We spray the toilet & the garbage more than daily. We even sprayed the grounds & underneath the trailer, & still the gnats persist. Is there any way to get rid of them once they’re inside the house.
I have a problem with them in my house. The only way I have found to get rid of them is get some of those Bug Bombs. You know the type where you set it up, let it spray on it's own, and leave the house with all of your pets for a few hours.
This kills them everywhere. Even in the walls. I have to do it in my old house about twice a year.
