Application Rates and Placement

Check the pouch size before application. The number of pouches required differs between FirstStrike 10-gram bait and FirstStrike 40.

Target Rodent 10-Gram Pouches per Placement 40-Gram Pouches per Placement Typical Placement Spacing
House mice 1 pouch; up to 4 at locations with very high activity 1 pouch 8–12 feet
Norway rats and roof rats 9–43 pouches 2–11 pouches 15–30 feet

Maintain fresh bait for 15 days for mice or 10 days for rats, or until signs of activity cease, as directed by the label. Replace spoiled or contaminated bait promptly. These are placement rates, rather than application rates per acre or 1,000 square feet.

Position bait where rodent activity is evident, such as along walls, near gnawed openings, and in concealed travel areas. Reduce competing food sources and conditions that support infestations.

Use Restrictions and Handling

  • Bait stations are mandatory for outdoor, above-ground applications. Tamper-resistant stations are required wherever children, pets, or other nontarget animals could access bait.

  • Do not broadcast bait, place it in rodent burrows, or apply it directly to food or feed crops.

  • Prevent contamination of food, feed, water, and food-handling equipment.

  • Wear waterproof gloves, long pants, shoes, and socks when handling the product.

  • Collect visible rodent carcasses and leftover bait according to label directions.

  • Store in the original container in a cool, dry location inaccessible to children and pets.

FirstStrike is extremely toxic to mammals and birds. Predators and scavengers can also be poisoned by eating rodents that consumed the bait.

State Registration or Purchase Considerations
California FirstStrike Soft Bait is actively registered but is a California restricted material. Most uses, including ordinary residential use, are prohibited; specified exemptions and other requirements apply.
Connecticut Difethialone products are state restricted-use pesticides as of January 1, 2026. Purchase requires appropriate applicator certification through a registered restricted-use dealer.
South Carolina State restricted-use pesticide. Sales are limited to properly certified applicators through licensed pesticide dealers.

Confirm current destination-state requirements before purchase or application.

Benefits of Using FirstStrike Soft Bait

Benefit Practical Advantage
Palatable, wax-free formulation Provides a soft bait option that encourages rodent feeding.
Maintains integrity in hot environments Helps bait retain its form in warm service locations.
Flexible placement amounts Allows applicators to adjust pouch quantities within labeled rates.
Compatible with bait rods and feeding devices Supports secure bait placement inside suitable stations.
Optional wrapper removal When used with a device that secures unwrapped bait inside a station, removing the paper can reduce wrapper debris.

These features support practical bait-station servicing and professional rodent management.

Always read and follow the complete product label.

How quickly does FirstStrike Soft Bait work?

Norway rats and house mice may consume a lethal dose during one night of feeding. The first dead rodents generally appear about four to five days after feeding begins. Complete control takes longer and depends on bait consumption and infestation size.

Do I need to remove the paper wrapper?

No. Pouches can be secured in an appropriate bait station. The U.S. label also permits wrapper removal when the exposed bait is held securely in a feeding device inside the station.

How many pouches are in a 16-pound pail?

A 16-pound pail contains approximately 726 ten-gram pouches or 182 forty-gram pouches, depending on the version. Products are sold by weight, so pouch counts are approximate.

Is FirstStrike Soft Bait safe around pets?

Pets must be prevented from accessing the bait and poisoned rodents. If a pet eats bait, contact a veterinarian immediately and have the product label available. Difethialone can cause serious bleeding; vitamin K₁ treatment must be directed by a medical or veterinary professional.

How should unused bait be stored?

Keep bait in its original container in a cool, dry place inaccessible to children and pets. Follow the label’s storage and disposal instructions.
