Do gopher smoke bombs actually work?
Let's get the honest part out of the way, because most pest articles won't say it: as a way to kill gophers, smoke is inconsistent at best. That goes for the sulfur gas cartridges sold at garden stores, and it absolutely goes for our products. We sell visual-effect smoke grenades — photography and event smoke — not pesticides, and nothing we make is designed to kill anything.
So why are you reading a gopher article on a smoke bomb site? Because there's one job in gopher control where smoke is legitimately the best tool available: finding out where the tunnels actually go. A gopher's network can run a long way under a lawn with only a handful of visible mounds. Dense colored smoke pushed into one entrance will pour out of every connected opening, and suddenly the invisible problem is a visible one.
That's the deal this guide offers. We'll show you the mapping method that works, tell you plainly what doesn't, and point you to trapping — the fix that actually clears a yard.
Why smoke fails as a kill method
Gophers are burrow-defense specialists. When they detect smoke, gas, water, or even a change in airflow, their first move is to bulldoze a soil plug into the tunnel — and they can seal off a section in well under a minute. The gopher ends up safe behind a dirt wall while the smoke or gas dissipates harmlessly in the sealed-off section.
This is why the dedicated fumigation cartridges from the hardware store get such mixed reviews. They can work when the burrow is small, fresh, and the animal is close to the charge. In an established network with deep chambers and multiple laterals, the gopher usually just walls itself off and digs a new exit a day later. You've spent money, made smoke, and moved the problem three feet.
Our smoke is even less lethal than those cartridges, by design. Enola Gaye smoke is non-toxic and cool-burning — it produces dense colored smoke for visual effects, not toxic gas. We will never claim our products kill gophers, because they don't. What they do, better than anything else you can buy for the money, is make air movement visible.
What smoke is genuinely good for: mapping the tunnel network
Here's the insight that makes smoke worth using: a gopher network is a ventilation system. Every entrance, exit hole, and feeder mound is connected by tunnels that air flows through. Push a high volume of visible smoke into one opening and it will escape from every other opening it can reach — including holes hidden in tall grass, under shrubs, or in a neighbor's flower bed that you had no idea existed.
Gray fumigant smoke is hard to spot against soil and sky. A saturated color — pink, orange, blue — reads instantly against green grass, even from across the yard. That's why a photography smoke grenade is, somewhat absurdly, an excellent tunnel-mapping tool. Our WP40-D wire pull ($12.50) puts out roughly 60 seconds of dense colored smoke — enough volume and enough time to pressurize a typical residential tunnel run and light up every exit.
Will the gopher plug tunnels while you do this? Probably, eventually. But plugging takes it time, and the smoke front moves through the network far faster than one animal can seal every branch. You're not trying to gas the gopher — you're taking a 60-second snapshot of the architecture. Even a partial map beats guessing.
How to smoke-map gopher tunnels, step by step
You'll need one WP40-D (or two for a big yard), a trowel or hori-hori knife, gloves, a helper, and a handful of marker flags or golf tees. Pick a calm, dry-ish morning — wind shreds the plumes before you can spot them, and fresh mounds are easiest to find early in the day.
- Find the freshest mound. Fresh gopher mounds are fan- or crescent-shaped with dark, moist, crumbly soil and a visible dirt plug off to one side. Old, crusted mounds sit over tunnels the gopher may have abandoned — start with the newest dirt.
- Open the lateral tunnel. The plugged entrance sits on the flat side of the fan, usually 6–12 inches from the mound's center. Probe with the trowel until the ground gives way, then dig down until you expose a clean, open tunnel about the diameter of your forearm. You want a real opening into the run, not a hole in loose mound soil.
- Position your helper. Send them to the far side of the affected area with the flags. Their only job for the next two minutes is to scan the ground and flag every spot where smoke appears.
- Ignite and feed the smoke in. Stand upwind, pull the wire ring, and point the vent directly into the tunnel opening — get the canister mouth as far into the hole as you comfortably can, or seat it just inside and pack loose soil around the sides so the smoke has nowhere to go but down the run. Never seal it airtight; let it breathe and push.
- Flag every plume. For the next 60 seconds, colored smoke will wisp or pour from every connected opening — sometimes 10, 20, even 40 feet from where you're standing. Flag each one, including faint seeps from soil cracks. Faint seeps often mark shallow feeder runs, which are prime trap locations.
- Sketch the network. Once the unit burns out, walk the flags and rough out the layout on paper or your phone. Connect the dots between the entry point and each exit — the lines between them approximate the main runs.
- Repeat from a second mound if needed. If a distant cluster of mounds produced no smoke, it's likely a separate tunnel system (or a plugged branch). Open a fresh mound there and run a second unit.
Total time: about 20 minutes for a job that would otherwise take days of probing blind. If a unit fails to ignite, check our smoke bomb troubleshooting guide — and remember every unit is covered by our 100% Product Guarantee (1.5× store credit or a refund if one fails).
After the map: set traps on the runs you found
Mapping is step one. Removal is step two, and for DIY the answer is trapping — it's the method university extension offices consistently rank as the most reliable, and it's cheap. Box traps and pincer-style traps (Macabee, Victor, Gophinator types) all work when they're placed in an active run, which is exactly the information your smoke map just handed you.
- Trap the main runs, not the mounds. The straight lines between your flagged exits are the highways. Dig into a run, set paired traps facing opposite directions, and cover the hole loosely.
- Check traps daily and move them after 48 quiet hours. A trap that hasn't fired in two days is in the wrong tunnel — your map gives you the next spot.
- Call a pro for big infestations. If you're flagging exits across a half-acre or the mounds keep multiplying, a licensed wildlife or pest operator with trapping experience will clear it faster than weekend warfare. Hand them your smoke map; they'll appreciate it.

What NOT to do
A few methods circulate endlessly online that range from useless to genuinely dangerous. Skip all of these:
- Gasoline down the hole. Never. You're pouring an explosive, groundwater-contaminating liquid into a ventilation network under your own lawn. It rarely reaches the gopher and the fire and vapor risk is real.
- Car exhaust piped into the burrow. A popular internet trick, and a bad one — you're running a hot engine unattended with an improvised hose rig, generating carbon monoxide near where you're standing and working. The gopher usually plugs the tunnel anyway.
- Chewing gum, glass shards, ultrasonic spikes. No credible evidence any of these work. Save the money for traps.
- Flooding, by itself. Water can push a gopher to the surface occasionally, but established networks drain and the animal rides it out in a high chamber. At best it's a soggy version of the smoke problem.
Safety basics before you light anything
Our smoke is non-toxic and cool-burning, but the ignition end of any smoke grenade is hot, and you're using it at ground level in vegetation. Take five minutes on this list:
- Check conditions. If your area is under a burn ban or red-flag warning, don't do this — wait. Dry, brown grass around the mound is a no-go; clear a bare-soil ring around your entry hole before igniting.
- Stay upwind and outdoors. Non-toxic doesn't mean breathe it on purpose. Position yourself so drifting smoke moves away from you, and never use smoke products indoors or in enclosed spaces.
- Wear gloves. For the digging as much as the smoke — gopher tunnels can host fleas, and soil-borne bacteria and hot canister bodies both argue for leather work gloves.
- Keep water or a shovel handy. Standard practice for any ground-level ignition. You'll almost certainly never need it; have it anyway.
- Let spent units cool before you pick them up — a few minutes on bare soil does it.
One shipping note if you're planning ahead: smoke products ship ground-only within the contiguous US (no Massachusetts, no AK/HI/PR), so order a few days before your gopher campaign, not the morning of.
Frequently Asked Questions
Do gopher smoke bombs work?
As a kill method, inconsistently — gophers plug tunnels fast when they detect smoke, so garden-store gas cartridges are hit-or-miss and visual smoke like ours doesn't kill them at all. Where smoke works reliably is as a mapping tool: it reveals every connected exit hole in about a minute, which makes trapping far more effective.
How do you smoke out gophers?
Find the freshest mound, dig open the lateral tunnel beside it, ignite a wire-pull smoke grenade, and feed the smoke directly into the opening. Have a helper flag every spot where smoke escapes over the next 60 seconds. You're not smoking the gopher out of the ground — you're mapping the tunnel network so you can trap it.
What is the best gopher smoke bomb?
For killing, none are reliable — that's trapping's job. For mapping tunnels, you want dense, brightly colored smoke with about a minute of output. Our WP40-D wire pull ($12.50, ~60 seconds of dense colored smoke) is what we'd use: the color makes even faint plumes visible against grass from across the yard.
Will Shutter Bombs smoke grenades kill gophers?
No, and we won't pretend otherwise. Our products are non-toxic, cool-burning visual-effect smoke made by Enola Gaye — designed for photography and events, not pest control. They're excellent for locating tunnel exits; for removal, set traps on the runs you map or hire a pro.
Is a gopher smoker or gas cartridge worth buying?
Sometimes, in small fresh burrows — but reviews are mixed for a reason. Gophers seal off tunnel sections quickly, so cartridges often fumigate an empty, walled-off run. If you go that route, at least smoke-map the network first so you know where the active tunnels are.
What actually gets rid of gophers for good?
Trapping is the most reliable DIY method: set paired traps in the active main runs, check daily, and relocate any trap that sits quiet for 48 hours. For large or recurring infestations, a licensed pest professional is worth the money. Smoke mapping makes both approaches faster by showing you exactly where the runs are.
Ready to map your gopher tunnels?
One or two WP40-D units, a trowel, and a helper with flags will show you a gopher network that's been invisible for months. Map it this weekend, set your traps on the runs, and stop guessing.
