Mosquitos Breeding in the basement sump pump!
The temperatures outside have been in the 30s and 40s during the day and in the 20s at night, so we could not believe we were seeing the occasional mosquito. Finally figured out that they were breeding in the sump pump under the basement stairs. ICK! They are very snall and are not biting, but still... Winter is not the time for buying mosquito spray or other stuff to kill them. We poured bleach into the sump pump water, but that didn't work. Any ideas?
