We have traps inside. But need to know if there is something we can place around the foundation to PREVENT them from entering. All visible holes have been plugged. Thank you.

    They will be looking for Food/Shelter if your basement is offering that and you don't want them to move in, You could put up a notice saying "NO MICE IN THIS HOUSE" - they won't take any notice?? Call in the Cat Patrol- If you do, You won't have mice. A nice Cat should do it.............
  • If they are still getting in, the holes are not screened or plugged. Call a reputable exterminator for an inspection - they know where to look. Then heed their advice for plugging or screening off. A mouse can fit through a hole the size of a dime and a rat, the size of a quarter. If you have pets or kids, be careful using any poison.

    Naomie is right, they are getting in from somewhere. We had a mouse problem and still do, just not on such a large scale as before.
    Here's what we did, we had to call an exterminator, the company came out and assessed the number of them and promptly had the skilled technician look with a trained objective eye. He located and filled in all the possible entrances he could find with a black foam, this foam hardens and they cannot chew through it, it will cut their face. This took repeat visits.
    They enter from pipes that come into the house, enter where electrical wires come in, tiny cracks in the foundation, they are very cleaver.
    You are lucky to just have them in the basement, we were totally infested. You will have to seal up and box up all potential sources of food, they ruin lots of stuff.
    Put down sticky traps, they like to have a pattern in the room, so put them where they have a route.
    Dcon was ignored, so they won't eat the bait.
    Set the conventional traps with what they are devouring.
    There is nothing I know of that you or anyone can put around the periphery to prevent them from trying to get in.
    One small consolation is they only live for about 8-9 months and hope no pregnant females are in your house.

    Just because you find them in your basement doesn't mean that's where they entered. Have you checked attic and looked for holes along all outside facing walls? Remember that they climb so just like squirrels can get into your attic imagine a mouse. So if you can go into attic or hire someone and let them look and place traps or poison up there and for foundation walls also check above foundation on first floor it might be easier at night with two people and on phones with a flashlight. One on the inside to go along the baseboard the other on the outside to see if they can see any light coming through. Don't forget door thresholds and especially if you have a garage connected to home. I have been told by an exterminator that they don't like copper netting so wrap that wherever water comes into your home. Don't forget your outside water valves. Good luck.
