Eco system and “circle of life” aside, the worst insect with an active impact is the mosquito.
Why the heck are them things alive anyway? I was just on a vacation on the upper end of Vancouver Island, BC, Canada and the little suckers are everywhere! In the trees, on the dock in the cove, on the porch of the lodge, in the lodge, in the room…there was no getting away from them! The worst part was going to bed at night and having to douse myself in bug spray to keep from getting bit, sweating in bed from being afraid to expose skin, and not sleeping because you are afraid of getting bit and then itching non-stop for a week.
Nonetheless, I came home with bites and an itch that is truly distracting. Little buggers could go extinct as far as I am concerned and the world would probably be better for it, considering of all the diseases they carry. How much sickness and suffering would be solved if they just all died? A whole lot I think!
Anyway, what “life sucking” insect do you have a great disliking for?
