My smoke alarm was going off all day and driving me crazy. I just changed the battery last week! So I finally opened it up and there are ants crawling inside. They must be setting it off somehow, although none of them are smoking. They must have read my anti-smoking blog.
So, are these fire ants?
I was going to spray the area with pesticide, but I don't want to antagonize them. I hope after this is over, I don't need to call a carpenter.
