I have 18 balls 3 red eared sliders and a leopard gecko. I wish I had more than 1 day notice!..and I live in northern new hampshire, its not like I can just move my racks outside this time of year. my property manager is pretty cool though, maybe I'll explain to her the situation and ask her not to spray near the animals. the only place we've had spiders is in the bathroom. and personally I don't mind them.
