Selection of Treatment Area: Determine areas where rats and/or mice will most likely find and consume the bait.

Protect bait from rain and snow. Remove as much alternative food as possible.


Application Directions: Each Just One Bite® II Bait Chunk weighs 2-oz.

Rats: While wearing gloves, apply two to eight 2-oz blocks at each placement location in infested areas. For burrow applications, insert one to two 2-oz pieces of block at least six inches into each active burrow. Check treated burrows each morning and evening to make sure that baits have not been pushed out of burrows. For above ground treatment, space bait placements 15 to 30 feet apart. Maintain an uninterrupted supply of fresh bait for 10 days or until fresh signs of rat activity cease to appear.

Mice: While wearing gloves, apply one 2-oz chunk per placement in infested areas. Space placements at 8 to 12 foot intervals. Maintain an uninterrupted supply of fresh bait for 15 days or until fresh signs of mouse activity cease to appear.

Follow-Up: Replace contaminated or spoiled bait immediately. Wearing gloves, collect and dispose of all dead animals and leftover bait properly. To prevent re-infestation, eliminate food, water, and harborage as much as possible. If re-infestation does occur, repeat treatment. Where a continuous source of infestation is present, establish permanent bait stations and replenish bait as needed.
