MADISON, Wis. — Bell Laboratories’ bait Contrac is now available with Lumitrack, a special additive that makes rodent droppings glow bright green under UV light. When used as a perimeter bait, Contrac With Lumitrack helps PMPs determine if rodents are gaining access to a building’s interior and, if so, where those access points are. This provides valuable insight for establishing additional bait placements as well as where exclusionary methods need to be employed. Drop ceilings, sub-floors, wall voids and other dark, hard-to-access areas are also difficult to clearly document rodent activity. Using Contrac With Lumitrack, PMPs can identify and track rodent movement faster and more accurately, Bell Labs says. Contrac With Lumitrack uses the same Contrac formula, but in addition to Lumitrack, this formula also incorporates a new preservative system that inhibits mold growth even under harsh conditions. For a limited time, Bell is providing a free black light inside all 18-pound pails of Contrac With Lumitrack.
