Basement Pests and IAQ

Jeffrey May, Principal Scientist
May Indoor Air Investigations - Tyngsborough, MA

About this program:

This presentation will exam the pests that plague buildings, particularly below-grade; and how those pests can have a negative effect on IAQ and human health. Attendees will learn how to identify and avoid pest problems and the conditions that can lead up to such problems. After attending this session, attendees will have a better understanding of the effect that pests can have on the health of occupants as well as on the integrity of the building structure and contents. Topics will include infestations from mice, shrews, spiders, ants, termites, mold, and microarthropods such at mites. The presentation will examine relationships among occupants' choices, building conditions, building design, and building-maintenance practices, and how these relationships can lead to or exacerbate pest problems. The presentation will be anchored by photographs and practical examples. There will be a brief time at the end for questions and answers, as well as "story swapping."



At this session, you will learn:


1. To understand basement ecology

2. To understand why the control of relative humidity is essential in avoiding pest problems

3. To identify and reduce mouse, shrew, termite, ant, mold, and microarthropod infestations

4. To recognize the importance of building and physical science in pest inspections

5. To gain a deeper understanding of how pest infestations can affect IAQ and human health
