Contrac All-Weather Blox 18 LB Pail – Bulk Rat & Mouse Bait for NYC Buildings

The workhorse bulk rodenticide of the NYC pest control industry. Contrac All-Weather Blox is a multi-edged block bait formulated to withstand NYC's harsh conditions — from damp building basements and utility tunnels to outdoor perimeter placements. Its 18 lb pail is the standard supply format for building supers and property managers running building-wide rodent programs.

Contrac's bromadiolone formula (single-feeding anticoagulant) is effective against both rats and mice that may have developed resistance to first-generation anticoagulants. The all-weather block resists moisture and mold — critical for NYC basement and exterior placements.
