Hi, I'm Cher. Welcome to JustAnswer.I'm reviewing your question now and will post back with your reply, shortly.
Hi again, Bob.
I'm so sorry you're having these problems.
You can hire an exterminator who will not kill the animals and who will have a spring-loaded trap for the squirrels (or chipmunks) that will not allow mice to get inside or out, after eating the food bait.
While the exterminator is up in the attic, s/he can look for any areas where light is coming in, and those will be the places to be sealed up, once you know there are no more critters in the attic. If you're a DIY man, you can seal up the spaces yourself from the inside and outside (if possible) or call a handyman or contractor to do it.
Check the areas where the roof/eaves meets the gutters, too, as there might be a some small holes, there.
I wish you much good luck and hope your problem is resolved very soon!

Hi again, Bob and thanks so much for your reply.
I have experienced a squirrel in the attic, but I set a humane trap, but food in the back and within a short time, I caught the squirrel. I was told to leave the trap there and baited again, as they usually travel in pairs, but we never caught anything in the second trap, so it was removed and the hole where they were getting in was sealed up by a professional.
I found a great article that might help you, and it states that unfortunately, the ultrasound transmitters, mothballs and other techniques people use are ineffective, so, see if this helps, and you might have to get professional help to set up certain types of traps at the points of ingress and egress, to get them out, permanently:
They're not going to leave on their own if they have a nice, warm, cozy 'home' in your attic, so that's why the suggestions at the website above should be helpful.
I hope you start making some progress with this new information!
I'm sorry I couldn't have been of more help, Bob. I'll opt out and leave your question open to other experts.
I wish you much good luck!
Good afternoon Bob,
The expert earlier was correct in many of the tips provided as this is what is recommended by many professional exterminators. What I have also done is to research some humane as well as tips that are offered by those that have used these ideas to make sure these pests do not decide to visit again.
1. A number of household experts have stated that "peppermint oil" works well in making sure these pests do not return. Found in natural food stores, spray around the area with water or on cotton balls in the attic. This has been found to be effective indoors as outdoors the scent can wash away.
Give this remedy a try before your last resort which is a pest expert to visit your attic.
