Maybe you’ve tried several different traps but the moles are still digging. You’ve probably even tried all sorts of repellents, hoping they would keep the critters out. If you’re reading our The Giant Destroyer review, then you’re likely at your wit’s end when trying to deal with these intruders. Well, you’re in luck because your solution is here.

The Giant Destroyer by Atlas Chemical Corporation is a gasser that kills burrowing rodents such as moles, gophers, squirrels, and skunks. It works by releasing a thick cloud of toxic smoke into the critters’ tunnel and suffocating them. The name “The Giant Destroyer” is actually a brand, but we’ll focus on their gasser for this review.

The Giant Destroyer Overview

This product’s full name is actually quite a mouthful: The Giant Destroyer Super Gasser; but for simplicity’s sake, we’ll call it The Giant Destroyer. Not much is known about its manufacturer, Atlas Chemical Corporation, other than they claim to have introduced the brand in 1969. Regardless, the product is effective enough to still be in the market today.

The Giant Destroyer is basically a firework: you light the fuse and wait for it to ignite. But instead of producing a colorful display, it’s a smoke bomb that kills underground rodents. If you’re in the market for the best mole killers, then you might want to consider using this gasser.

Design and Construction

Each cartridge comes in a form of a cylinder, with one end designed to take a fuse. Inside is a combination of sodium nitrate, sulfur, charcoal, and other inactive ingredients. Sodium nitrate, which makes up nearly half of the formulation, aids in increasing the temperature within the cartridge to sustain the burn. The sulfur makes up the bulk of the toxic fumes, while the charcoal aids in producing the smoke.

Volume

The Giant Destroyer Review: Kill Moles and Gophers at Once (Winter 2023)
One package is enough for the yard.

Each pack of The Giant Destroyer comes with four cartridges, each containing 1.75 ounces of formula. There are 7 ounces worth of chemicals in total, and the packaging itself weighs around 8.4 ounces. Ideally, one cartridge’s worth of smoke should be enough; but for heavier infestations or larger creatures, you may have to use more than one.

How It Works

The Giant Destroyer is practically a “smoke bomb” – it produces a thick plume of smoke once its contents ignite. The spent fuse ignites the contents inside, creating a reaction and turning it into a smoke cloud. As long as the other tunnel entrances are properly sealed, all live critters within the vicinity will suffocate and die.

Required Tools

These gas cartridges technically don’t require any special tools to operate; most of the items you’ll be using are for preparation and safety. First and foremost, you’ll want some sort of mask to protect yourself from any accidental inhalation. You should also wear gloves in case of spillage.

For preparation, all you need is lighter to light the fuse. You may also need to gather other materials such as rocks, pebbles, or bricks; these will be used to seal other tunnel entrances.

How to Use It

The Giant Destroyer Review: Kill Moles and Gophers at Once (Winter 2023)
Apply it into the holes and tunnels to prevent appearing moles and gophers.

Using The Giant Destroyer is not complicated at all. Here’s how you use it:

  • Ensure all tunnel entrances are covered and blocked. You can use anything as long as it doesn’t let any smoke through.
  • Pick a tunnel opening for the gasser. Make sure it’s large enough to hold the cartridge in place yet clear enough to let the smoke travel.
  • Insert the fuse into the end of the cartridge. Leave about 2 inches of fuse hanging, then light the fuse away from your face and towards the hole.
  • Immediately place the lit cartridge into the hole with the fuse end going first. Then, cover that hole just enough to hold the gasser in place without smothering it.

Where and When to Use

One thing you need to remember is that The Giant Destroyer is for outdoor use only. If rodents such as squirrels happen to burrow close to your house, you might want to look for the best squirrel traps instead. Traps can get rid of rodents without endangering your health.

And because each cartridge works via a slow, contained burn, double-check that the ground isn’t too dry or too wet. If it’s dry, you run the risk of dried leaves and grass catching fire from the fuse; if it’s wet, the fuse will simply get extinguished. Check the weekly weather forecast to get an idea of when to use this product.

Special Things to Consider

Even though the EPA considers the exposure from this product as “minimal,” take proper precautions just in case. Always wear a mask and a pair of gloves, and make sure the area where you insert the cartridge isn’t surrounded by flammable materials. You don’t want The Giant Destroyer to be the cause of the fire on your property.

Depending on where you live, The Giant Destroyer may also be illegal to use. If you live in California, you cannot use this item to eliminate woodchucks. Similarly, those who live in North Carolina can only use this product on Norway Rats and nothing else.

Safety Information

The Giant Destroyer Review: Kill Moles and Gophers at Once (Winter 2023)
Before using it, read the instruction carefully and wear protective gloves.

In case of accidental inhalation, immediately move to an area with fresh air. The product’s safety data sheet lists its inhalation effect as mildly irritating, so you may encounter some coughing for a short period of time. The coughing should subside in a few minutes; if it doesn’t, or if it gets worse, call a doctor immediately.

For accidental skin contact, wash the affected area with lots of water immediately. The safety data sheet doesn’t list any known effects on the skin, so seek medical help right away if you develop a reaction.

And if the treatment site catches fire, never put water directly on the blaze. Instead, use foam or carbon dioxide – these should be readily available as a household fire extinguisher. If the fire spreads, call the fire department right away.

Maintenance

The Giant Destroyer, if used properly, should not require any maintenance. Make sure you wait a few days before checking the treatment site in case there’s still any lingering smoke within the tunnel. If you suspect continued rodent activity, use another cartridge. Once successful, consider buying the best gopher repellents to make sure they never come back.

Efficiency and Warranty

If your lawn is heavily infested, or if you have multiple runways, you may have to use more than one cartridge at a time. As long as you follow the usage instructions, your underground rodents should be dead in no time.

However, if your cartridge is defective, call Atlas Chemical immediately. There is no warranty information available on the packaging or online, but the company has previously sent out replacement cartridges to affected customers.

Price

The Giant Destroyer is available in various brick-and-mortar stores for less than $10, with the cheapest retailer selling it for less than $5. If you can’t find one in your area, or if you don’t live near a store that sells them, they are available online for about $15.

What’s Included in the Set

A set comes with four cartridges and some fuse. It’s minimally packaged: the cartridges are held together by a plastic case and sealed with a cardboard backing label.

Key Features:

PROS CONS
  • Relatively inexpensive compared to other pest traps and poison.
  • The formulation has been proven to work since 1969.
  • Requires no other special tools to use.
  • Needs quite a bit of prep work to ensure the smoke does not escape.
  • One cartridge may not be enough if the tunnel system is large or if the creatures are resistant.
  • Some states restrict the use of this product to specific pests only.

Conclusion

Our The Giant Destroyer review should prove to you that you don’t need to spend hundreds of dollars to solve your rodent problems. It’s been in the market since 1969 so you know it works. If you’ve been looking for a way to get rid of your infestation once and for all, then you may have just found it here.
