I was wondering if I should (carefully) spray the outsides of my container with some kind of repellant. Perhaps I won't worry about it until/unless I see a roach.
We've never had a problem with roaches around our FW top-off supply, but if you feel strongly about it, get a "roach motel" or some kind of bait...do NOT spray any kind of pesticides around your tank or water supply. ;)
