What is one reason tracking powders are particularly useful for house mouse control?

Tracking powders are particularly useful for house mouse control primarily because they can be applied to burrows and areas where mice frequently travel. This application method allows the powder to adhere to the fur of the mice as they pass through, and subsequently, when they groom themselves, they ingest the poison contained in the powder. This behavior makes tracking powders an effective tool in rodent control, as they can be discreetly placed in key areas where mice are active, thus increasing the chances of effective bait uptake.

Also pertinent is that tracking powders are designed specifically to exploit the natural behaviors of rodents, allowing for targeted control without the need for the bait to be ingested directly from a bait station. This ensures a higher likelihood of contact and ingestion, improving the efficacy of the control method.
