I got the Victor Flea trap years ago and used it in my dog grooming shop. When I moved to the coast and had the warm weather nearly all year, I started having flea problems again even with all the vet recommended products for my animals. I got these refills for the trap and leave it on all the time. That way I can make sure I do not get an infestation. It works great and does draw the fleas to the light. It's very strong adhesive traps them there. I would recommend this to anyone with a pet and the possibility of fleas. Great value too.
