We had the same problem, what we did was put little petrie type dishes out and filled them with
soapy water AND in a spray bottle we used soapy water and misted them and it got rid of our problem. Also for other bugs around the outside and you don't want them inside the best thing you can do (AND this works for termites especially plus spiders, roaches and other crawling bugs) PLANT BASIL PLANTS AROUND YOUR HOME, BASIL PLANTS ARE A NATURAL REPELANT TO THESE CREATURES AND OUR BUG MAN TOLD US TO DO IT... WE DID (8 TO 12 PLANTS) AND IT WORKS!!!!!!!
