Outdoor lights and spiders.
Porch lights draw insects, and insects draw spiders. Yellow bulbs attract fewer bugs. Motion-sensor lights help too.

Garages collect webs, boxes and insects. Store things in sealed bins off the floor. A door sweep and a sticky trap by the door help.

When spiders are busiest around Newark
Yellow sac spiderlings overwinter and mature in May-June; they enter structures through faulty screens, loose-fitting doors, vents, utility lines and plants brought inside (Rutgers NJAES).
Rutgers NJAES: 'Spiders, including widow spiders and recluse spiders, are generally timid creatures. In fact, spiders seldom bite people.' Bites 'usually result from spiders being accidentally trapped against the skin or being handled.' Black widows shelter under stones, firewood piles, decks, hollow stumps and rodent burrows, and indoors in garages, basements and crawl spaces.
