In pest control strategy, what does 'backfill' refer to?

Backfill refers to the material that is used to fill foundation holes or excavations after construction work has been completed. In the context of pest control, backfilling can be crucial in preventing entry points for pests, such as rodents or insects, into structures. Proper filling of holes and gaps around foundations can limit access to these pests, thereby contributing to an effective pest management strategy. It is part of the broader approach to maintaining the integrity of structures and reducing the likelihood of pest infestations by sealing pathways through which pests could enter.
