We are going crazy with an infestation of INDOORS midges/gnats in our home. We are open to any idea since we have tried anything else. Perhaps timer/foggers with a non dangerous spray for the rooms?
There are a few options that can handle this problem. You could manually use a space spray like AQUACIDE on a daily basis. Treat the rooms where they're active once in the morning and once again at night before you retire. This will knock out the active ones and over time should get rid of them all.
A more permanent solution would be set out an AEROSOL MACHINE which runs automatically. These can be placed in the rooms with the most activity and can be set to disperse some product every 15 minutes if needed. Fill them with KONK. Over the course of a month it will have a big impact and could solve the problem by killing all active adults before they're able to reproduce if the problem is based inside the home.
