If you have a pest problem outdoors, the sticky traps are temperature-resistant and waterproof, so you can easily use them outside. The traps come in a variety of shapes like butterflies, birds, and flowers, too. “Thanks to my son’s science fair project with fruit, we developed a small fruit fly problem in May. I’ve been trying to get rid of them for two months using home remedies, to no avail,” this reviewer said. “I got these adhesive traps and within 12 hours, they caught almost all the fruit flies. I’m sure by the end of the weekend, I will have solved my two-month fruit fly issue, cheaply and without chemicals. Don’t hesitate if you have fruit flies!” One shopper wrote, “These work amazingly well. If you have fungus gnats they are a must-buy. I had such an infestation, [and] it was driving me bonkers. Three hours after I put these traps in my plants, there were just a few gnats still flying around. The rest of their brethren were stuck fast to the traps. I even used one in my kitchen around the produce we’ve been hauling in from our garden and quite a few fruit flies got stuck to it. Well worth the few bucks they cost.”
