Battling the Beetles
Adult Japanese Beetles typically show up sometime in early July and hang around through August. You’ll see them crawling or flying around plants like roses, grapes, and raspberries, where they chew on the leaves of these plants, leaving them with a lacy or skeletonized look, and eat the blossoms off of roses and other flowers. During this whole period, they eat, mate, and lay eggs on your lawn to start the cycle again next year.
There are a variety of sprays, lawn treatments, and traps to deal with these pesky insects at any stage of their life cycle!
Adult beetles are best physically remove them from your plants with a gloved hand, but don’t squish them! Squished bugs emit pheromones, which end up attracting more beetles…Take the captured beetles and toss them in a bucket of soapy water. Why soapy? Good question! The soap breaks the surface tension of the water so they cannot escape by crawling up onto the water’s surface and flying back out. After a day or two of collecting, you can toss the dead beetles out and start over if need be.
If you are looking for a less time-consuming approach, Sargent’s carries several sprays like Bonide’s Captain Jack’s Dead Bug, Beetle Killer, or Eight. These sprays can be used to kill the beetles, but pay attention! They can also kill beneficial insects like bees, so read and follow all directions on the label and don’t spray where bees are feeding!
Finally, you can use Beetle Traps to attract and kill beetles.
Beetle traps are controversial as they are shown to perform their task of LURING beetles to the trap quite well. They use pheromones to attract the beetles to them and these things really work! Because they LURE beetles in, you really do not want to hang these anywhere near the crops, trees, or flowers you’re trying to protect (OR near your neighbor’s plants either)! If you go this route, choose to hang your trap at least 30-40ft away from any plants that are important to you or others in the area. They do work very well to draw beetles in and kill them, so check your traps every few days to empty them before they get too full or too smelly. (It’s a container of dead bugs, it’s not going to smell pretty.)
