Chlorophacinone

What is it and how does it work?

Chlorophacinone disrupts blood-clotting-factor production. It usually requires repeated feeding and belongs to the first-generation anticoagulants. EPA: Restrictions on rodenticide products explains the underlying ingredient or an example product. An active ingredient is only one part of the finished formulation.

What forms and pests are covered?

Example product forms include block bait, soft bait. Example target groups include mice, rats. These are drawn from different labels and references, not a claim that every product treats every listed pest. Check the label for the exact species, life stage and use site.

How is it used in pest management?

This ingredient appears in rodent baits intended for labeled mice or rat control. Use context depends on the exact product and its required bait station. Exclusion, food removal and monitored traps are important non-poison options for households.

Identify the pest, correct food or moisture problems, close entry points where appropriate, and monitor the result. See our integrated pest management guide. A recurring infestation calls for reassessment, not an automatic stronger dose.

What cautions matter?

Direct ingestion can poison pets and children. NPIC also identifies secondary-poisoning concerns for animals eating poisoned rodents. Any suspected ingestion by a child or pet is urgent even if symptoms have not appeared.

Prevent children and pets from contacting stored or applied products. Follow the exact label for protective equipment, ventilation, return intervals, storage and disposal. Do not transfer a pesticide into a drink or food container. Read the label safety guide before selecting a product.

What are its limits?

The station's child resistance, pet resistance and weather resistance must match the labeled location. A refill is not permission to scatter loose bait. These are not wildlife-control recommendations. Never treat bait color or brand name as a reliable way to identify the poison.

The same ingredient in a garden, structural, aquatic or pet product does not make those products interchangeable. This page does not verify current Texas registration, recommend a brand or provide dilution rates, placement quantities or a treatment prescription. Manufacturer sources describe example products, not every formulation.

Where should you check before using a product?

Use the label attached to the exact product you intend to use. Confirm its target pest, permitted site and application method. Check any professional-use restrictions and applicable Texas rules. NPIC explains how to read a pesticide label. Older fact sheets remain useful background, but the current product label takes priority.

For suspected human exposure, follow the label's first-aid instructions and contact Poison Control at 800-222-1222. Call 911 for severe symptoms. For suspected pet exposure, contact a veterinarian immediately.
