I thought for sure when we moved in here that there were fleas. I was getting big welts on my lower legs, and nothing on my arms or chest. The welts would start about the size of a dime, then go up to the size of a quarter or more, then after a week they'd fade. husband wasn't being affected at all. You know how fleas are always in the grass, and there's plenty of grass here. So, we vacuumed and kept the dogs up to date with their flea products, and everything was good for about a week. Then we went to a charity thing that was outside on a lawn. And I had 4 big welts on my thigh when I woke up the next day. So, off we go to the home improvement store and get this spray for the grass to kill mosquitos, fleas, fire ants, every which thing. Yesterday was beautiful after 3.5 inches of rain the day before. So I'm out on the deck, and a little bit in the lawn, sprucing up the furniture. I was wearing my watch and the inside of my wrist started to itch. It was a small welt the size of a fingernail clipping. They always have a little hole where the bite is in the middle. Today it is the size of a quarter. It burns and itches so bad. I have been looking up fleas and remedies and killers and just don't know what I'm going to do with myself! I can't stay inside forever! Finally, today I looked up "bug bites" instead of "flea bites". I could be wrong, but I'm pretty sure it's chiggers. ARGH! I'm taking some benadryl and going to sleep! I can't stand this burning/itching/insanity!
