Ants eating eggs and cats...
I have alot of milkweed for my butterflies and raise Monarchs and Swallowtails. I never use insecticide and 'hand pick' the pests off like red/black beetles and ladybugs take care of the aphids. Have not had a problem with ants but if I did I would glob petroleum jelly near the base of the plant. They won't be able to crawl up the stems. I use this on my shepherd hooks I hang my hummingbird feeders cause the ants love the sweet liquid. I spread a thick one inch wide glob and have since not had the problem.
Thanks for the tip! I wouldn't think the petroleum jelly would do anything to the plant...sounds like a good idea. Anybody tried this??
