I am not sure if I have get rid of all the unwanted guests (mice). Now, I am infested with flies. It all started the other day when I left a tub of shrimp shells in the garbage bin outside the house. I guess I forgot to cover it properly A group has departed but some seems to feel at home and stayed. I don't know where they came from. Must have a nest somewhere. How do I get rid of these unwanted guests before it starts contaminating us.
Use Raid at the location where the shrimp shells were left, and also at other locations where garbage gets stored even for a short time.
The "nest" is where you see maggots and is likely to be near where you see flies congregate. It can be inside a garbage can. Maggots, if unkilled, turn into flies. The group that departed was probably new hatchlings.
By the way, a dead mouse can become such a "nest". Been there seen that.
Tornado victims: Do not rush to rebuild. Take your time and look for and get a good contractor. Or consider selling the property and moving to a home that is ready to live in.
