Been a while since they were this bad!
Swarms of the evil, biting little suckers, all day long - even my eyeballs are itchy

Between the flea & tick meds for the (indoor) dog & cats, and wiping mosquito & fly repellent on the horses daily, I'm concerned that some residue may find it's way into my tank.
I'm careful about scrubbing after applying this stuff, and use gloves around the tank, but I still worry...
Should I ban the dog and cats from the room the tank is in?
