| Insecticide for Red Wasps
Does anyone know of an insecticide that will kill wasps and hornets and is safe for use around koi? Or can anyone suggest another method to remove them?
We have been plagued with Red Wasps since installing a koi pond last year. I just found that the nest is in the hollow underbelly of an ornamental heron in the middle of the pond. Obviously, moving the heron runs the risk of nasty stings; using a soap film fogger isn't good for the pond or fish, and most insecticides are harmful.
Any ideas?
Also, I noticed one of the wasps had fallen into the water the other day and was so waterlogged could not dry its wings and fly. The koi were interested in the movement but none made a move to eat it. I'm new to koi, and want to know if they are instinctively programmed not to eat something potentially harmful like that. I'm assuming eating a living hornet would produce some nasty stings in the mouth and gullet. |
