On an earlier gardening thread I talked about our solution, a 10 gallon bucket. Fill halfway with water, float enough striped sunflower seeds on the top of the water to cover it. Set it next to something the vermin will climb up on. Have some cheap tongs ready to fish out the carcases. Between last fall and this year we have gotten dozens of squirrels, many more dozens of chipmunks and a good amount of mice.
My aunt does something similar to catch ground mice where she doesn’t want them.
She doesn’t want me to kill it(them)...so I’ll just have to treat it as a friendly rivalry.
I’ve already taken to peeing outside. Not sure if it’s going to help, but I’ve been seen once by the neighbors and found it amusing. Will continue.
