My Name is Nivia and I am new to the group. I am from Miami, Florida and I am raising Monarch caterpillars. I am having problems with the parasitic wasp. I have a tent where I am rearing the cats and a small tent in the greenhouse. The wasps are getting in an infecting the caterpillars. Any advise? I am bringing them in the garage at the 5th instar, but I was wondering if I make cages with veil materia which has very fine holes, could that be the solution.
I would appreciate any help at this point.
