How to get rid of gnats

Question

I have tried evey thing to get rid of them and they are cooming through the screen door at night

Answer 1

If you have any fruit or vegetables that are out, you need to either put it in the fridge or throw it away.  If your house has anything that would draw gnats, i.e., dirty laundry, any kind of candy or sweets that are 'exposed' then the gnats will still 'find' a way to get in.  You can spray Skin So Soft (mix the oil with water, half and half) into the air around the screen, onto your rugs, anywhere there is cloth that can absorb the mixture, and that will repel them.  

Otherwise, you should use bleach to clean all bleachable surfaces and clean up any food leftovers that could be drawing the gnats.  Sometimes all it takes is a good bleaching of all surfaces and tile floors to discourage the little buggers from getting in.

Good luck!

Answer 2

I have also had luck with pouring some bleach down the kitchen drains.  Seems they like the accumulated food there.
