Pest Control in Unalaska, AK

Unalaska is cool, wet and windswept. The average July high is only about 57 degrees, August is the warmest month, and the average January low is around 29. A typical year brings roughly 60 inches of precipitation, including about 82 inches of snow, and October is the wettest month at about 7.9 inches. Around 112 nights a year fall to freezing or below, and the records show no days at 90 degrees or above.

Those numbers are 1991-2020 NOAA climate normals from a nearby weather station, and they should be treated as a guide rather than a forecast. Winters here are only moderately cold, so pests are seldom frozen out for long, and the steady dampness keeps wood, soil and insulation wet. A wet October sends more rodents looking for a dry, sheltered place to spend the colder months.

A practical seasonal routine starts in spring with a look at siding, trim and roof edges for damage. In summer, clear puddles and rain barrels to reduce mosquitoes and check eaves for wasps. In early autumn, before the heaviest rain, seal gaps at doors, vents and pipe entries. Over the winter, keep an eye on storage areas, garages and crawl spaces for droppings, chewed boxes or musty smells.
