Spiders are among the most common pests found in Chicago homes, and while most species are harmless, their presence is unsettling and their webs are a constant nuisance. Common house spiders, cellar spiders, and wolf spiders are typically more of an annoyance than a threat, but Illinois is also home to medically significant species like the black widow and, in some regions, the brown recluse, whose bites require prompt attention. Because spiders are predators, an indoor spider problem is almost always a sign of an underlying insect problem — spiders go where the food is. Chicago Pest Control treats both the spiders and the prey that attracts them, delivering lasting results rather than a temporary knockdown.
Our experienced technicians begin by inspecting your property to identify the species present, locate harborage areas, and find the entry points spiders use to get inside. Many spiders nest in cluttered storage areas, around exterior lighting, and in the gaps where utility lines enter the structure. We then de-web eaves, corners, and entryways and apply targeted treatments to cracks, voids, and the perimeter where spiders travel and hide.
We use family- and pet-safe products and focus applications where spiders actually live rather than spraying indiscriminately. The result is fewer spiders, fewer webs, and a home that stays comfortable. For a free inspection and a custom treatment plan anywhere in Chicago, IL, call (773) 309-3733 and one of our technicians will help you right away.
When to Call for Spider Control in Chicago
Spotting the early warning signs gives you the chance to act before the situation spirals into something far more expensive. Here are the most common indicators that it's time to call a professional:
- Webs appearing repeatedly in corners, eaves, or window frames
- Spiders spotted regularly indoors, especially in basements or garages
- Egg sacs (small silken balls) tucked in corners or undersides
- Black widow webs that feel unusually strong and irregular
- Shed spider skins or droppings near baseboards and sills
- An increase in flying insects that draws spiders indoors to feed
- Bite marks or skin reactions suggesting a venomous spider

Why Professional Spider Control Matters
Store-bought sprays kill the spiders you can see, but they do nothing about the egg sacs hidden in voids or the insect population that keeps drawing spiders into your home. A single black widow or brown recluse egg sac can release hundreds of spiderlings, so missing even one undoes your efforts. experienced technicians know where each species hides, how to remove egg sacs safely, and how to treat the cracks and voids that DIY products never reach.
There is also a real safety dimension. Black widow and brown recluse bites can cause serious medical reactions, and homeowners often disturb these spiders in woodpiles, storage boxes, and dark corners without realizing the risk. Professional technicians use proper technique and protective equipment to handle dangerous species, and they treat the broader insect ecosystem so spiders lose their reason to stay. That combination of safety and source control is something retail products simply cannot match.
Our Spider Control Process
Every visit follows a step-by-step method refined over years of hands-on experience. Here's a look at each step our Chicago Pest Control team takes:
Inspection & Species ID
Our technician identifies the spider species present, locates webs, egg sacs, and harborage points, and checks for dangerous black widows or brown recluses to determine the right treatment approach for your property.
Web & Egg Sac Removal
We physically de-web eaves, corners, doorways, and exterior surfaces and remove accessible egg sacs. This eliminates existing populations and makes follow-up treatments far more effective at preventing return.
Targeted Treatment & Prey Reduction
We apply pet-safe products to cracks, voids, and the foundation perimeter while treating the insects spiders feed on. Cutting off the food source is the key to keeping spiders from coming back indoors.
Ongoing Protection
We seal entry points, recommend prevention steps, and set up scheduled monitoring. Recurring visits keep the perimeter treated and the prey population down so spiders have little reason to return.
Not Sure What You Need?
We provide honest advice and free inspections on all spider control work.

Taking preventive measures can help you avoid costly pest problems down the road. Here are our expert recommendations:
- Reduce outdoor lighting or switch to yellow bulbs that attract fewer insects spiders feed on
- Clear webs, woodpiles, and debris away from the foundation and exterior walls
- Seal cracks around windows, doors, and utility penetrations where spiders enter
- Keep storage areas tidy and store items in sealed plastic bins instead of cardboard
- Vacuum regularly in corners, under furniture, and around baseboards to remove webs and eggs
- Control other insects, since fewer prey means far fewer spiders inside your home
- Shake out shoes, gloves, and stored clothing that has sat undisturbed in garages or closets
DIY vs. Professional Spider Control
A homeowner can manage the occasional pest, but serious infestations call for the products, equipment, and know-how only a pro brings. Consider the following comparison:
| Factor | DIY Approach | Professional Service |
|---|---|---|
| Species ID | Hard to tell harmless from dangerous | Trained to identify and handle venomous species |
| Egg Sacs | Sacs survive and hatch hundreds more | Sacs located and removed before they hatch |
| Prey Source | Food insects keep drawing spiders in | Prey reduction removes the reason spiders stay |
| Hidden Areas | Voids and cracks go untreated | Treatment reaches voids, cracks, and harborage |
| Safety | Risk of bites disturbing nests | Proper gear and technique reduce bite risk |
| Lasting Results | Spiders return within weeks | Ongoing protection keeps spiders out |
