Cheyenne some how got fleas. Probably from the strays outside we feed. We gave him a treatment that seemed to work but, for the house I seen this light trap that looked good. So far we got about 6 fleas in it the first day. I was told to sprinkle fine salt in the carpet as it would dry out the fleas and kill them. Someone said to make my own trap with water and Dawn dishsoap. But I read that could make Cheyenne very sick if he was to drink it. So the light seems to be the safest way. And Cheyenne likes the light............
