Wasps Attacking Monarch Cats
I have seen at least two species of wasp attack and kill my Monarch cats. I have also found a chrysalis that had been gnawed into and cleaned out.
Does anyone know any effective counters to these little bastards? I can't poison them, obviously. Is there something I can plant that will keep them away but not bother my cats? Not just Monarch cats, but they are my main variety by far.
