Sale price$101.80


Contrac Blox is a rodenticide used for killing and controlling rat and mice infestations in residential, commercial and industrial areas. It contains a very poisonous ingredient that starts to work at the moment of ingestion and kills the rodent within 48 hours. The bait block has a protective covering to prevent degradation in the rain and a tasty formula for encouraging consistent feeding.

How Contrac Blox Works

This rodenticide bait has a weather-resistant coating, so it can be used outdoors and remain effective in the elements. Each all-weather Blox contains the active ingredient bromadiolone, an anticoagulant. After ingestion, the chemical accumulates in the rodent's liver and continuously decreases vitamin K levels. It prevents the blood from clotting, eventually leading to the rodent's death within 48 hours.

Where to Use Contrac All-Weather Rodenticide

Contrac All-Weather Blox rodenticide is labeled for use in commercial and residential areas, as well as industrial sites like warehouses and production facilities. It can be used in food-processing plants, home garages, office buildings and other spaces both indoors and outdoors. Though the bait degrades slowly in the elements, it should be used in bait stations to keep it fresher for longer. If it's not eaten within 60 days, discard and replace the bait.

Target Pests

Contrac's active ingredient is fatal to most rodents but less toxic to nontarget animals. It's also less harmful to humans and can easily be countered by using vitamin K1 as a treatment. Use Blox rodenticide in tamper-resistant bait stations to keep it out of reach of children, pets and nontarget animals. It works quickly by ingestion and kills and controls Norway rats, house mice, voles, roof rats and other rodents that eat the bait. When used according to the label, it can keep the rodent population under control within two days.

Benefits of Contrac Blox for Rodent Control
