The finished poison valley contains 0.0375% of the ingredient.

A good amount of the agent is added at a ratio of 1:4 to make a liquid solution, which is slowly sprayed into the paddy rice with a sprayer and agitated while spraying, so that the liquid is evenly infiltrated into the rice, ready for use, or dried for use.
The prepared baits can be placed in places where rodents are often active, such as rat mouths, rat roads, orchards, or under the bottom of each tree. The baits are inspected once every 1-2 days after being put on bait, and are checked 2-3 times in succession. When baits are eaten or eaten, they must be refilled.
