Fastrac Blox Poison Bait
04/10/26
Fastrac Blox are manufactured by Bell Laboratories and are weather-proof and moisture-proof rodenticide blocks formulated with bromethalin to kill rats and mice. The bait blocks are effective for use indoors and outdoors to control for Norway rats, roof rats and house mice. Fastrac Blox are strong enough to provide a lethal dose in one feeding. Each Fastrac block has multiple edges to entice rodents to chew on the bait.
Fastrac Blox is a great product to have when combating severe infestations, as the active ingredient, bromethalin provides faster results with less bait than anticoagulant baits.
Tools Needed
To safely apply Fastrac Blox around outdoor areas, tamper-proof bait stations are required.
How to Use
- Step 1: Locate areas where rats/mice travel by searching for droppings or chew marks on baseboards and walls and remove all secondary food sources to prevent targeted rodents from refusing Fastrac Blox.
- Step 2: For rats, place 2 to 12 Fastrac Blox bait blocks per placement at intervals of 15 to 30 feet apart. For Mile and Meadow Voles, use 1 block per placement 8 to 12 feet apart in infested area. For areas with high mouse activity, use 2 blocks per placement.
- Step 3: Place Fastrac Blox in tamper-proof bait stations. We recommend sitting out empty bait stations for a few days so targeted pests will become familiar with them. Place the filled bait stations along exterior walls or fence lines with the holes closest to the structure.
- Step 4: After one or two days, inspect the stations and replenish the bait until rodent activity has stopped. Keep the areas clean, but do not wash the station until the eradication process is complete. Using gloves, collect and properly dispose of all dead, exposed animals and leftover bait.
Where to Use
Fastrac Blox can be placed in infested areas outdoors with a bait station or indoors. The bait stations filled with the bait blocks can be placed along walls around the outside perimeter of grocery stores, barnyards, homes, hotels, restaurants, and along fence lines. Fastrac Blox being used indoors can be placed within walls, under sinks, in attics, and other areas where pets or children cannot access the bait.
When to Use
Fastrac Blox are ideal to use when rat or mouse activity is suspected. It is recommended that areas that have continuous situations that attract rodents, such as barnyards, grocery stores or restaurants should also have continuous control and keep bait stations filled with Fastrac Blox.
Safety Information
Fastrac Blox are safe to use around children, pets, and livestock when used according to the product label. Do not place Fastrac Blox where children, pets, livestock, and innocent animals can gain access. Always wear the proper personal protective equipment (PPE) when handling Fastrac Blox or bait stations.
Special Considerations
