Unless you just want to keep the little bugger alive, just one Bite. Will take care of any future infestations as well. Great stuff, but it is indiscriminate. So if you decide to give it a try don't put it anywhere other animals can access it. It is pretty unique that when the animal dies they are embalmed and do not give off an odor.

You've already investigated and sealed the obvious entry points. Get rid of the current critter. If another/more come in, then you look for more entry points, and perhaps call an exterminator who is versed in dealing with it. Be aware that mice like to chew wires. Happened to my neighbor, his refrigerator compressor went dead, found a dead mouse beneath with a wire chewed.

I suggest to get some mouse traps. They work great.

Mouse traps and peanut butter!

Agree that not all cats are good mousers. Growing up, we had a great one. Her mission in life was to exterminate all rodents. The current feline family members are apparently readers of Garfield. Mice are friends, not food.

Mice will chew through steel wool, you need to use copper mesh. Ultrasonic devices are worthless, they do not work.

a mouse can squeeze through an opening as small as the tip of your pinky finger. You need to seal all openings with rodent proof sealant,

I have battled mice in two homes . It is a no holds bared battle, hire a pest company and stop the infestation before it starts.. forgo

Use trap. Yes, you might have several. Try to figure out where it is coming from. Usually it will be seasonal. Cycle repeats but it is not endless.

I had them in my attic, finally found a spot in the garage where the back of the chimney didn't seal against the ceiling and they were getting up there. Sealed it up, no more scratching in the ceiling. They can find weird ways in. And you won't necessarily have more and more, this one could be an anomaly.

We had mice when we moved into our new construction home a few years ago. We inspected inside and outside and sealed up anything we saw where they could have possibly gotten in. We then set traps. We no longer have a mouse problem inside but outside is another story. My DH had to bring his car(Ford Fusion) in every month for 3 months due to the mice chewing the engine wires. Then they went after my car(Honda CRV) which was kept in the garage. They did a number on the wires requiring a whole new wiring harness. Wires in some cars are soy based which attracts the mice. They haven't touched the 96 Mercury Sable. So we have traps and poison bait stations set up in the garage and around our wood pile where they set up nests. We have gotten 5 so far this spring.

In just a couple of weeks of not using one of our trucks, mice made a nest in the engine compartment. My husband started the truck and blew the engine. It was a diesel. The insurance company did not total the vehicle, but they did pay the costly repair. All that said, I suggest a pest company. It has helped at our house, One got in recently, but the kitchen and garage doors were open to move things and we think it slipped in then.

I would never use a poison bait, and we have no kids or pets here. A neighbor in our old neighborhood did, and 'his' rodent went under the crawl space of my house, died. I worked about half a day with the exterminator trying to find the source of the stink. It was bad enough DH fled to his fathers, leaving me to deal with it.

It's nesting time here. Way too many types birds who would scavenge and take something tainted back to a nest where fledglings could be harmed. Not a tree hugger or extremist but I have no wish to harm wildlife either - baiting rodents could definitely harm them.

There is a 'family farm' still in the family. House has been gutted and completely remodeled - there is a nephew living there right now with two small children. It was once a working farm and always had a mouse problem. For as many decades as I can remember. No different for him, and he spent many hours sealing up any conceivable space where a mouse could get into the house. He finally pulled out the built in dishwasher and found the smallest of openings around the plumbing for it, sealed that and seems to have solved the problem after trapping, not baiting those in residence.

Neighbor mentioned he saw a mouse in his car. I told him DO NOT put poison in there, it'll crawl up in the dash or A/C ducts and die there. Too late, it did, in the A/C. He never got the stink cleared out of that car. Only way would be to disassemble the dash and A/C system for cleaning / deodorization which was more cost than he was willing to outlay. Another mouse (or maybe a family of them) later destroyed the wiring in that car to the tune of $24,000 repair estimate so insurance totaled it.

Peanut butter and a HD trap has never failed me, usually takes only a few hours. We used to get 1 mouse every 5 years or so before reno...just enough to freak everyone out!

Make sure you don't get the crappy traps with the yellow plastic bait thing with fake cheese holes in it. They are awful traps because they don't spring when they should, so you find them not sprung but with missing bait. I went to my Ace Hardware and got the good old fashioned mouse traps with the copper colored curled up metal piece that holds the bait. They work much more reliably.

We use electric mouse traps. You put peanut butter in, the mouse goes in, gets electrocuted and dies. Not poison, no springs. You open the box and dump the corpse in the garbage. Easy, neat and clean.

We lived in a different house for years. One year, we had a fly problem. Got screens, solved it. A few years later, it was ants. Got rid of them. Then it was mice. Got rid of them. Then my son was telling a friend in front of friend's mother, oh, we had fies everywhere and ants and all these mice! He made it sound like the house should be condemned, when it was a perfectly fine house.

The mice seem to like the house we bought last fall. Cat - 1. Husband - 24. Using the cheap wire sprung traps with peanut butter.

I have a mouse--I have tried the spring traps and glue traps--no luck--peanut butter as bait. I'm coming up empty. He's smart. He doesn't go near the trap.

Had success breaking off cotton end of a q-tip, then use pliers to tighten the cotton q-tip end in the metal bait area, then put chocolate fudge sauce on the cotton.

Good luck!

Ooh I like that idea.

So Debra the OP posts and is never heard from again. lol

I bought an electric zapper. I'm desparate man.
