First, I wish your brother a full recovery from Lyme Disease.
I'm 67 years old and a few medications came with the years. Your question got me thinking, we put a 30 day flea and tick killer on the cats and they sometimes sit on my recliner. That stuff used to work so well that we only had to put it on the dog and the cats didn't have fleas or ticks. The dog died a while back. This year, we're putting the flea and tick killer on both cats but they're still scratching. It's hard to believe a small transfer from two cats is killing ticks on me, especially since, I'm staying out at the farm and seldom around those cats. Maybe I should give the cats some cholesterol medicine.
For years I've occasionally gotten a tiny tick attached to my miserable old hide. I think they're called deer ticks as often as not, by the time I find them, they seem to be dead. Does anyone know, WHY THEY'RE DEAD? I'm not complaining about it, I just wish they'd die before they inject the itch serum.
I'm in my 50's. Have multiple ticks on my body over the years which were removed, but NONE have ever been dead.
Rubbing alcohol kills them pretty well. Keep a pill bottle full of the stuff and whenver one comes off, they go into the bottle. You generally want to keep them for while to esnure you haven't gotten anything, and by bad chance you catch something, you want to have the actual tick on hand that caused the problem IMO.
