Active ingredient
Bromethalin
Neurotoxicant rodenticide
A rodenticide, sold for moles in a bait shaped and scented as an artificial earthworm rather than as grain.
What it does
Works on the animal it is formulated for. The worm shape matters because moles are insectivores — a grain bait is the wrong food for them, which is why grain baits sold for moles routinely fail.
What it does not do
It does nothing about the cause. Moles are in the lawn for the invertebrates in it, and grub control is not mole control — the two are separate problems with separate answers.
The label constraint people miss
This is a vertebrate poison with secondary-exposure risk to pets and non-target wildlife. Placement is in an active tunnel rather than broadcast, and one state in our data prohibits the trapping alternative outright, which changes the options rather than the caution.
Products we review that contain it
Every product below is here because we opened its label — on EPA's own database or the registrant's — and read Bromethalin in the ingredient statement. Registration numbers are on each product's page.
Bromethalin Mole Bait (artificial earthworm form)
Tomcat Mole Killer, 12 Worm Baits
★★★★☆ (4.2/5)
The only bait category on this shelf built for what a mole actually eats — and the reason it works is exactly why it deserves care around a dog.
Best for: Killing moles in confirmed active tunnels where a trap is impractical
$17–$22

Zinc Phosphide Grain Bait
Victor Outdoor Mole & Gopher Poison Peanuts (4-pack)
★★☆☆☆ (1.8/5)
It says mole on the front. Purdue Extension says a mole cannot be baited with a grain product, because a mole does not eat grain.
Best for: Pocket gophers — a rodent that actually eats grain bait
$18–$24

Refillable Rodent Bait Station
Tomcat Mouse Killer Refillable Station with 16 Bait Blocks
★★★★☆ (4.1/5)
Listed on this shelf for one reason: voles are rodents and moles are not, and the station's child- and dog-resistant design is the part worth paying for.
Best for: Mice around a house or outbuilding, in a tamper-resistant station
$9–$14

Bromethalin Mole Bait (artificial earthworm form)
Bell Laboratories Talpirid Mole Bait Worms (20 count)
★★★★☆ (4/5)
The product the trade treats as the category standard — and, by its own EPA registration number, the same registered bait sold for a third less under a consumer brand.
Best for: Larger tunnel networks where 20 baits in one box is worth the premium
$48–$58

Bromethalin Mole Bait (artificial worm form) with marker flags
Victor Poison Moleworms with Tunnel Locator Flags (10-pack)
★★★★☆ (4.3/5)
The only bait in this group that ships the thing most people actually get wrong: five flags for marking which tunnels you have confirmed are active.
Best for: A first mole bait purchase — the flags make correct placement realistic
$16–$21

Guides that use Bromethalin
Buy for the active, then read the label anyway. Two products with the same active are not interchangeable — concentration, labelled sites and species tolerances all vary, and a three-part registration number means a narrowed label. How to read one in two minutes. Where our page and your container disagree, the container is the legal authority.
