Eradicating All Types of Cockroaches
Although cockroaches don’t sting or bite, that doesn’t mean they can’t pose a risk to humans. Cockroaches can spread bacteria and
viruses that can make people sick. In addition, they are known to get into food sources, which can contaminate your food.
Finding and eliminating cockroaches quickly is important for preventing an infestation.
We can help you get rid of all the most common types of cockroaches, including:
- German cockroaches
- American cockroaches
- Oriental cockroaches
Cockroaches are often found in dark, damp, hidden places in your home. They can often be found near garbage cans and in cracks and
crevices in kitchens, bathrooms, basements, and crawlspaces. Cockroaches breed rapidly, which means a few cockroaches can become a
serious infestation very quickly. You could have thousands of them in just a few weeks.

Keeping Cockroaches Away From Your Home
Knowing how cockroaches get into your house and where they like to hide is helpful for identifying a pest problem and preventing
new pests from getting inside the house. For example, cockroaches often hitch a ride in the house in bags or boxes, so check things carefully
when bringing them into the house. Taking a few easy steps can make your home much less attractive to cockroaches and other pests.
You can prevent cockroaches when you:
- Check the house and seal any holes or openings
- Replace screens in windows and doors that have holes
- Use a dehumidifier to keep the basement dry
- Clean the house carefully, including vacuuming and sweeping the floors
- Store trash in cans with tight lids
- Repair any leaking pipes or plumbing fixtures
At Banner Pest Services, we offer tailored solutions for roach control in San Francisco Bay and East Bay Area. We are happy to provide a free estimate for pest control
services to eliminate cockroaches and any other pests that may have invaded your home and property.
Cockroach Control
Cockroach Questions, Answered
Where they come from, why they're dangerous, and what to expect from professional roach treatment in the Bay Area.
Three species cause almost every Bay Area infestation. German cockroaches are small, light brown, and the most common indoor roach — they reproduce fastest and love kitchens and bathrooms. American cockroaches are large and reddish-brown (often called "water bugs"); they usually come up through plumbing and prefer basements and crawlspaces. Oriental cockroaches are dark, almost black, and thrive in moist spots like laundry rooms and damp garages. Each species responds to different baits and trapping strategies, so identifying the species is always the first step.
Cleanliness helps, but it isn't the only factor — and most infestations have nothing to do with how clean your home is. Cockroaches arrive three main ways: hitchhiking in grocery bags, cardboard boxes, used appliances, or moving boxes; coming up through plumbing from sewers or shared building drains; or migrating from neighbors in attached homes and apartments. Once inside, even moisture under a sink is enough to keep them around. You haven't done anything wrong.
Yes — more than most people realize. Cockroaches don't sting or bite, but their shed skins and droppings are major asthma triggers, especially in children. They also pick up bacteria like Salmonella and E. coli on their bodies as they crawl through drains and garbage, then transfer those onto food and prep surfaces. The CDC officially classifies cockroaches as a public health pest. If anyone in the home has asthma or respiratory issues, treating an infestation quickly matters.
Very fast. A single German cockroach female produces 30–40 eggs in each egg case and can produce several of those across her life. Egg-to-adult is roughly 60 days. So a few hidden roaches in your kitchen at the start of the month can easily become hundreds within a season — and German cockroaches don't have a true off-season indoors. That's why a quick response matters: treatment is dramatically easier when the population is small.
Less than you'd think. Modern cockroach treatment uses targeted gel baits and dusts placed in the cracks and crevices roaches use — not blanket sprays. That means in most cases you don't need to clear the kitchen, wash dishes, or vacate the house. Your technician will let you know if anything specific needs to move before they start. It's a big change from the old-school "fog and evacuate" approach, and it works much better.
Foggers and store-bought sprays push roaches deeper into walls and adjacent rooms instead of killing the colony. You hit the visible ones, but the egg cases and hidden adults survive — then re-emerge, often spread across more of the house. Professional bait-based treatments work the opposite way: roaches eat the bait, return to their hiding spots, and the active ingredient passes through the population, including the ones you never see.
For a typical home infestation, you'll see a sharp drop within the first week, and the colony is usually eliminated within 2–4 weeks of the initial service. Severe infestations or established German roach populations can take a follow-up visit to fully resolve, which is why we schedule active cockroach jobs on a tighter cycle than our standard quarterly visits — usually a 2-week follow-up rather than 90 days.
This is one of the most common Bay Area situations — and treating just your unit usually isn't enough on its own, because roaches move between units through shared walls, plumbing chases, and electrical runs. Banner handles a lot of multi-unit work and can advise your property manager on a building-wide approach. If you're a tenant, document the issue with photos, notify the landlord in writing, and have them call us. Many Bay Area landlords engage Banner directly to handle apartment and multi-unit treatments.
