What is the main function of dust formulations like talc or clay in pest management?

The main function of dust formulations like talc or clay in pest management is primarily to detect and estimate pest presence. Dusts can be applied in areas where pest activity is suspected, allowing pest management professionals to monitor the dust's disturbance. When pests come into contact with these dusts, it can help indicate the level of pest activity in the area. Dusts cling to the bodies of pests, making it easier to identify not only the presence of pests but also the specific species and their movements.

While options focusing on repelling pests, acting as bait, or directly killing pests are all legitimate functions of different pest management products, dust formulations serve a crucial role in monitoring and understanding pest infestations. This helps inform future management actions and strategies.
