Fruit Flies are simple to control BUT you need to make sure you have fruit flies first. Many people mistakenly think they have fruit flies but infact are dealing with drain flies. Check for any rotten food/fruit that should be fairly obvious. If you cannot find where the flies are feeding you are probably dealing with Drain flies at which point you should visit our drain treatment page or click here to use our Drain Fly Kit to fix the problem. If you do find rotten food/fruit dispose of it, and then utilize a fruit fly trap to catch any remaining adults to solve the problem.
