Buddy (who rents the house to me) had the house sprayed fairly recently but we still seem to have a fire ant problem- INSIDE the house. Have sprayed them countless times with all sorts of stuff inside, they just keep coming back. Have someone from Terminex coming in the morning, lets hope they do their job this time!! (as they just sprayed fairly recently).. Anything else that could be causing this?? House is in very good shape, no food around, etc..
