What physical signs indicate that a house has had a termite treatment?

The presence of visible chemical barriers or treatment stickers is a clear indication that a termite treatment has been performed on a house. Chemical barriers are often installed around the foundation to prevent termite entry, and treatment stickers are typically placed in various locations to denote that a specific area has been treated for termites. These treatments act as preventative measures, ensuring that termites do not infest the property.

In contrast, fresh wood installations do not necessarily signify prior termite treatment, as they may simply indicate renovations or repairs made regardless of pest control status. Characteristic droppings on the floor point to active infestations rather than prior treatments, as they are a sign of current termite activity. High levels of humidity indoors, while potentially conducive to termite activity, do not indicate treatment and may instead suggest environmental conditions that could support an infestation. Thus, visible chemical barriers and treatment stickers are the most direct evidence of a termite treatment having taken place.
