Wasps In Zebra Grass Plant

Question

I live in Germany, right now it’s pretty hot and a little humid. We usual get a few wasps in the summer, but I’ve recently noticed a lot of them crawling amongst the leaves of my zebra grass potted plant on the balcony. They aren’t going down into the earth, just walking around on the leaves. The grass plant is also showing signs of distress, the leaves are browning. Any idea what’s going on?

Answer 1

Many wasps hunt other insects. They are good at controlling many caterpillars. The presence of them would indicate, to me, that you have another insect issue at hand. The damage can lead to infections, and crop loss.

Most broad spectrum pesticides and organic options will work here.

Answer 2

Thanks for your help. I looked again and saw a few ants but the wasps don't seem interested in them at all! ??‍♀️
