Yeah if you can ahold of some provent a mite wow does that stuff work wonders. I only use it around the base of my racks, along walls and in doorways. It has residual affects for a few weeks. Ive seen a spider walk across an area I sprayed and just keel over. Spiders are hard to kill too. A good flea and tick powder along walls, enclosure stands etc, will also kill them and keep them from getting into the snakes enclosure. The ant baits will be good long term as they take the poison back to the colony.
