Q: I love to work in my garage with the door open when it’s too hot or sunny outside. My problem is that I have gotten various stinging insects camping out in the yard or garage most every year. Last year was particularly bad. They set up in an existing, 1-inch hole in the plaster on the garage ceiling. I want to be able to work there, but they seem to find a different place every year. I’ve always patched or covered up the spot, but I can’t get to the ceiling and I don’t know how to plaster. Short of hiring someone to patch the hole, do you have any ideas?
