Garages are notorious places forcobwebs and spiders. This area has been treated. But there are quite a few egg sacs let me see if I can pull a few out for ya. Typical house spider egg sac has anywhere from four hundred to eight hundred baby eggs in it because these little white markings eventually within a year those egg sacs will hatch and even though the garages been sprayed it'll reinfest. If this was in your wall or up around the siding on the exterior of your house around your windows sill those baby eggs would be all over inside your home.
