Common household spiders are variable in color from tan to almost black female are generally 0.02 to 0.24 inch long while male are generally 0.15 to 0.19 inch long. They spin their web over lamps, in corner of baseboards, and in basement.
The black-and-yellow garden spider is found throughout Illinois. It builds a large orb web in grasses and weeds in open areas foyer in flower and vegetable gardens. The spider sits in the middle of the web with its head pointed toward the ground.
The black widow are easily identified because of their globular, shiny black abdomen with two reddish or yellowish triangles on the underside. Those reddish or yellowish triangles form a characteristic hourglass.
Spiders are adaptable arachnids that thrive in both outdoor and indoor environments. Outdoors, they are commonly found in landscape features, woodpiles, shrubs, under eaves, corners of sheds, and foundation perimeters where insects— their primary food source—are abundant. Indoors, spiders may occupy basements, attics, closets, garages, window corners, and behind furniture, particularly in undisturbed areas with available prey. Web-building species construct webs in low-traffic corners, while roaming species may wander throughout structures at night.
Most spiders are harmless and beneficial, preying on nuisance insects that may otherwise become pests. However, large populations indoors can create unsightly webs and silk debris, and in a few cases, species such as brown recluses or venomous orb weavers can pose a bite risk if disturbed. Spider bites are rare but can cause irritation or medical concern for sensitive individuals. Their presence may also indicate high insect activity or untreated entry points that allow other pests inside.
Common signs of spider activity include visible webs, silk strands across corners and ceilings, egg sacs, and occasional live sightings—especially in basements, attics, and undisturbed areas. Increased spider presence often correlates with high insect populations that serve as food sources. Spiders may be more noticeable during warmer months and in fall when they enter structures seeking shelter and prey.
Effective spider prevention begins with reducing the insect populations they feed on and closing off entry points. Seal cracks and gaps around windows, doors, foundations, and utility entries; install or repair screens on vents; and maintain weather stripping where needed. Reduce outdoor lighting that attracts insects, clear debris and woodpiles away from the home, and keep interior spaces tidy and free of clutter. Regular exterior treatments and targeted perimeter pest control help minimize both insect and spider activity, reducing the likelihood of spiders establishing themselves indoors.
