If a carpenter ant colony is found outside but causing problems indoors, what should the client be advised to do?

Advising the client to trim trees where branches overhang or touch roofs is important because it addresses one of the primary ways that carpenter ants can gain access to structures. Carpenter ants often use these tree branches as pathways to reach homes and buildings. When branches touch roofs or are too close to the structure, they provide a direct route for ants to enter. Trimming these branches can significantly reduce the likelihood of an infestation, as it eliminates their pathway and access points.

While sealing all entry points is also a good practice, maintaining tree branches and ensuring they do not touch structures is often crucial in preventing an initial infestation. Ignoring the problem or using stronger insecticides might not address the root cause of the invasion and could lead to recurring issues if the ants find other ways to enter. Properly managing the environment around the home helps create barriers and mitigates the risk of infestation effectively.
