How can I safely prevent monarch caterpillars from going into a certain area during their wandering phase?
As you know, my grandmother's milkweed had two batches of monarch caterpillars. The first batch I had 6 but only 4 made it and on my last batch I had 4 caterpillars but only 1 made it. The 5 caterpillars that I never knew what happened to them may have gone into the grass and vegetation that is next to the milkweed were they may have become way to camoflauge were they are impossible to spot or got eaten by ants and other predators that live in the vegetation.
Is there a way to prevent the caterpillars from going into the grass and vegetion during their wandering phase without using a mesh netting or harming other creatures living in the vegetation? I am planning to get rid of the grass and weeds but I am waiting till the weather gets cooler since it is hot right now and there are no caterpillars nor eggs on the milkweed at this moment. But any advice on preventing the next batch from going into that area is much appreciated.
