It looks like my mail won't be delivered the next couple of weeks. Twice a year my Milkweed plant is visited by rather large wasps. I have never experienced any problem with them and I have made pictures of them and get really close. They look scary I suppose if you are afraid of insects but all they do is drink the nectar and fly around the plant. The lady who delivers my mail said that I should have them exterminated. I opted to have to pick up my mail at the Post Office for a couple of weeks.
