We live in the Rio Grande Valley in Deep South Texas. This past year, the valley has had one of the worst flea infestations in years. We have two small dogs and one cat; the dogs go outside 2-3 times a day; the cat stays inside. All animals are given medication against fleas and ticks (Comfortis) and this medication keeps them critter free; however, some fleas still manage to get in the house leading me to believe humans bring some in. We have one Victor Flea Trap under a chair in the living area and one under a nightstand in our bedroom; they really work. In addition the traps use a nightlight and consequently, they provide a comfortable light should one need to get up during the night. I highly recommend this product.
