How can you identify the presence of a spider infestation in a structure?

Identifying the presence of a spider infestation often relies on visible evidence of their activity, which primarily includes webs and egg sacs. Spider webs serve as a significant indicator of their presence; they are constructed for hunting and residing. The presence of silk in corners, behind furniture, or in less disturbed areas can suggest a spider's habitat. Additionally, finding egg sacs can signify that a reproductive cycle is occurring, indicating a more established infestation.

While spotting live spiders is helpful, it may not provide a complete picture of the extent of an infestation since spiders can be elusive and may not always be easily visible. Unusual odors and noises can be associated with other pests and are not reliable indicators of spider presence. Therefore, locating webs and egg sacs is the most definitive method to confirm that spiders are living and reproducing in the structure.
