I'd use a shop-vac to get rid of the visible infestation and a residential spray insecticide to keep them away. Clean out the garage. There are perimeter insecticides that may help if the problem continues . Keep in mind, however, that your arachnids (not spiders, though) eat insects.

They are harmless. I suspect that possibly it is a mating season or some other biological reason for their gathering as that is not typical behavior. In other words, it won't last long, I'm thinking.

That said, as Tony said, a residual spray will work well on them. Buy a concentrate insecticide that you mix with water and apply with a compressed air sprayer. Probably won't even need the maximum rate. Sometimes the box stores, other hardware stores, and farm supply stores, depending on your state, will carry them. I don't know the brand names, but look at the active Ingredients for names such as : deltamethrin, Lambda cyhalothrin, cyfluthrin, bifenthrin. There are others, but any of these will work well.

As long as they are not inside, I would leave them alone. They are doing more good than harm.
