I would remove all reptiles, amphibians, and invertebrates as they react badly to insecticides. Make sure all the lizard and frog tanks are either wrapped in plastic or in a tightly sealed trash bag so that the fumes can't enter and settle.
If your snakes are in a rack you can run the water bowls and hides through the dishwasher, wash the tubs, and wipe the rack(s) with a damp cloth to remove the chemicals before you put the snakes back.
