A spike in temperature isn’t the only weather variable known to drive pest pressure during the summer months. Increased rainfall is another important factor.
Pest behavior is largely driven by three biological needs: food, shelter and water. Of these, water often is the hardest to control. This is especially true in the soggy summer months when rainfall increases and humidity climbs, turning homes that were dry all winter long into waterlogged structures on the brink of moisture intrusion in crawlspaces, overflowing gutters or leaky roofs that are guaranteed to attract pests.
Most insects have an uncanny ability to detect even the smallest amount of moisture, thanks to highly developed sensory organs on their antennae known as hygroreceptors. They use these hygroreceptors to detect microscopic changes in humidity and moisture, leading them to damp areas. To make matters worse, some pests don’t just find moisture; they manage it.
Searching for the telltale signs of moisture intrusion should be a deliberate part of every service call. Moisture-related conducive conditions can include efflorescence on basement walls, water stains on ceiling tiles or drywall, condensation on pipes, deteriorating wood near grade and clogged or overflowing gutters that direct water toward the foundation.
Once located, it’s equally important to properly document the issues for both your client and your own records. Avoid vague notes that don’t provide any useful information, like “moisture present.” Instead, the service record should describe the location, the likely source, any pest activity that was observed in proximity to the condition and recommendations to resolve the problem. Take photographs of problem areas, as company policy allows.
Providing a written list of recommendations, such as fixing a malfunctioning downspout, adding ventilation to the crawlspace or running a dehumidifier in the basement, can be another great way to give your clients actionable steps and reinforce the value of your expertise as a service professional.
