Formus Blox

Free Shipping on All Orders

FORMUS contains the powerful single-feed, second-generation anticoagulant, Brodifacoum, in an economical 15g BLOX. Specifically developed to appeal to mice, every ingredient in FORMUS was chosen with a focus on mice - with the ultimate aim of controlling the most difficult mouse infestations.

FORMUS is formulated with its active ingredient at 0.0025 percent, half the concentration of conventional Brodifacoum baits. Yet this new bait from Bell is strong enough to control both rats and mice with lower risk to non-target animals and less risk of secondary toxicity.

Half the size of Bell's extruded BLOX, the 15g FORMUS BLOX lets PMPs put out smaller placements of bait in more locations which can lead to better mouse control.

FORMUS meets the Environmental Protection Agency's (EPA) single-feed guidelines that require a rodenticide to kill after only 24 hours of exposure to the bait. Its advanced preservation system also reduces the risk of mold and mildew and it is melt resistant to 170 degrees F, higher than most baits on the market.

FORMUS readily fits in Bell's PROTECTA RTU and Keyless Mouse Bait Station. The center hole in the BLOX also lets PMPs secure it on bait securing rods in Bell's larger PROTECTA rat and mouse tamper-resistant bait stations.

Target Pests

House Mice Norway Rats and Roof Rats


Determine areas where rats or mice will most likely find and consume the bait. Generally, these areas are along walls, by gnawed openings, in corners and concealed places, between floors and walls, or in locations where rats or mice or their signs have been seen. Protect bait from rain and snow. Remove as much alternative food as possible.

RATS: Place 7-30 blocks at intervals of approximately 15-30 feet in appropriate locations in infested areas. Maintain an uninterrupted supply of fresh bait for at least 10 days or until there no longer are signs of rats feeding on bait.

For use in sewers, thread wire through blocks and securely attach to a stationary structure such as the bottom step of a manhole ladder or a sewer grate. Allow just enough wire for the blocks to rest on manhole benching. If benching is not present, suspend blocks a few inches above the high water mark or secure blocks on a board supported by opposing steps of the ladder. Securing blocks in this manner may inhibit removal by rats or water. Use at least 20 blocks per manhole. Maintain an uninterrupted supply of fresh bait for at least 10 days or until signs of rat activity cease.

MICE: Place 1 block per placement. Space placements at 8 to 12 foot intervals in infested areas. Two blocks may be needed at points of very high mouse activity. Maintain an uninterrupted supply of fresh bait for at least 15 days or until signs of mouse activity cease.

FOLLOW-UP: Replace contaminated or spoiled bait immediately. Wearing gloves, collect and dispose of all dead, exposed animals and leftover bait. To prevent reinfestation, limit sources of rodent food, water, and harborage as much as possible. If reinfestation does occur, repeat treatment. Where a continuous source of infestation is present, establish permanent bait stations and replenish as needed.
