Have a Spider in Your Gas Grill? Get tips and expert advice on how to identify and solve spider-related burner blockage issues in your gas grill.

If you find that your gas grill’s flames are not as strong as they used to be, you may have a spider in your gas grill.

Unwanted guests crashing your barbecue is never fun. It’s even worse when those guests have eight legs and decide to move into the grill itself!

Spiders and other insects creating nests in gas grills is a fairly common problem. After all, your grill is a pretty attractive option for any outdoor critter looking to build a home.

Thankfully, this issue is one that’s easy to prevent and pretty simple to solve, even if it does happen.

In this article, we’ll share why spiders and insects are so interested in your gas grill in the first place, how to prevent them from getting inside, and what to do if they are successful at sneaking in.

We’ll wrap things up with a few FAQs, and send you back out into the great outdoors armed with the information you need to kick your unwanted insect guests to the curb.

Key Takeaways

  • Difficulty igniting your grill, uneven heating or flame distribution, hearing popping sounds from the burners, or smelling gas when the grill is on are all signs of spider webs in the venturi tubes, disrupting normal gas flow and combustion.

  • Routinely checking and cleaning your grill, particularly the burners and venturi tubes, is essential to prevent and remove spider webs and nests that cause blockages.

  • Protecting your grill with a cover when it’s not in use can deter spiders from making it their home, reducing the likelihood of blockages.

Here Are Some Signs That Your Grill May Have a Spider in It

Suspecting that your grill has become the new home for an eight-legged squatter? It’s not as uncommon as you might think, especially for grills that sit unused for a bit.

Spiders are drawn to the dark, secluded areas of your grill, such as the venturi tubes that supply gas to the burners, making it an ideal spot for them to set up camp.

Here are some signs that could indicate their presence:

Difficulty Igniting

If your grill isn’t lighting as easily as it used to, spider webs could be clogging the gas flow to the burners.

Visible Webs or Spiders

On closer inspection, you might actually see spider webs or the spiders themselves in the grill’s nooks, particularly around the burners or venturi tubes.

Popping Noises from the Burners

An unusual sound coming from the gas flow can indicate that webs are partially blocking gas movement. These sounds can occur when the gas flow is obstructed and then suddenly released as the grill is trying to light or stay lit, a common symptom of spider webs in the mix.

Uneven Heating or Flame Distribution

If you notice that your grill isn’t cooking as evenly as it used to, or if the flames seem to favor one side, it could be due to spider webs blocking the gas flow to certain areas.

Higher Than Normal Orange Flames

A clear, blue flame is what you’re aiming for. Orange flames, especially if they’re larger or more pronounced than usual, can signal incomplete combustion, often caused by obstructions like spider webs in the burners.

Popping Noises from the Burners

These sounds can occur when the gas flow is obstructed and then suddenly released as the grill is trying to light or stay lit, a common symptom of spider webs in the mix.

Grill Not Reaching Correct Temperature

If your grill struggles to get hot enough, even with all burners on high, it might be because spiders have restricted the flow of gas.

Smell of Gas Around Your Grill

Smelling gas when lighting your grill is normal, but if the odor persists while the grill is on and heated, it could mean that gas is leaking through blockages rather than burning off.

Control Knobs That Are Hot to the Touch

Normally, these should stay cool. If they’re hot, it might indicate that flames are being redirected unusually within the grill due to blockages, heating up areas that typically remain cool.

Flames Coming Out of the Front Control Knob Area

This is a clear sign that the intended gas paths are obstructed, causing gas to redirect and flames to exit through unintended openings.

Why Do Bugs and Spiders Love Your Grill as Much as You Do?

So why do creepy crawlers love hanging out in your grill just as much as you love hanging around it?

First off, the “rotten eggs” smell added to propane and natural gas to make it easier to detect a leak is pretty attractive to bugs and spiders.

Once the scent attracts them, they’ll often create a cozy nest inside the grill’s venturi tubes, safely away from predators and the elements.

They also love them for warmth and shelter. Grills, especially when not in use, provide a warm, sheltered environment that’s ideal for spiders and insects to hide, especially during cooler evenings or seasons. The secluded areas within a grill, like the venturi tubes and under the burners, offer perfect nesting spots.

Bits of food and grease that remain on the grill after cooking are a feast for various insects as well. These leftovers not only attract bugs but can also provide a food source for spiders that feed on these insects.

Another reason is that grills can retain moisture, particularly in the drip pans or when left uncovered in humid conditions. This moisture attracts insects looking for water, which then attracts spiders that prey on these insects.

Finally, spiders prefer dark, quiet areas where they can spin their webs undisturbed. The less frequently a grill is used, the more it becomes an ideal habitat for spiders seeking solitude.

How Do Spiders and Webs Cause Problems With Your Gas Grill?

We’ve covered many of the signs that your grill may have a spider in it above and we explained the problems that they can create.

The most troublesome reason is that spider webs and insect nests can partially or completely block your grill’s venturi tubes, where the air mixes with gas to create flames.

These blockages can cause gas to flow backward out of the tube and ignite around the gas valve. When this happens, you can end up with a “flashback” or a fire around the venturi tube, gas valve, and control knob panel.

How to Clean Venturi Tubes | When to Clean the Venturi Tubes

Despite your best efforts, a spider has gotten inside your grill and made a home for itself. Don’t worry — you can clean these out and reclaim your grill pretty quickly.

Carefully remove the grill grates and burner covers to access the burners and venturi tubes. This is where spiders are likely to build their webs.

Look for spider webs, eggs, or spiders themselves. Pay special attention to the venturi tubes—the hollow pipes that connect the burners to the control valves—as these are common hiding spots.

Inspect the burners for any obstructions caused by webs or debris. Use a small brush or compressed air to clear any blockages in the burner holes.

For accessible areas, a soft-bristled brush can be used to dislodge webs and debris. A vacuum with a hose attachment can then remove the loosened material from the grill.

How to Clean Venturi Tubes

To clean your venturi tubes, first shut your grill’s gas supply off at the source.

Next, remove the burner to expose the venturi tubes. How exactly you do this will depend on your model of grill — refer to your user’s manual for specific instructions.

Once the venturi tubes are exposed, look for signs of a web. Use a venturi brush or a pipe cleaner to gently clean inside the venturi tubes. These tools are flexible and designed to remove webs and debris without damaging the tubes.

Do not brush too quickly or push the webs to the back of the tube. Take your time to remove any debris from the tubes — even a tiny blockage can result in flashback fires or yellow flames.

Once you’re sure you removed all of the webs from the tubes, replace the burners and reconnect the grill to the gas supply. Turn on the grill and see if the flames or heat have changed.

When to Clean the Venturi Tubes

You should clean out your grill’s venturi tubes if your grill smells like gas, is producing a yellow flame, is not reaching the correct temperature, is heating unevenly, or has popping sounds coming from the burners.

Is There a Way to Prevent Spiders From Making a Home in Your Gas Grill?

Thankfully, many grill manufacturers are making efforts to keep these spider squatters out of your grill.

Some gas grills now come with small metal screens or “spider guards” on the air intakes to prevent spiders from getting inside.

These guards do need to be cleaned regularly, and even then, they aren’t perfect at preventing insects from getting inside. But they are a decent first line of defense to hopefully deter insect guests from even trying to crawl inside the tubes.

Another great way to help prevent spiders or bugs from getting into your grill is with a correctly-fitting grill cover. These covers can also do double duty and shield your grill from rust-causing elements like rain and snow.

And, of course, the best way to make sure a bit of spider web doesn’t ruin your day of grilling is by regularly inspecting and cleaning the burners and venturi tubes.

How to Handle Flashback Fires

If your grill is blocked by spider webs and a flashback fire occurs, you should immediately turn off the gas supply.

Turning the gas off should allow the fire to die down, but if it doesn’t, you’ll need to grab a fire extinguisher to kill the rest of the flames.

Once the fire is out and your grill has cooled, inspect your gas hoses, valves, and control knobs for damage. If the fire damaged any of these parts, they will need to be removed before you use the grill again.

Spiders in Your Gas Grill FAQs

Have some lingering questions about creepy crawlies getting into your grill? We’ve got answers to the most frequently asked questions.

Why Do Spiders Choose to Nest in Gas Grills?

Spiders are attracted to the dark, quiet, and protected areas inside gas grills for nesting, especially in the venturi tubes that offer an ideal environment for them to spin webs and lay eggs.

How Can I Tell if a Spider Has Made a Home in My Grill?

Signs include difficulty lighting the grill, uneven flame distribution, unusual noises from the burners, a smell of gas indicating incomplete combustion, or even flames emerging from non-standard areas like the control knobs.

How Can I Safely Remove Spiders and Their Webs From My Grill?

Turn off and disconnect the gas, carefully disassemble parts to access the affected areas, use a venturi brush or pipe cleaner for webs inside tubes, and clean all components before reassembling and testing the grill.

How Often Should I Check My Gas Grill for Spiders and Blockages?

It’s a good practice to inspect and clean your grill at the start of the grilling season and periodically throughout, especially if it’s used infrequently or stored in a place that’s likely to attract spiders.

Can Spider Webs in My Grill Cause Any Long-Term Damage?

Besides immediate safety concerns like gas buildup and uneven heating, long-term neglect of spider infestations can lead to corrosion and deterioration of grill components, reducing its lifespan and performance.

How Do I Keep Spiders Out of My Gas Grill?

To keep spiders out of your gas grill, regularly clean and inspect the grill, especially the burners and venturi tubes. Use a grill cover when not in use, and consider applying natural deterrents like peppermint oil around the grill area. Regular use can also discourage spiders from settling.

Spider in Your Gas Grill: Final Thoughts

While spiders nesting in your gas grill can seem like the stuff nightmares are made of, it’s a common problem you can solve with a little preparation and handiwork.

Remember, inspect and clean your burners and venturi tubes regularly, and always use a grill cover to protect your grill when you’re not using it.

While these steps should help prevent any unwanted visitors from moving into your grill, if they do sneak in, all you need is a Venturi brush and a careful cleaning session to evict them.

Armed with this knowledge, your grill should stay clean, spider-free, and ready for a great day of grilling!
