I have been using this brand of Insect traps for about twenty years. Here I have shown just the refills. These glue boards fit into a plastic unit that plugs into the wall. The units now have a small energy efficient LED bulb, whereas before they had a chandelier bulb. Locally, the only place I can find them is at Ace Hardware. They are worth driving out of my way to buy them.
In my experience here in Florida, they are really effective in flea control and somewhat effective in trapping other kinds of insects. They are part of my arsenal of toxic-free pest control measures inside my home. If I start to loose the battle with the bugs, I will drive out to the university extension service toting my specimen that I have trapped in clear package wrapping tape for identification. They will use their microscope, if needed, and provide me with a free written plan that I insist has no harmful effects for people, animals, or the environment. All you need to do is ask; of course, you need to know that this service is available. This keeps me blogging.
I hope this post can save you my reader or a precious pet, elderly person, or a child from the harmful effects of pesticide poisoning. Please pass this advice on to everyone you know.
