Choosing the right bait for the job

Feb 2, 2022

The Level of Rodent Activity Determines the Appropriate Bait for the Job. Proper Selection and Application of These Baits Will Determine the Success of Any Rodent Control Program.

We Have Put Together Important Information about What Rodent Bait Options Are Available, to Help You Make an Informed Decision When Choosing the Right Bait for the Job.

Rodenticide Types

Extruded Blox

  • The most popular choice of bait form.
  • It is highly palatable and weatherable.
  • It can be used indoors and outdoors (refer to the product label for product placement).
  • It features multiple gnawing edges.
  • Has a hole down the center for securing on rods in tamper-resistant bait station.


  • Can be used indoor and outdoor (around buildings).
  • It is hard and compact shape satisfies a desire to gnaw.

Regardless of which bait offered by PES Africa is chosen, the use of our Guardian Bait tamper-resistant bait station is highly recommended.

Types of Active Ingredients


Anticoagulants can be put into two different categories: 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.

With anticoagulants death is delayed as it disrupts the normal blood clotting and causes internal bleeding. Even though 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 veterinary professionals. We always recommend the use of resistant-proof bait stations when using rodent baits.

Second Generation Anticoagulants

These types of rodent baits are our first recommendation, 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 SA are bromadiolone, brodifacoum, and bromethalin. 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

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.
Antidotes: Vitamin K1 treatments


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. It is important to use tamper-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.

Antidotes: There is no direct antidote, however there are treatment programs for sub-lethal ingestions.
