Pests in Union
What we deal with most around Union, CA
With mild weather and regular rain, Union City sees steady ant activity, especially after wet spells when colonies move toward dry indoor spaces. Spiders take up residence in garages, window frames and outdoor furniture, and cockroaches use plumbing and drains to work their way into kitchens and bathrooms.
Termites and carpenter ants like wood that stays damp, so leaky faucets, poor drainage and fence boards touching soil are common starting points. Rodents such as mice and rats look for shelter in attics and walls as the weather cools, and wasps may build under eaves. Near park edges, mosquitoes and ticks can be more of a nuisance, and fleas hitchhike on pets.
Weather and pests
How Union's weather affects pest activity
Union City stays comfortable through most of the year. July highs average only about 78 degrees, and September is the warmest month. January lows come in near 43 degrees, and December is the coldest month. The figures come from 1991-2020 NOAA climate normals at a nearby weather station, and they are a guide, not a forecast.
A typical year brings about 16 inches of precipitation, and February is the wettest month at roughly 3.2 inches. Snow does not fall in measurable amounts. Only about 12 days a year reach 90 degrees or higher, and about 3 nights drop to 32 degrees or below.
Cool, damp winters and mild summers spread pest pressure through the year. Rain and damp soil favor ants and termites, and cool nights push rodents toward buildings. Warmer spells bring spiders, wasps and mosquitoes into the yard. Keep gutters and downspouts working, seal gaps around pipes and vents, and keep wood and mulch away from the foundation to lower your risk.
How we fix it
Pest control services in Union
Ant treatment in Union
Ants are among the most common calls we get in Union, from sugar ants in kitchens to carpenter ants in damp or damaged wood. Activity climbs quickly once spring temperatures arrive. We find the trails and the nest, treat where the colony lives and follow up so they do not simply return.
Rodent control in Union
Mice and rats look for food, warmth and shelter, and Union buildings offer plenty of all three. They can be a year-round issue. Our exclusion-based approach combines inspection, sealing entry points, trapping and monitoring, so you fix the reason rodents got in, not only the rodents you can see.
Termite control in Union
Termites are a quiet threat because damage often goes unnoticed for years. A yearly inspection costs little next to the cost of repairs. We inspect for mud tubes, damaged wood and moisture problems, then treat with a plan matched to how your Union home is built.
Cockroach control in Union
Cockroaches are hard to get rid of with store-bought sprays. We locate the hiding places, treat cracks, crevices and voids, and use monitoring so we know the treatment worked. It is a common request in Union apartments, restaurants and older homes alike.
Spider control in Union
Most spiders are harmless, but nobody wants webs around the door or a spider in the basement. We remove webs and egg sacs, treat the perimeter and reduce the insects that spiders feed on, which keeps them from coming back.
Mosquito control in Union
A little standing water is all it takes for mosquitoes to breed in Union. We treat resting areas in your yard, help you find and remove breeding sites and schedule visits through the warm season so you can use your yard again.
