I had my own scare with a tick bite on my thigh. Two days after tick was removed a four inch in diameter lesion appeared. Physician placed me on antibiotics for a few weeks and lesion resolved. It was a little frightening. A few weeks ago my grandson and I went fishing. The redbugs ate my rear end up. The poor boy clawed his little goober raw. As far as annihilation I think ticks and redbugs are immune to pesticides, pole reversal solar flares, climate change and fire ants. But I feel a vaccine would be a good thing for those who frequent the outdoors.
