Rodent Bait Forms and Use Tips

• Types of Baits: Available as single-feed (faster-acting) or multiple-feed (requires repeated consumption).
• Blox and Block Forms: Weatherproof and suitable for outdoor use in bait stations.
• Pellets and Meal Forms: Non-weatherproof—best used indoors or in dry, protected areas.
• Soft Bait Forms: Non-weatherproof, but extremely palatable—even in the presence of other food sources.
• Sewer and Burrow Baiting: Follow product label restrictions or call us for guidance on safe application.

Anticoagulant Rodenticides

Anticoagulants are rodent baits that work by disrupting blood clotting, causing delayed internal bleeding without pain or bait shyness. They are classified into two types:

• First-Generation: Multiple-feed baits requiring consistent consumption over time. Ideal for long-term maintenance and carry a lower risk to non-target animals.
• Second-Generation: Single-feed baits are effective after one dose. Highly palatable and fast-acting—best for resistant rodents and heavy infestations.

Anticoagulants

Anticoagulants are divided into first-generation and second-generation anticoagulant baits. The first-generation anticoagulants require multiple feedings (multiple-dose) for a lethal dosage, and the second-generation anticoagulants (single-dose) require only one feeding for a lethal dosage. Death is delayed with anticoagulants as it disrupts the normal blood clotting and causes internal bleeding. Even though the death is delayed, it is not painful. The rodents do not associate the anticoagulant with death., so they do not develop bait shyness. The treatment protocol for accidental poisoning is Vitamin K, which is readily available by vets. We always recommend the use of resistant-proof bait stations when using rodent baits. Currently, second-generation anticoagulant baits can only be sold in 16 lbs or more per EPA.

• Second Generation Anticoagulants-These types of rodent baits are our first recommendations, due to their great bait acceptance. They kill rats and mice that are resistant to first-generation rodent baits. Common active ingredients available in the USA are bromadiolone, brodifacoum, and difethialone. Rodent baits with these ingredients kill with very little bait consumed. These baits are beneficial for heavy infestations and where there is high food competition. These baits also are used where there is persistent rodent infestation, and may also be used for occasional invaders.
  • Antidotes: Vitamin K1 treatments

  • Brodifacoum-Final Soft Bait, Final Blox, Final Pellets, and Weatherblox XT
• First Generation Anticoagulants-These are multiple-dose rodent baits. Rodents need several feedings (over 3-10 days and more for mice control) to be effective. These baits must be available continuously until all the rodents stop feeding (this may take 2-3 weeks). These baits have a lower risk for non-targeted animals since multiple feedings are required. These baits are best for maintenance situations. These baits may be sold in any weight containers.

Non-Anticoagulants

Manner of death varies with non-anticoagulants. Some act as a nerve poison and other types depletes the calcium from the bones, resulting in death. The ones that we carry are single-dose, with just one dose for a lethal dosage. It is important to use resistant bait stations because there is no effective antidote if accidental ingestion occurs. You have less of a chance of secondary poisoning with non-anticoagulants as opposed to second-generation anticoagulants.
