The Catchmaster Fruit Fly Trap Glueboards are banana scented and are used for monitoring and trapping fruit flies. Use the Catchmaster Fruit Fly glueboards for monitoring activity and to help determine the source of your issue. The board can be folded into a cylinder shape for monitoring drains, or a U shape to cover certain areas for monitoring, or placed flat on almost any surface.
They work great at catching crickets and spiders in our vacation house. I lay them out flat and they attract the bugs. I will place them in different ares where you won't step on them and it is amazing what they attract and catch.
I highly recommend them.
I found I had to spray balsamic vinegar on the traps or the flies would not go onto the board. There is already a faint smell on the boards so they are baited but the fruit flies I was dealing with were not attracted to the bait. I may have had too high an expectation of the glueboards but found that 1/3 to 1/2 of the flies went onto the boards and the rest had to be manually killed. The company mailed them out very quickly and their service was good. I did not approach them about a refund for the unused boards because I think they will help with the problem we seem to have at the end of every Summer.
Had to pour wine or vinegar on cards to attract any of the hundreds of fruit or drain flies we've been contending with, and even then they weren't 1/50th as effective as a cup of cider vinegar with a drop of soap in it.
