Query: Have 6 of them, and it is a slaughter for those fleas..

Best trap around, I already had 4 of them and decided to get two more plus the re-fill, They work great and really do keep the fleas under control. I put them under my bed, though the item is a little tall and hit against the frame, I just removed the top then re-assemble under the bed. Anyway you do have to place them well and also make sure it's dark (no other night lights (you wont need them with this). If you don't like fleas then you have to try this product. Don't purchase just a couple, purchase at least 6 for the average home.
