Lisa...here's a completely safe & organic way that could help in your situation...it's a product called "Fossil Shell Flour" or "Diatomaceous Earth" (D.E.) at:

 It kills pests physically not chemically...when the pests come into contact w/ the product it punctures the bugs body & the bug dies from loss of fluids, so the dying process takes longer but it does happen.It's feels like razor sharp shards to the bugs but to us it feels like soft flour... If you get the food grade D.E.(that's the one they call fossil shell flour) you can put it in the pets bedding, carpet & in the pets hair ( you need to get it to the skin not in the hair). I personally didn't like the feel of my Jack's hair when it was in there but it's better than nothing. Next time I'm going to part his hair & lightly sprinkle it ON the skin.This is so safe it's used in the silos where our grains are stored to control meal bugs so we eat some of it. Thought I'd pass this along as an alternative to the pesticides.. you can investigate for yourself
