Timely School IPM #2: Excluding Pests

Last week we promoted SCOUTING for pests.

Today, we want to emphasize ways to EXCLUDE pests. Exclusion is a fundamental way to reduce pests in buildings. Unfortunately, it’s not always a quick and easy job.

Some gaps are easy to see. Improperly fitting door sweeps or gaps along utility lines, for instance.  Others, like gaps along roof lines are harder to locate, and harder to access.

We’ve included some videos and some links to METHODS and exclusion product resources. NOW is a great time to address pest reduction or prevention needs in quiet school buildings. Trade names used herein are for convenience only; no endorsement of products is intended, nor is criticism of unnamed products implied.

While you’re at it, visit our School IPM Best Management Practices Website where we’ve gathered plenty of resources for successful school IPM.

(Above) This gap is obvious, but so often ignored. A proper job of completely sealing this with cement will keep rodents out. Even so, areas like this should be scouted on a regular basis, as pests will find a way to re-use old pathways.
