Hello T.,
Check around your foundation to search for openings...dryer vents, holes, etc. Find a draft spot in the basement and fix that.
Check behind and underneath sinks, stove, attic openings etc. Mice can climb and tunnel.
Anything left out in your house will attract vermin. Containerize everything, Cereal, Rice, Macaroni, Flour, Sugar, etc. The mice are looking for a food source to take them through the winter.
Sonic Sound devices work, mice cannot stand the high frequency sounds. They are plug in devices.
Make your home unattractive to vermin.
I would imagine that Fox Urine can be purchased through hunting magazines or Big Box Hunting Outlets.
But lets deal with reality:
Trying to respect your husband's dislike of Cats is admirable, but I don't get from your article where he is trying to help you fight your mouse problem.
Unnatural remedies are often hazardous to other animals and small children that share the creature's domain. Natural remedies are evironmentally friendly and safe to humans.
Remind your husband that mice are a health hazard because they are carriers of disease and need to be dealt with seriously. Realize also that over time Cats also get to the point where they will "gift" you with a dead mouse as a love token (Don't get offended). This will be his offering to you in thanks for your love and care.
Give your husband a choice between getting a Cat or a Snake to control the Mouse problem. His choice will result in a compromise, a 50/50 partnership or a meeting of the minds between equals.
Sincerely,
Angie
