Spiders are in your house because food is. Every spider problem is also an insect problem, which is why spraying webs in the corners never lasts. Our approach reduces the spiders you see, removes the ones that matter, and cuts off the supply that keeps drawing them in.
Spiders Common in Indiana Homes
Common House Spiders and Cellar Spiders
The cobweb builders in ceiling corners, basements, garages, and window frames. Harmless, but the webs and egg sacs multiply quickly and are the number one reason people call about spiders.
Wolf Spiders
Large, hairy, fast, and alarming on a basement floor at night. They hunt rather than build webs and come inside in fall looking for warmth. They are not aggressive and their bite is not medically significant, but nobody wants one in the laundry room.
Brown Recluse
Present across Central and Southern Indiana. Light brown, about the size of a quarter with legs, with a violin-shaped mark behind the head and six eyes instead of eight. They live in undisturbed places: storage boxes, closets, attics, behind baseboards, inside stored shoes and clothing. Their bite can cause a serious wound, and they are the spider we take most seriously.
Black Widow
Uncommon in Indiana but present, usually outdoors in woodpiles, under decks, in meter boxes, and in cluttered garages. Shiny black with a red hourglass underneath. Their bite is a medical concern.
Signs You Have More Spiders Than Usual
- Webs rebuilt within days of being cleaned away
- Egg sacs (small white or tan silk balls) in corners, window frames, or under furniture
- Spiders in bathtubs and sinks, which usually means they are coming out of wall voids or drains at night
- A flying insect problem near lights and windows, which is what the spiders are there for
- Sticky glue boards or corners in the basement filling up with spiders and prey
Think you have brown recluse?
Do not reach into stored boxes, shake out clothing and shoes that have been sitting, and put a glue board in the closet or attic where you saw it. Bring us the spider or a clear photo and we will confirm the ID before anyone panics.
How We Treat Spiders
- Identify what you have. Recluse and widow treatment is different from a cobweb spider problem. We confirm the species with monitors and inspection before treating.
- Remove webs and egg sacs. De-webbing eaves, soffits, window frames, and corners removes the current generation and the next one.
- Treat harborage and entry points. Targeted applications around the foundation, window and door frames, garage door edges, and utility penetrations, plus dust in the wall voids and attic spaces where recluse spiders live.
- Reduce the food supply. Our perimeter treatment cuts down the flies, gnats, crickets, and other insects that spiders are hunting. Fewer insects, fewer spiders.
- Monitor. Glue boards in closets, garages, and basements tell us and you whether the population is dropping, and they catch recluse spiders that would otherwise never be seen.
What You Can Do
- Switch exterior bulbs to warm LED or yellow bulbs. Fewer flying insects at the porch light means fewer spiders on the porch.
- Get storage off the floor and into sealed plastic totes instead of cardboard. Recluse spiders love cardboard flaps.
- Seal gaps around windows, doors, and where pipes enter. Door sweeps alone stop a lot of fall wolf spider traffic.
- Keep firewood, leaf piles, and lumber away from the house and wear gloves when moving them.
Keeping Spiders Down All Year
Spiders peak indoors in late summer and fall. The Comprehensive plan includes de-webbing and a perimeter treatment on every quarterly visit, which is the only reliable way to keep them down in a home on a wooded lot or near water. Single Session treatments are available for a confirmed recluse or widow problem.
Spider Control Questions
Yes. They are established across Central and Southern Indiana and are found in homes, especially older ones with attics, crawl spaces, and lots of undisturbed storage. Most bites happen when someone puts on clothing or reaches into a box where a spider is hiding.
Late summer is when most spiders reach adult size and mate, and cooling nights push hunting spiders like wolf spiders indoors. It is also when their prey moves inside. A fall perimeter treatment and de-webbing takes care of most of it.
Spiders walk on the tips of their legs and do not groom the way insects do, so contact sprays are less effective on them than most people expect. Removing webs, treating where they hide, and reducing their food supply works far better than spraying the spider you see.
No, and you would not want to; spiders eat a lot of the insects you like even less. The goal is to remove the dangerous species, keep the population low, and stop the webs from taking over.
A confirmed brown recluse or black widow problem usually gets a targeted Single Session treatment with monitoring. General spider pressure is best handled by the quarterly Comprehensive plan, since spiders come back every season.
