What Davis's homes mean for your pest control
The median home in Davis dates to 1983, about 43 years ago. That's long enough for trees and shrubs to be fully grown. UC IPM recommends removing limbs within 6 feet of the roof and keeping shrubs at least 2 feet apart and away from walls, because roof rats use branches and dense plants to reach attics. It also warns that stucco running down to the soil can hide subterranean termites, so ask an inspector to look closely at the base of the walls.
About Davis
Davis runs a Resale Program: residential properties must go through either a city resale inspection or self-certification before a sale, with 1-, 2- and 3-unit properties subject to the inspection process, to confirm minimum building, health and fire-safety standards.

Local rules, utilities and conditions in Davis
Davis is served by the Sacramento-Yolo Mosquito & Vector Control District, which covers all of Sacramento and Yolo counties. It offers free mosquito home inspections and free mosquitofish when there's a need, and it may treat yellowjacket nests in the ground, trees or walls. It can't treat nests that have gone into a building's structure or upper floors of multi-story buildings; those need a private pest control company. Call 1-800-429-1022, and report dead birds to 1-877-968-2473. The district says invasive Aedes mosquitoes were first found in Sacramento County in Citrus Heights in 2019.
Davis is in Placer County, where the Placer Mosquito and Vector Control District provides mosquito, tick and yellowjacket control. It responds to reports of heavy yellowjacket activity and notes that most yellowjacket nests in Placer County are underground. For rats, the district offers advice and may inspect severe cases, but it says it does not bait or trap, so rodent work goes to a private exterminator. Reach the district at (916) 380-5444 or toll-free at (888) 768-2343.
Buying or selling in Davis? The termite report is a Wood Destroying Pests and Organisms Inspection Report, and only a Branch 3 licensee working for a registered company can prepare it. The company must deliver it within 10 business days of starting the inspection. Section 1 lists active infestation or damage; Section 2 lists conditions likely to lead to it, like earth-to-wood contact or moisture. You can search the Structural Pest Control Board's database to see whether a property was inspected in the last two years.
Most pest control visits in Davis involve traps, baits, sealing small gaps and pesticide treatments rather than construction. Permits come up when termite or dry-rot damage means replacing structural wood; UC IPM notes that load-bearing repairs may call for an engineer or contractor and building permits. If a termite report recommends structural repairs, check with City of Davis Community Development and Sustainability Department before the work starts.
If rats or cockroaches seem to come up through drains in Davis, check the sewer side. UC IPM says rats can swim through sewers and enter through toilets or broken drains, and oriental cockroaches live in drains and water meter boxes. A exterminator can check cleanout caps and drain gaps; problems in public sewer mains go to City of Davis Public Works Utilities & Operations.
Davis sits on the valley floor, where hot, dry stretches push Argentine ants indoors looking for water, according to UC IPM. Their colonies link into huge supercolonies, so spraying the trail inside won't stop them; outdoor baits that workers carry home work better. Mature street and yard trees also give roof rats a route to rooftops. UC IPM says roof rats routinely travel 300 feet or more for food and are often seen running along fences and utility lines at night.
Flood notes for Davis
The City says FEMA's current flood hazard areas south of I-80 stop at the west levee of the Yolo Bypass; FEMA's flood layer maps roughly 8% of the city as Special Flood Hazard Area.
Renting in Davis?
Only about 44% of Davis homes are owner-occupied, so many residents rent. California landlords must keep rentals free of rodents and vermin (Civil Code §1941.1), and the Attorney General lists pest control for rats, roaches and bed bugs as part of a habitable home. Tenants must keep their unit clean and dispose of trash properly (§1941.2). Report pests in writing and keep copies; landlords can't retaliate for a good-faith bed bug report (§1942.5).
