Two of these very traditional flycatchers have catched being invaded by over 200 fruit flies in two days out of the kitchen. Then we had the rest of critters. The material is virtually odorless and glued like the plague - also on the hands! For assembly and disassembly necessarily put disposable gloves and throw away afterwards, otherwise it is an all the time busy with handwashing. Adhesive residue on furniture can be easily scrub the way again with salad oil. Total recommended resources and to quite inexpensive. I will use it again next summer when the fruit fly time.
