Do you know their scientific name, Rice? I do want to test dumping some of them in the water and making sure the fish will eat them. We have a somewhat similar bug present here also, the brown marmorated stink bug (Halyomorpha halys) that defends itself by tasting too bad to eat. It sucks on fruit. It’s causing a huge amount of fruit damage.UV lamps hung out over your ponds and feed the fish. That is what I do.
