6 Best Spider Traps For Small RV Storage Nomads Swear By

You slide open the pass-through storage door after a few weeks, reaching for your leveling blocks, and your hand brushes against a sticky, unseen web. It’s a classic RV moment, a reminder that you’re never truly alone in your rig. For those of us living or storing our homes-on-wheels, keeping eight-legged tenants at bay is a constant, low-grade battle for peace of mind.

Why Spiders Love Your RV’s Hidden Spaces

Spiders aren’t drawn to your RV because it’s dirty; they’re drawn to it because it’s a perfect fortress. Think about it from their perspective: it’s a collection of dark, tight, undisturbed spaces. The area behind your water heater, the corners of your storage bays, and the void under the dinette seats are ideal real estate for them to build a web and wait for prey.

This is especially true when your rig is in storage or parked for an extended period at a campsite. The lack of daily movement turns your RV into a stable, predator-free environment. Insects find their way in through tiny gaps in slide seals or the underbelly, and spiders simply follow their food source.

It’s a game of opportunity. Your RV offers countless nooks and crannies that mimic the natural shelters spiders seek out. Understanding this is the first step to effective control—it’s not about deep cleaning, it’s about strategically disrupting these safe havens.

Terro Spider Traps: A Simple, Effective Solution

When you just need something that works without fuss, Terro traps are the answer. These are incredibly simple, foldable cardboard glue traps. You peel off the protective paper, fold it into a tent, and place it where you need it. That’s it.

Their effectiveness comes from their dual-action nature. They catch spiders, of course, but they also catch the other crawling insects that spiders hunt. By placing these in storage bays and under cabinets, you’re not just trapping the predators; you’re removing their food supply. For a small, enclosed space, using a non-toxic, pesticide-free solution like this is a massive advantage.

The main tradeoff is that they are disposable and require monitoring. In a high-traffic area, the glue can get covered in dust, rendering it useless. Their simplicity is both their greatest strength and their only real weakness. They are a fantastic first line of defense for interior spaces.

Catchmaster 72MAX: Bulk Traps for Full Coverage

Sometimes, the best strategy is overwhelming force. The Catchmaster 72MAX isn’t fancy, but it offers a huge quantity of large glue boards for a low price. This is the workhorse option for anyone who needs to cover a lot of ground, especially when putting an RV into long-term storage.

With a bulk pack, you can afford to be generous. Place one in every single cabinet, two in the pass-through, one under each dinette bench, and another behind the toilet. This saturation method leaves very few safe pathways for spiders to travel without getting stuck. You’re creating a minefield of sticky surfaces in all the places they love to hide.

These are purely functional tools. They are unscented, unlured, and rely entirely on spiders wandering onto them. They aren’t discreet, but in the unseen spaces of an RV, that hardly matters. For comprehensive coverage on a budget, nothing beats buying in bulk.

Mighty Mint Spray: A Natural Repellent Barrier

Traps are great for catching what’s already inside, but a repellent spray helps prevent them from getting in. Mighty Mint is a popular choice because its primary ingredient is peppermint oil, a scent spiders despise. It’s a completely different approach—you’re making your RV inhospitable, not just setting traps.

The best use for a spray like this is creating a perimeter defense. You’re not spraying it all over the interior; you’re targeting entry points. Lightly mist around the edges of slide-outs, the frames of storage bay doors, your stabilization jacks, and where your power cord and hoses enter the rig. This creates a "scent fence" that encourages spiders to look elsewhere.

The downside is its lack of permanence. A heavy rain can wash it away, and the scent fades over a couple of weeks, requiring reapplication. It’s a maintenance task, not a one-time fix. But it’s non-toxic, safe for pets once dry, and makes your storage bays smell fresh. Use it in conjunction with interior traps for a powerful one-two punch.

EarthKind Stay Away: Scent-Based Pouch Defense

For a set-and-forget repellent, EarthKind’s Stay Away pouches are brilliant. These are small mesh sachets filled with a blend of essential oils, like rosemary and lemongrass, that slowly release a scent spiders and other pests find offensive. They offer a passive, long-lasting deterrent perfect for enclosed spaces.

The beauty of these pouches is their placement versatility. You can toss one into a drawer with your linens, place one in the back of a kitchen cabinet, or tuck one into the control panel compartment. There’s no sticky mess and no wet spray, making them ideal for sensitive areas. They typically last 30-60 days, making them perfect for protecting your rig while it’s in storage.

Be aware that the scent can be potent in a very small, enclosed living area. Some people love it, others find it overwhelming. They also only repel—they won’t do anything about a spider that’s already built a home inside. Think of these as a "No Vacancy" sign, not an eviction notice.

Harris Spider Traps: Lured for Better Captures

Most basic glue traps rely on luck. Harris Spider Traps try to improve those odds by including a lure. While the exact formula is a trade secret, the idea is to subtly attract spiders, drawing them onto the sticky surface more proactively than a plain, unbaited trap.

This makes them a great choice for targeted problem-solving. If you consistently see spiders in one specific area, like near the water pump or in a particular corner of the bedroom slide, a lured trap can be more efficient. Instead of waiting for a random encounter, you’re actively encouraging the spider to investigate.

You’ll typically get fewer traps per dollar compared to a bulk option like Catchmaster. The decision comes down to strategy: do you want to blanket the entire RV with basic traps, or place a few higher-potency traps in known hot spots? For many, a combination of both is the most effective approach.

Trapper Insect Trap: Discreet, Professional Grade

If you need a trap for a more visible area, the Trapper Insect Trap is a fantastic, low-profile option. These are the kind of traps pest control professionals often use. They can be used as a flat board or, more effectively, folded into a covered box shape.

The covered design is a huge advantage in an RV. It keeps the sticky surface free from dust and debris, prolonging its life. It also hides the captured insects from view, which is a lot more pleasant than looking at an open glue board by your entryway. You can slide them under the edge of a fridge or a sofa, and they practically disappear.

While they may cost a bit more per unit, their discreet design and longer effective lifespan make them a worthy investment for the main living quarters. They provide professional-grade trapping without making your home look like a science experiment. Use the big, cheap traps for the basement and save these for inside.

Strategic Trap Placement in Your Small RV Space

The most expensive trap in the world is useless if it’s in the wrong spot. Spiders are predictable. They travel along edges and seek out dark, quiet corners. To beat them, you have to think like them.

Effective placement is everything. Focus on the perimeters of rooms and storage areas, where walls meet floors. This is their natural highway system. Placing a trap in the middle of an open floor is a waste of time and money.

Here are the must-have locations for traps in any small RV:

• In the corners of every exterior storage bay, especially the pass-through.
• Under sinks, right where the plumbing pipes come through the floor or wall.
• Behind the sofa and tucked under the edges of dinette benches.
• Near the four corners of your slide-outs, on the interior floor.
• Inside utility compartments that are accessed infrequently, like where the water pump or converter is housed.

Ultimately, a multi-layered defense is best. Use repellent sprays on the outside to deter new arrivals and a variety of traps on the inside to catch the ones that get through. Check them every few weeks, replace them when they’re full or dusty, and you’ll reclaim your space.

Keeping spiders out of your RV isn’t a one-time event, but a simple, ongoing process of strategic defense. By understanding their habits and using the right tools for the job, you can ensure your tiny home remains a sanctuary for you, not for them. It’s about consistency, not complexity.
