What condition is most likely to lead to a springtail infestation in buildings?

Springtails are tiny insects that thrive in moist environments, and one of the primary conditions that can lead to a springtail infestation is constant high humidity. These pests prefer damp conditions, which are often found in areas with high moisture levels, such as basements, bathrooms, or near plumbing fixtures. When the humidity is maintained consistently at high levels, it creates an ideal habitat for springtails to reproduce and thrive.

In contrast, conditions associated with high temperatures, consistent low humidity, or frequent cleaning do not favor the presence of springtails. High temperatures can cause moisture levels to decrease, deterring springtail survival. Low humidity does not support their reproductive cycle or habitat needs effectively. Meanwhile, frequent cleaning can reduce the organic matter and moisture that springtails rely on for food and a suitable living environment, potentially helping to control their populations rather than encourage them.

Therefore, the combination of constant high humidity directly creates the favorable conditions needed for springtail infestations in buildings.
