Full Application Instructions: Determine areas where rodents are most active, such as along walls, near burrows, or in drop ceilings. Remove alternative food sources before placement. Place 2 to 8 blocks for rats or nuisance animals and 1 to 2 blocks for mice in or around bait stations, snap traps, glue boards, or live catch traps. Blocks can be skewered on wire for hard to reach placements. Inspect bait regularly for feeding activity and replace as needed to maintain attractiveness. Once feeding is detected, transition to Selontra rodent bait for active control. Dispose of waste material and empty packaging according to local regulations.

Frequently Asked Questions:

Q: Does Prelontra rodent monitoring soft black contain an active ingredient?
A: No, there is no active ingredient in Prelontra. It is a nontoxic monitoring block that is not considered a rodenticide.

Q: Are there any safety concerns for Prelontra?
A: Prelontra is produced in a soft block formulation that is enrobed in a non-absorbent, odor-permeable polyolefin wrapper. The enhancement hole allows the block to be adequately secured in bait stations, minimizing the risk of bait displacement by the rodents around the site. Prelontra does not contain any of the 9 food allergens but is produced in a facility that processes the following food allergens: shellfish, wheat.

Q: What is the size of the Prelontra container?
A: Prelontra is sold in 8-pound resealable containers. Each container contains approximately 260 soft blocks that weigh 14 grams each.

Q: How much Prelontra should be used per bait station?
A: The directions-for-use of Prelontra state the following: Suggested placement is 2-8 blocks for rats/nuisance animals and 1-2 blocks for mice. The placement rate could require more or less blocks depending on the suspected level of infestation.

Q: When should Prelontra be replaced if activity has ceased or no activity is detected?
A: Prelontra is made of 100% food-grade ingredients. Like any bait, it performs best when it is fresh, so replacing it regularly ensures maximum attractiveness and effectiveness.

Q: How can I determine feeding with Prelontra?
A: Feeding can include light nibbling on the block to empty packaging. Since there is no active ingredient to stop target species from feeding, it is likely that bait stations can be cleaned out due to the palatable food source. The best management practice is to check stations regularly (each service visit).

Q: Can I remove the Prelontra from the wrapping?
A: Yes, the directions-for-use allow Prelontra to be removed from the packaging and placed on snap traps or in live animal traps. Empty packaging should be discarded in the trash.

Q: Can Prelontra be used around organic facilities, farms and storage areas?
A: Yes, the directions-for-use allow placement in/around agricultural buildings, including but not limited to swine, poultry, cattle, equine and dairy facilities; warehouses; food storage areas and food processing facilities. Pest Management Professionals should always check with their clients on any necessary organic certification programs to confirm Prelontra is acceptable for use in and/or around their facility operations.

Q: When is the right time to switch from Prelontra to Selontra® rodent bait?
A: Switch to Selontra as soon as any feeding activity on Prelontra is observed. Signs may range from light nibbling on blocks to complete consumption. Since Prelontra contains no active ingredient to deter feeding, it’s important to check bait stations frequently to minimize any delay in transitioning to Selontra.

Q: How can I tell the difference between Prelontra vs. Selontra?
A: Prelontra soft blocks are 14 grams, tan in color, and have no markings on the packaging. Selontra rodent bait is a 20-gram soft block, green in color, and the wrapping has printed language on them detailing the product name, precautionary statements, active ingredient, and EPA registration number.

Q: How should bait stations with Prelontra be labeled, and can Selontra labels be used on the same stations?
A: Regulations vary by state; most require some kind of labeling on (or in) the station to identify the contents. BASF offers bait station labels that list both products for easy identification (including a checkbox to select either Prelontra or Selontra – dependent on monitoring or active-control measures in place).
