After finding adult carpet beetles in a house, what should be the first step when applying IPM principles?

The first step when applying Integrated Pest Management (IPM) principles after discovering adult carpet beetles involves consulting with the customer and inspecting to find what the beetles are feeding on. Understanding the food sources is crucial, as carpet beetles typically feed on natural fibers found in carpets, clothing, and other organic materials. By identifying these sources, you can implement targeted control measures and reduce the likelihood of further infestations.

This approach aligns with IPM's emphasis on prevention and finding the root causes of pest issues rather than immediately resorting to chemical treatments. It promotes a more sustainable and effective pest management strategy that focuses on long-term solutions and minimizes the use of pesticides. Additionally, involving the customer in this process ensures they are informed and can maintain a pest-free environment through proper cleaning and storage practices.

While other methods like sealing entries or spraying insecticides might seem like immediate solutions, they do not address the underlying problem and could lead to recurring infestations if the food sources remain unchecked.
