Anyone in Florida have a suggestion for fighting mosquito infestation in my tortoise pen? I have a 100 lbs Aldabran and mosquitos swarm around her face constantly. I have mosquito magnets outside each end of the pen (3000 sq ft), and I have citronella torches along the perimeter, but cannot burn them constantly. This is the worst mosquito problem in the past 11 years! Is there any repellant that is safe to use on her neck and legs?
