Are your recommended spray safe for plants? The beetles are both on my windows and on my outdoor plants.
Absolutely. As explained in this KUDZU BEETLE post, we have two kinds of concentrates you can use outside on your building and plants. Both are plant safe and will only target the target pest and not the plant itself. The CYPERMETHRIN will be the stronger of the two in that treatments will last a good 2-4 weeks. It also offers a repellency feature so this pest is likely to stay away from treated surfaces. The BUG PATROL will need to be applied more frequently and isn’t nearly as strong but as an organic option, quite effective on a wide range of tough, hard shelled insects like this beetle.
