Sticky glue traps are the most effective and widely available type of spider trap for home use. Unlike insect traps that rely on chemical baits or pheromone lures, spider traps work primarily through placement rather than attractants, since spiders don’t respond to conventional bait the way ants or roaches do. Understanding how these traps actually work, and where to put them, makes the difference between catching nothing and significantly reducing the spider population in your home.
Why Spider Traps Don’t Use Traditional Bait
Spiders are predators, not scavengers. They hunt live prey or wait for something to wander into their web. This means they won’t follow a scent trail to a bait station the way ants follow sugar or roaches follow protein. Most products marketed as “spider bait traps” are really sticky traps, sometimes with a mild attractant added, but the glue surface doing the capturing is what matters most.
Some traps include a light lure or an insect pheromone designed to attract the bugs that spiders eat, drawing spiders indirectly. In practice, though, placement along spider travel routes is far more important than any attractant. Spiders wander along walls, baseboards, and edges of furniture at night looking for prey or mates, and a well-placed sticky trap simply intercepts them mid-route.
Choosing the Right Sticky Trap
The University of Kentucky’s entomology department recommends flat sticky cards, the same type sold for mice and cockroaches, as an excellent tool for capturing spiders. The key detail: choose traps that are flat and thin, like a piece of sticky cardboard, without a raised perimeter edge. Raised edges create a lip that spiders can detect and avoid. A flat profile lets them walk directly onto the glue surface without hesitation.
You can find these at grocery stores, hardware stores, farm supply shops, or online. They’re inexpensive, usually a few dollars for a multi-pack. Avoid enclosed bait stations designed for roaches, since spiders are less likely to enter a boxed enclosure. Open, flat cards give you the best catch rate.
Where to Place Traps for Maximum Catches
Spiders, like most crawling pests, prefer to travel in dark areas along edges rather than crossing open floor space. Texas A&M’s AgriLife Extension recommends placing sticky traps in direct contact with a wall, with the two open ends of the trap running parallel to the wall surface. This orientation makes it easy for spiders to walk straight onto the trap as they follow their natural path along the baseboard.
The best locations include:
- Along baseboards in rooms where you’ve seen spiders or webs
- Inside closets and storage areas where clutter provides hiding spots
- Behind furniture that sits against walls, especially bookshelves and dressers
- Garage walls and along the edges of the garage floor
- Near entry points like doors, windows, and utility pipe openings
- Under beds and in corners of rooms that stay dark and undisturbed
Space traps at least 5 to 10 feet apart in areas where spiders are likely to travel. More traps in a problem area will intercept more spiders, but spreading them out gives you better coverage and helps you identify which parts of the house have the most activity.
Trapping Brown Recluse Spiders
Sticky traps are especially useful if you’re dealing with brown recluse spiders. Recluses are nocturnal wanderers, and males in particular roam long distances at night searching for mates. This makes them highly vulnerable to well-placed glue traps. In fact, sticky traps are one of the primary tools pest control professionals use to both monitor and reduce brown recluse populations indoors.
For brown recluse control, focus trap placement in storage areas, along garage and indoor walls, and in any cluttered spaces like attics, basements, or spare rooms with boxes. These spiders avoid open, well-lit areas, so traps tucked into quiet corners will outperform traps placed in the middle of active rooms. Checking traps weekly also helps you gauge how severe an infestation is and whether your efforts are working.
When to Replace Your Traps
Sticky traps lose effectiveness over time as dust settles on the glue surface, reducing its stickiness. Replace traps when they’re visibly dusty, full of caught insects, or have been down for more than a month or two. In dusty environments like garages and basements, you may need to swap them out more frequently. A fresh trap with clean adhesive will always outperform one that’s been sitting for weeks.
Keeping a simple log of what you catch on each trap can tell you a lot. If one location consistently catches spiders and another catches nothing, you can redistribute your traps to focus on active zones. This turns the traps into a monitoring system, not just a control method.
Pets, Kids, and Non-Target Catches
Sticky traps are non-toxic, which makes them safer than chemical sprays in homes with children and pets. But they can catch things you didn’t intend to trap. Cats and small dogs can step on them, and curious toddlers can pick them up. Place traps in locations pets and kids can’t easily reach: behind heavy furniture, inside closets with closed doors, or tucked under appliances.
If a pet does get stuck, don’t try to pull the trap off directly, as that can damage fur or skin. Gently massage baby oil or vegetable oil into the area where the adhesive contacts the fur, working slowly until the trap releases. Wipe the oil off with a towel afterward. For small animals like lizards or mice that get caught accidentally, the same oil technique works. If the animal appears injured, contact a wildlife rehabilitation center rather than trying to treat it yourself.
Combining Traps With Other Control Methods
Sticky traps work best as part of a broader approach. They’ll catch wandering spiders, but they won’t address the conditions that attract spiders to your home in the first place. Reducing clutter eliminates hiding spots. Sealing gaps around doors, windows, and utility lines cuts off entry points. Switching outdoor lights to yellow or sodium vapor bulbs attracts fewer flying insects, which means less prey drawing spiders to your home’s exterior.
Vacuuming webs and egg sacs directly removes spiders that traps might miss, particularly web-building species that tend to stay in one spot rather than wander. A vacuum with a hose attachment can reach ceiling corners, window frames, and the gaps behind appliances where spiders like to set up. Combining this with a grid of sticky traps along your walls gives you coverage against both the stay-put web builders and the active hunters that roam at night.
