Yes, it needs to be followed up - one treatment is not enough to bump off the little horrors. They must be so irritating to the poor snake and even more so if you've got an itch and can't scratch it![]()
Since I treated the snake and his viv with Frontline, I've only seen two live (just) mites. On looking at one under a magnifying glass, it was obviously on it's way out - it was falling over it's own feet. I helped it on its way. I squished it - and same with its pal.
I got my rescue Ball from a rescue centre. As soon as I discovered he had mites, I phoned them and told them. It wasn't a heavy infestation - there wasn't that many that I could see, but enough to treat the problem immediately and hopefully nip it in the bud before the little 'bs' spread.
