When my in/outdoor ***** started scratching I got some Hartz One-Spot
for her. She kept scratching more and more so after 2 weeks I took a
flea comb to her. I was very surprised to comb out about a dozen
fleas.
After rereading I found out One-Spot don't kill adult fleas but just
stop young ones from developing. So my ***** was picking up adults
outdoors while I thought she was protected. Guess I'm going to have
to douse her with some strong poison flea killer to give her relieve.
Mean while I'll keep working with the flea combl.
