Pest control in Sacramento, CA, answered 24/7

What pests are most common in Sacramento, CA?

The pests that most often bring Sacramento homeowners to the phone are Argentine ants, roof rats, subterranean and drywood termites, yellowjackets, German cockroaches and spiders such as the western black widow. Ground squirrels and voles matter near levees and open grass. Which one you meet depends on the season and the age of the house.

UC Integrated Pest Management (UC IPM) calls the Argentine ant the most common outdoor ant in California. It is about 3 mm long, dark, and does not sting, and its workers can travel up to 100 feet from the nest to reach food, water and shelter inside a building. UC IPM also lists the roof rat as present in almost all California cities, nesting above ground in shrubs, trees and dense vegetation such as ivy.

Many of these pests leave early signs. Catching them while they are a trail, a sound or a few shed wings is usually simpler than waiting for a full colony. These are the signs that most often start a call:

• A thin line of small dark ants at the kitchen sink or bathroom drain in a dry month: ant control.
• Scratching or running in the ceiling, or droppings near the attic hatch: rodent control and roof rat exclusion.
• Winged insects at a window or a scatter of shed wings on a sill, especially after the first autumn rain: termite control.
• Wasps entering a gap in the siding, a hole in the lawn or the eaves in late summer: yellowjacket removal.
• Roaches in the kitchen or bathroom of an apartment or rental: cockroach control.
• Burrow mounds in open grass near a levee or park edge: ground squirrel and vole control.

How do Sacramento's dry summers and wet winters change the pests you see?

Sacramento has a Mediterranean climate: hot, dry summers and mild, wet winters, with about 18 inches of rain in an average year, most of it from November to March. Ants and other pests look for water indoors when the ground is dry, and termites move when the first rains soak the soil.

Averages for 1991 to 2020 put the typical high near 87 F in June, 92 F in July and 91 F in August, with little or no rain from June through September. The first 100 F day usually arrives around early June. Cold ocean air drawn through the Sacramento-San Joaquin Delta, the Delta breeze, can cool evenings noticeably, but the yard stays dry.

Use the table as a rough guide. Timing shifts from year to year, and the technician will tell you what the calendar means for your house. The month-by-month pest calendar goes deeper.

How do Sacramento's neighborhoods and house ages shape pest problems?

House age tells you where to look. Downtown, Midtown, Curtis Park, Land Park and East Sacramento have homes from the early 1900s to the 1930s, often with raised floors and mature trees. Postwar tracts in Carmichael and Rosemont, and newer ones in Natomas and Elk Grove, bring different entry points.

The old core was built first. Alkali Flat dates from the 1850s and 1860s, Midtown holds Victorian mansions and Craftsman bungalows, and Curtis Park, Land Park and East Sacramento's Fab 40s fill out the 1920s and 1930s. Homes of that age often have raised floors, which is why a crawl-space pest inspection is a regular part of an older-home visit. Mature elms, oaks and ivy also give roof rats an easy route to the roofline.

Postwar neighborhoods such as Carmichael, Arden-Arcade, Rosemont and Citrus Heights grew from the late 1940s through the 1970s, and North Natomas and Elk Grove were built mostly after 1998. Those tract homes raise different questions about slab-home pest control. Near the American and Sacramento rivers, the American River Parkway runs 23 miles through the county, and the vegetation along it is good habitat for wildlife and rodents alike.

• Old core and 1920s to 1930s bungalows: crawl-space pest control and termite checks.
• Postwar and newer tracts: slab-home pest control and perimeter plans.
• Apartments, rentals and the Railyards: cockroach control and bed bug treatment.
• Restaurants, offices and warehouses: commercial pest control.

How can you check a pest control company's license in California?

Use Verify a License on pestboard.ca.gov, the website of the Structural Pest Control Board. It leads to the Department of Consumer Affairs License Search, where you choose Structural Pest Control Board and search by name, business name or license number. The Board's Enforcement Unit at (800) 737-8188 can also confirm that a company is registered.

California licenses structural pest work in three branches: Branch 1 is fumigation, Branch 2 is general pest, and Branch 3 is termite work. A license is limited to the branch or branches the person qualified for by exam, so a company that treats ants is not automatically cleared to fumigate a house.

When you call Sacramento Pest Control, a local technician comes out, and you are welcome to ask for the license number of the company doing the work. The About page explains how that works, and the termite inspection report guide shows what to expect on paper.

Is Sacramento Pest Control the same as the Sacramento-Yolo mosquito district?

No. The Sacramento-Yolo Mosquito and Vector Control District is a public agency whose authorized work is mosquito and vector control, with yellow-jacket control running July through September. Sacramento Pest Control is a separate private call line that arranges service for homes and businesses. We are not the district and are not affiliated with it.

The district began in 1946 as the Sacramento County-Yolo County Mosquito Abatement District and took its current name in 1990. West Nile virus is now a major public-health focus for it. Its office is at 8631 Bond Road in Elk Grove, and its number is (800) 429-1022.

If your question is about mosquito breeding in a public ditch or a neglected pool, the district is the right call. If it is about the yard, the attic or the kitchen, that is mosquito control or one of our other services. The district versus pest company guide sorts out which is which.
