Watching your lawn transform into a moonscape of fresh dirt mounds is frustrating, especially when the culprit, a single pocket gopher, can dig hundreds of feet of tunnels in a single night. The right bait is the only direct way to reclaim your yard without trapping every single rodent.

I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years digging into the chemistry and field performance of rodenticides, comparing active ingredients, application methods, and real owner feedback to separate the formulas that actually stop gophers from the ones that just feed them.

I’ve analyzed hundreds of product datasheets and thousands of owner reports to bring you the most reliable, category-specific guide to selecting a bait for gophers that delivers results without unnecessary risk to your pets or local wildlife.

How To Choose The Best Bait For Gophers

Pocket gophers are strict herbivores that rarely surface, so bait must be placed directly into their tunnel systems to be effective. Choosing the right bait comes down to understanding the active ingredient, the bait form, and application safety.

Active Ingredient: Zinc Phosphide vs. Anticoagulants

Zinc phosphide is a fast-acting, non-anticoagulant poison that reacts with stomach acid to produce toxic phosphine gas, often killing a gopher within hours of ingestion. Anticoagulants like warfarin or chlorophacinone cause internal bleeding over several days, requiring multiple feedings. For a single-treatment knockdown, zinc phosphide is generally more reliable.

Bait Form: Granules, Pellets, or Gassers

Granules and pellets are placed directly into active tunnels where gophers encounter them while digging or foraging. Gassers use a chemical reaction to fill the tunnel with carbon monoxide and smoke, suffocating the pest without ingestion. Granules offer better residual activity, while gassers provide immediate results without the risk of secondary poisoning.

Application Safety and EPA Status

All baits listed here carry EPA registration, meaning they have been evaluated for environmental and human safety when used according to the label. Wear gloves during application to avoid leaving human scent on the bait, and never place bait on the surface to prevent accidental ingestion by pets or non-target wildlife.

1. Motomco 32553 Gopher Killer

Zinc PhosphideNon-Anticoagulant

The Motomco 32553 is a zinc phosphide-based bait formulated specifically for pocket gophers and widely used by agricultural professionals. It kills quickly after a single feeding by producing phosphine gas in the stomach, which is why many owners report seeing a reduction in mounds within 48 hours. The bait also works on moles and voles when placed correctly.

Application requires a probe to locate active tunnels, then inserting roughly a tablespoon of bait every several feet. Owners using this method on acreage reported dropping 6-8 mounds down to just 2 in three days, making it one of the fastest options available. The EPA registration confirms it meets federal standards for underground use.

Some users noted that gophers returned after a few weeks, requiring rotation with other baits to maintain control. A small number of owners found the bait completely ignored, which may indicate incorrect tunnel identification or an established colony that has already consumed other food sources.

What works

  • Fast-acting non-anticoagulant formula kills after single feeding
  • Effective across gopher, mole, and vole populations

What doesn’t

  • Some gophers may ignore bait if fresh plant food is abundant
  • Requires careful glove use and tunnel location for best results
Premium Pick

2. Bonide Gophertox Gopher Killer

Zinc Granules1 lb Ready-to-Use

Bonide Gophertox is a targeted zinc-based granular bait designed exclusively for pocket gophers in residential lawns and flower beds. The label specifies that one teaspoon treats a single active burrow, making it economical for small to medium properties. The fast-acting pellets are placed directly into tunnels, where gophers encounter them while digging.

Owners reported excellent results with a single application, noting that the gopher activity ceased completely after using the product correctly. The formulation also helps protect flower bulbs when placed around them at fall planting, which adds versatility for gardeners who also maintain ornamental beds. No mixing is required, so you can open the jug and apply immediately.

A few reviewers found the product ineffective against persistent infestations, with one owner reporting that the gophers appeared to ignore the bait entirely. The inconsistency may be due to the gopher’s preference for fresh vegetation over grain-based pellets, or the need to rotate active ingredients with other baits.

What works

  • Very economical at 1 teaspoon per active burrow
  • Ready-to-use granules require no mixing

What doesn’t

  • May be ignored if gophers prefer fresh plants over grain
  • Mixed results reported on heavy, established infestations

3. Revenge Moletox Mole & Gopher Killer

Zinc Granules16 oz

Revenge Moletox from Bonide is a dual-purpose granular bait formulated for both moles and pocket gophers, making it a cost-effective option if you’re dealing with both pests. The fast-acting zinc formula treats active burrows with just a teaspoon per tunnel, and it can also be used to protect flower bulbs during fall planting. The ready-to-use granules eliminate the need for mixing or measuring.

Several homeowners on larger properties reported that this product worked well against gophers and even skunks that were digging in the same areas. The low price point per pound makes it an attractive choice for first-time buyers who want to test a bait without a major investment. The bait is intended only for manual underground application, so surface scattering is not recommended.

Some users experienced poor results, with the bait seemingly ignored by the gophers. There were also reports of the packaging arriving opened or with damp granules, which suggests quality control issues during shipping. The product has a strong odor that may deter some animals, and its effectiveness appears to depend heavily on proper tunnel identification.

What works

  • Works on both moles and pocket gophers in one treatment
  • Economical price per pound for testing

What doesn’t

  • Packaging may arrive opened or granules may be damp
  • Effectiveness drops sharply with incorrect tunnel location
Heavy Duty

4. Quick Strike Mole & Gopher Gasser, 4-Pk

Smoke GasserCarbon Monoxide

The Quick Strike Gopher Gasser uses a different mechanism than bait granules: it produces smoke and carbon monoxide that fills the tunnel system, suffocating the gopher without requiring ingestion. Each cartridge is ignited like a road flare, placed into an open tunnel, and then the hole is covered to trap the gas. The manufacturer claims each cartridge provides eight hours of coverage in the tunnel network.

This method avoids secondary poisoning entirely, which makes it attractive for properties with free-roaming pets or chickens. Some owners reported success against underground yellow jacket nests as well, adding versatility beyond rodent control. The gasser is made in the USA and requires no baiting or tracking of feeding patterns.

Several users found the gasser ineffective, with moles and gophers returning within days. A notable complaint involved faulty ignition charges or missing strike pads, preventing the cartridge from lighting. The smoke may not reach every branch of a complex tunnel system, leaving some gophers alive after treatment.

What works

  • No ingestion required; suffocates pests via carbon monoxide
  • Safe for pets if used correctly with no surface poison

What doesn’t

  • Ignition mechanism may fail on some cartridges
  • Smoke may not reach all tunnel branches

5. Motomco Mole Killer Ready to Use Bonus Box

Worm BaitIndividually Packaged

The Motomco Mole Killer Bonus Box uses a unique approach: it contains toxic worm-shaped baits that mimic the natural food source of moles. The worms are individually packaged, which helps preserve their scent and texture. While marketed primarily for moles, owners have found it effective against voles as well, and some have used it for pocket gophers with success.

The key to effectiveness is placing the worms in the main runway tunnel, not in the feeder mounds. Owners recommend locating the tunnel, cutting a small hole, dropping in a worm, and covering the opening. Many repeat buyers consider it the best product they have used, with one owner stating it works “better than any product to kill voles and moles.”

The biggest drawback is the limited quantity per box and the high cost per worm, which can approach a premium per application for larger properties. Some users saw continued tunneling after use, indicating the worms may not be attractive to every pest species. The product is also less suitable for gophers than for moles, as gophers do not naturally hunt for worms.

What works

  • Individually packaged worms remain fresh and scented
  • Works well against voles and moles when placed in main tunnel

What doesn’t

  • High cost per worm makes large area treatment expensive
  • Less attractive to gophers than grain-based baits

Hardware & Specs Guide

Zinc Phosphide Concentration

The active ingredient percentage determines how much is needed per tunnel. Most baits contain around 2 percent zinc phosphide, which is the standard for residential use. Higher concentrations work faster but require stricter handling to avoid accidental poisoning.

Bait Form and Application

Granules and pellets must be placed inside active tunnels using a probe or spoon, while gassers require ignition and rapid hole sealing. Worm baits are placed directly into the tunnel and mimic natural prey, which works best for insectivores like moles rather than herbivorous gophers.

FAQ

How do I find the active gopher tunnel for bait placement?
Probe the ground between fresh mounds using a long screwdriver or rod. When you feel the soil drop into a void, you have located the main runway tunnel. Open a small hole, drop in the bait, and cover it with soil or sod to block light, which encourages the gopher to come and seal the breach.
Will gopher bait kill my dog or cat if they dig it up?
Yes, if a pet ingests a large amount of zinc phosphide bait, it can be toxic. Always bury bait at least 6 inches deep in the tunnel and cover the hole completely. Never scatter bait on the surface. If you have free-roaming pets, consider a gopher gasser instead, which leaves no poison residue in the soil.

Final Thoughts: The Verdict

For most gardeners, the bait for gophers winner is the Motomco 32553 Gopher Killer because its fast-acting zinc phosphide formula kills after a single feeding and is backed by professional agricultural use. If you want to avoid ingestion-based poisons, grab the Quick Strike Gopher Gasser for its smoke-based suffocation method. And for a budget-friendly way to test a dual-purpose bait for moles and gophers, nothing beats the Revenge Moletox Granules.
