Ack! I've got red bugs again. The good thing is that its on my arm this time. Sorry this is not about their evolution, but could anyone help with this problem? I was out clearing vines and foilage with a machete when I must have come into contact with them. What house supply (rubbing alcohol?) should I use for these things? Will they die or will they become dangerous? I don't even know if they are actually called "red bugs". They are bugs (obviously here in Florida) that dig under the skin and cause greif to their host. They look like red bites.
