second problem is where the rodent dies. Poisoned mice and rats go back into the wall, the ceiling or under the floor to die, and Utah State University's extension advice against indoor rodenticides is blunt: dead mice decay inside walls. The smell lasts weeks and there's no way to reach the body.
Traps indoors, stations outdoors. Snap traps and multi-catch traps kill or hold the mouse where you can see it and remove it, and set correctly, six or more, no more than 10 feet apart along walls where there's activity, they clear a house faster than bait. Outside, where rats are burrowing along a foundation or bulkhead, bait in a locked, tamper-resistant station that's checked and serviced is the right tool, placed where children and pets can't get to it and the dead rodents can be found. If a child or pet does get into bait, call Poison Control at 1-800-222-1222 or your vet immediately with the product name.
This is how we work every rodent job: traps inside the house, locked stations outside, and we tell you where every one is before we leave. The calls we get after a homeowner used loose bait are the ones nobody wants: a dog that ate a block in the garage, or a mouse that died in the wall behind a kid's bedroom in a Levittown cape. Bait has its place on the bulkhead side of a canal-front house in Massapequa; it doesn't belong in a kitchen.

Call your vet or Poison Control at 1-800-222-1222 immediately, with the product name and active ingredient from the package. Anticoagulant baits cause internal bleeding that may not show for days, and there's a treatment if it's started early. Don't wait for symptoms.
Yes. That's secondary poisoning, and it's the reason the EPA removed the long-lasting anticoagulants from consumer products: those compounds stay in the tissue of a poisoned rodent long enough to poison whatever eats it. Cats, dogs, hawks and owls are the usual victims. Indoors, use traps so there's no poisoned mouse to eat.
We don't. Bobby Bugs uses snap and multi-catch traps inside, placed where kids and pets can't reach them, and locked, tamper-resistant bait stations outside only. A rodent that dies inside a wall is a problem we'd be creating for you, so we don't create it. Mouse and rat work carries a 60-day written guarantee.
