Various stages of young Boxelder Bug nymphs.
Pretty much harmless to humans, animals, and most plants. They will munch down on various things in their youth stages (apple, plum/peach, ash, some elms), but rarely enough to do massive damage.
Agree. Boxelder.. But I disagree on the harmless. The same year they showed in numbers was the same year we lost our raspberries....which were their preferred hang out.
You can kill them with dish soap mixed in with water, using a spray bottle. If you have a larger amount, then you can use a hand sprayer and just cover the general area where they are.
It kills them pretty fast. Not sure if they drown or just react to the dish soap, but you can kill the nymphs and adults like this.
If I remember correctly, they like to hang out with female maple trees, so you or a nearby neighbor probably has one of these.
Thank you. They were in the ivy along the fence. I will not worry about them for now.
