Pest Control in San Luis Obispo, CA

The figures here are 1991-2020 NOAA climate normals from a nearby weather station and are a guide, not a forecast. July highs in San Luis Obispo average only about 78 degrees, and September is the warmest month. Around 14 days a year reach 90 degrees or higher. January lows average about 41, December is the coldest month, and roughly 8 nights a year fall to freezing.

Precipitation totals about 18 inches in a typical year, and January is the wettest month at about 3.9 inches. Snow does not appear in the record. The cool, mostly dry warm season and the wetter winter push pests in two directions: toward water sources during dry spells, and toward warm, sheltered spaces once the rain returns.

A yearly rhythm helps. Before the rains, clean gutters, fix drainage and seal gaps. During the wet weeks, check attics, crawl spaces and cabinets under sinks for droppings or damp spots. When the weather warms, treat the perimeter and keep an eye out for wasp nests and ant trails. On the cooler nights, remember that pests keep looking for shelter, so keep firewood away from the walls.
