Why are poisonous baits typically used in minimal amounts?

The use of poisonous baits in minimal amounts is primarily due to the fact that baits are needed only where pests gather. This targeted approach ensures that the bait is placed precisely in locations where pest activity has been identified, maximizing its effectiveness while minimizing unnecessary exposure to non-target organisms or the environment.

By concentrating the bait in areas of pest presence, pest control can be both efficient and ecologically responsible. Using smaller quantities also reduces the risk of accidental ingestion by non-target species, including pets and wildlife. It allows for a more controlled application that focuses on the problem areas, ensuring that the bait is not wasted and effectively disrupts the pest population where it matters most.
