ARE THERE COCKROACHES IN CALIFORNIA?
Cockroaches in California: A Year-Round Concern
Yes, cockroaches live throughout California, and there is no true off-season for them. Southern California's warmer weather means cockroaches can stay active all year, and while Northern California may see fewer outdoor sightings during colder months, they don't completely go away.
Homes, apartments, restaurants, and commercial buildings can experience cockroach activity year-round because they provide consistent warmth, moisture, and food access. So, cockroach season in California never truly ends, and indoor infestations can develop in any month.

REGIONAL DIFFERENCES
Common Cockroaches in Southern California
Southern California's warmer, drier climate creates ideal conditions for several outdoor cockroach species that thrive in heat and arid environments. Turkestan cockroaches are fairly common outside, and American cockroaches (i.e., palmetto bugs) usually appear near drains, crawl spaces, or utility areas. German cockroaches are still the main indoor concern for homes, apartments, and restaurants, while brown-banded cockroaches can also show up indoors and Asian cockroaches may appear around lights or landscaped areas.
REGIONAL DIFFERENCES
Common Cockroaches in Northern California
Northern California's cooler temperatures, higher humidity, and more wooded or damp environments support a somewhat different mix of cockroach species. German cockroaches are usually the indoor species homeowners and renters are most likely to deal with, particularly in apartments, restaurants, and homes with easy access to food or moisture. Oriental cockroaches also show up often around drains, garages, crawl spaces, and other damp areas, while American cockroaches may appear near plumbing or utility spaces and wood cockroaches can wander inside from firewood, mulch, or nearby wooded areas.
ROACH IDENTIFICATION
Common Cockroaches in California
Here's an overview of the most common California cockroach species and where they're typically found:
German Cockroach
Usually found indoors, especially in kitchens, bathrooms, apartments, and restaurants. Danger level: high, because they reproduce quickly and are one of the hardest indoor cockroaches to control. German cockroaches typically do not fly.
American Cockroach / Palmetto Bug
Often found around sewers, drains, crawl spaces, basements, and other damp areas. Danger level: moderate to high, especially when they move indoors or show up repeatedly near living spaces. American cockroaches can fly short distances.
Oriental Cockroach
Common in cool, damp areas like garages, drains, crawl spaces, and shaded outdoor spaces. Danger level: moderate, because they're often drawn to moisture leaks and unsanitary conditions. Oriental cockroaches do not fly.
Turkestan Cockroach
Usually found outdoors around landscaping, foundations, utility boxes, garages, and warm, dry areas. Danger level: moderate, especially when outdoor populations build up close to a home or indoor property. Males can fly, but females usually do not.
Brown-Banded Cockroach
Found indoors in drier areas, including cabinets, closets, furniture, and stored items. Danger level: high, because they can spread beyond kitchens and bathrooms into harder-to-reach areas. Males can fly; females usually do not.
Asian Cockroach
Often found outdoors in grass, mulch, leaf litter, and landscaped areas. Danger level: low to moderate, because they're usually an outdoor nuisance but may enter homes when attracted to light. Asian cockroaches are strong fliers.
Wood Cockroach
Typically found outdoors in firewood, mulch, logs, and wooded areas. Danger level: low, because they rarely establish indoors and usually wander in by accident. Males can fly.
COMMON SIGNS
Signs of a Cockroach Infestation in California
A single cockroach sighting may not mean you have a full-blown infestation. But repeated sightings, especially indoors or during the daytime, warrant a call to get it checked out. Watch for:
- Droppings: Small dark droppings near cabinets, baseboards, pantry areas, or under appliances.
- Egg Cases & Shed Skins: Egg cases tucked into corners and shed skins in hidden areas.
- Musty Odor: A musty smell in enclosed spaces can point to activity.
- Daytime Sightings: If cockroaches are appearing during the day, there may be enough activity behind your walls, appliances, or storage areas that they're being pushed into the open.
Apartments can be especially difficult because cockroaches may move between units through plumbing lines, wall voids, and shared utility spaces. In single-family homes, activity is usually due to moisture, open entry points, outdoor populations near the house, or easy access to food sources inside.
RENTER RESOURCES
California Cockroach Laws & Tenant Rights
For renters, cockroach problems in California apartments can fall under habitability rules. Landlords are generally responsible for keeping rental housing livable, which includes addressing pest issues that affect health or safety.
If you're seeing cockroaches in your apartment or rental, document the problem with photos, dates, and written notes, then report it to your landlord in writing and keep copies of any communication. In multi-unit buildings, cockroaches may be moving through shared walls, plumbing, or utility spaces, so treatment may need to go beyond just one unit to solve the problem.
HOW IT WORKS
Preventing Cockroaches in California
Lasting cockroach control starts with reducing their food, water, and shelter:
01
Seal Entry Points
Seal gaps around doors, pipes, cabinets, and baseboards to limit new activity.
02
Reduce Moisture
Fix leaks under sinks or near appliances, since moisture draws cockroaches indoors.
03
Store Food Properly
Store food in sealed containers, clean up grease and crumbs, and avoid letting trash sit out overnight.
PROFESSIONAL TREATMENT
How to Get Rid of Cockroaches in California
Sanitation and exclusion help, but they may not be enough once cockroaches get more established in a property:
Reduce Food, Water, and Shelter
Seal gaps around doors, pipes, cabinets, and baseboards, and fix leaks under sinks or near appliances.
Watch for German Cockroaches
German cockroaches, in particular, can hide in tight spaces and reproduce very quickly, making DIY control difficult once established.
Address Outdoor Populations
Outdoor species may keep coming back if moisture, mulch, or easy access points around the home are drawing them in.

I've been with Hawx for a few years. They have great customer service. I didn't like that the price went up and got charged without my being notified but I discussed that with them once I realized my auto charge was increased. The current technician I've been getting is Jose. He's pretty responsive and serviced specific areas I needed/requested
