are you sure they're spiders and not spider mites? if they are spiders, leave em be. they won't hurt your plant...just the opposite in fact. but i'd do my best to make sure they're not mites...look for tiny white spots on the leaves and pinhead size eggs on the undersides. if clear you should be fine.

good luck...gettin close!
