How Contrac Blox Rodenticide Works

Contrac Blox rodenticide contains bromadiolone in small amounts. This toxin affects the rodents' nervous system and causes them to stop feeding. Gnawing on the toxic blocks causes the rats and mice to ingest the poison, which results in their deaths within four or five days. Because of the blocks' all-weather composition, they work well in outdoor areas regardless of rain or shine.

Where to Use Contrac Blox Rodenticide

Use Contrac All-Weather Blox Rodenticide in areas where rats and mice have been seen or may be hiding. The blocks are small enough to fit into gaps and burrows, including tight crevices around foundations. Each Contrac block has a center hole for securing the poison to a rod in a bait station. Use All-Weather Blox in and around homes, office buildings, airports, restaurants and other sites where mice and rats have infested living and working areas.

Quick Tip: Although there is an antidote for bromadiolone poisoning, it's wise to place Contrac Blox in a tamper-resistant baiting station to prevent children, pets and other animals from contacting the poison.
