Wasp nest, bed bugs, or a swarm right now?
- 1Do not spray a wasp or hornet nest in daylight; colonies sting in numbers and survive.
- 2For bed bugs, stop moving mattresses and luggage between rooms, which spreads them house-wide.
- 3For a termite swarm indoors, bag a few insects for identification and leave the rest.
- 4Then call the companies above and ask for same-day or next-day treatment.

What does pest control cost?
National research range
$100 to $300 per visit
Quarterly recurring service runs about $100 to $200 per visit; one-time treatments and specialty work like termites cost more. U.S. research ranges, not Sunnyvale quotes.
See the full Pest Control cost guideWhat moves the price
- One-time treatment versus a quarterly plan, which almost always costs less per visit.
- The pest itself: general ants and roaches sit at the low end, termites and bed bugs are their own category.
- Square footage and whether the crawlspace, attic, and yard perimeter are included.
- Follow-up visits: ask whether re-treatment inside the warranty window is free.
Ask companies to confirm these in writing. One request above reaches up to three.
Common pests in Sunnyvale
What companies here get called for. 6 of these 8 usually need a recurring plan.
Subterranean termites
Sunnyvale's humid conditions mean the soil stays moist enough to support subterranean termite colonies for most of the year, with no real dry season to slow them down. That persistent moisture lets colonies stay active close to foundations longer than in drier climates, so a preventive inspection is worth scheduling even outside the spring swarm window.
What treatment involves. Liquid soil barrier or a monitored bait system, plus an annual inspection.
German cockroaches
German cockroaches tend to concentrate in kitchens and bathrooms, hiding behind appliances, under sinks, and inside cabinet hinges where they are rarely disturbed. The first sign is usually small dark droppings near food prep areas or a faint musty odor. If you spot one during the day, there are almost certainly more out of sight, so call a pro before the population grows.
What treatment involves. Gel baiting with follow-up visits. One spray rarely finishes it.
Mice
Mice typically enter through gaps at utility line penetrations, under garage doors, and around foundation cracks, then move into wall voids and cabinet spaces. Gnaw marks on food packaging, small dark droppings along baseboards, and scratching sounds at night are the clearest signs. Start by identifying where they are getting in, because trapping alone will not stop new ones from following the same path.
What treatment involves. Exclusion first, sealing entry points, then trapping and monitoring.
Bed bugs
Bed bugs first show up in mattress seams, box spring folds, and the gap between the headboard and the wall, all within a few feet of where people sleep. Rust-colored stains on sheets and tiny shed skins near the seams are early signs. Stop moving bedding and clothing between rooms immediately, since that is the fastest way to carry an infestation into parts of the home that are still clear.
What treatment involves. Heat treatment or a multi-visit chemical program, with follow-up inspection.
Roof rats
Roof rats get into attics through gaps at the roofline, around fascia boards, and where utility lines enter the structure. Once inside, they leave greasy rub marks along rafters and drop dark, spindle-shaped droppings near nesting areas. Check the roofline and soffit vents for chewed edges, because finding the entry point is the step that actually stops the problem.
What treatment involves. Attic and roofline exclusion plus trapping. Baiting alone leaves the entry open.
Fire ants
Sunnyvale's humid conditions keep the soil workable for fire ant colonies through most of the warm months, allowing mounds to rebuild quickly after rain or disturbance. Mounds often appear near driveways, sidewalk edges, and around air conditioning units where the ground is regularly disturbed. Check the yard perimeter carefully before letting children or pets run freely, since mounds can appear overnight.
What treatment involves. Broadcast bait across the yard plus individual mound treatment.
Scorpions
Scorpions turn up in garages, closets, and bathrooms, often resting in dark corners or climbing walls near plumbing. Finding one indoors usually means there is a gap at a weep hole, pipe penetration, or door sweep that it used to get in. Shake out shoes and check towels left on the floor, and look along the base of exterior walls after dark with a UV flashlight, since scorpions fluoresce.
What treatment involves. Perimeter treatment plus sealing at plumbing and weep holes.
Mosquitoes
Mosquitoes rest in dense shaded shrubs, tall grass, and the underside of deck boards during the day, then move toward people in the evening. Any container holding standing water, including clogged gutters, plant saucers, and low spots in the yard, can produce a new generation within a week. Walk your property and empty every standing water source you find before a treatment visit so the pro can focus on resting sites.
What treatment involves. Source reduction plus barrier treatment on resting sites, repeated through the season.
Pest control plans and what they cover
Two pest control quotes rarely cover the same thing. Each service below has the one question that makes quotes comparable.
Recurring general pest plans
A technician treats the outside perimeter and entry points, refreshes bait stations, and treats inside only where pests are active. Most plans include free return visits.
Six of the eight pests covered on this page, including German cockroaches, mice, roof rats, fire ants, scorpions, and mosquitoes, usually need a recurring plan rather than a single visit. A quarterly schedule keeps pressure on those populations continuously, and return visits between services mean you are not waiting three months if something comes back.
What moves the price. Home size, which pests are covered, how often visits come, and the heavier first visit.
Ask before booking. Which pests does the plan cover, and which ones, like termites or rodents, cost extra?
The honest part. Most general plans leave out the expensive problems. Termites, bed bugs and rodent exclusion are usually separate contracts, so read the exclusions before comparing prices.
Termite treatment, liquid or bait
A liquid treatment puts termiticide in the soil so termites cannot reach the wood. A bait system uses monitored stations that termites carry back to the colony.
Subterranean termites are the termite species to address in this area, and both liquid soil barriers and monitored bait systems are used against them. A liquid treatment creates a treated zone in the soil around the structure, while a bait system targets the colony directly. Ask any company you speak with which method they recommend for your specific foundation type and why.
What moves the price. The perimeter length, slab or crawlspace, any concrete drilling, and the bait monitoring visits after.
Ask before booking. Which method suits this house, and what does the warranty require me to pay each year?
The honest part. University of Florida research found baits eliminate the colonies that feed on them, while liquids mainly keep termites out. Bait stations nobody services protect nothing.
Termite warranties and renewals
An annual renewal keeps the warranty in force with a yearly inspection. Retreatment-only means treating again; repair-and-retreatment also pays for new damage up to a limit.
When comparing termite warranty quotes in Sunnyvale, ask each company to hand you the actual warranty document before you sign anything. Confirm whether it covers retreatment only or also repairs, check what voids it such as a missed annual renewal or construction added against the house, and note the damage repair limit in writing so there are no surprises if activity returns.
What moves the price. The warranty type, its repair limit, the size of the structure, and whether it transfers on sale.
Ask before booking. Is this retreatment only, or does it pay to repair new damage, and up to what amount?
The honest part. With retreatment only, every repair bill is yours, and homeowners policies exclude termite damage. Ask for the warranty document itself and what voids it.
Termite inspection for a home sale
A wood destroying insect inspection documents termite evidence, damage and conducive conditions, usually on the NPMA-33 form. VA loans require one in moderate to heavy termite areas.
If you are buying or selling a home in Sunnyvale, ask for the completed NPMA-33 inspection form rather than just a verbal summary, and review what areas the inspector could not access that day. If the inspection turns up evidence of termites and the same company immediately quotes a large treatment, getting a second opinion on that quote is a reasonable step before committing.
What moves the price. House size, crawlspace and attic access, detached structures, and how fast the report is needed.
Ask before booking. Will the report be on the form my lender accepts, and how long does it stay valid?
The honest part. An inspection covers what is visible that day, not what sits behind finished walls. A company that also sells the treatment has a reason to find something.
Rodent exclusion
Finding and sealing the gaps mice and rats use at the foundation, roof line, vents and utility lines, then trapping what is inside. Sealing ends the problem.
Both mice and roof rats are on the pest list for this area, and they use different entry points, mice squeeze through low gaps at the foundation and garage, while roof rats enter higher up at the roofline and soffits. A proper exclusion quote should address both zones with physical sealing work, not just trap placement, since any gap left open will be found again.
What moves the price. The number of entry points, roof and attic access, sealing materials, and follow-up trap checks.
Ask before booking. Is sealing the entry points in this quote, and is the work guaranteed if they get back in?
The honest part. Bait boxes on a recurring plan manage rodents outside but do not stop them coming in. A quote without sealing work is monitoring, not exclusion.
Mosquito and tick programs
A seasonal program treats the shaded foliage where mosquitoes rest and the yard edges where ticks wait, and clears standing water. Each treatment wears off, so it repeats.
Mosquitoes are on the pest list for this area, and a seasonal barrier program treats the shaded foliage and yard edges where they rest between feedings. Because each application wears off over time, the program is repeated through the warm months to maintain pressure. Between visits, emptying standing water around your property is the single most effective thing you can do to reduce breeding on your own.
What moves the price. Yard size, how much dense planting there is, the number of visits, and whether ticks are included.
Ask before booking. How many visits does the season include, and what do you do about standing water here?
The honest part. Barrier treatments reduce mosquitoes but do not eliminate them, and neighbouring yards keep supplying more. Emptying standing water stops breeding, and you can do it yourself.
One-time treatments
A single visit for one specific problem, such as a wasp nest, a pantry infestation or an isolated ant trail, without signing up for a recurring plan.
A one-time treatment makes sense for a specific, contained problem such as a wasp nest, a pantry moth infestation, or an isolated ant mound near the front door. Before booking, confirm with the company that your pest is actually a good fit for a single visit, since German cockroaches and bed bugs almost always need follow-up appointments to fully address, and a one-time price for those often means paying again.
What moves the price. The pest, how established it is, how many rooms or nests are involved, and any follow-up.
Ask before booking. Is a follow-up visit included if the problem comes back within a few weeks?
The honest part. One visit suits some pests and not others. German cockroaches, bed bugs and most ant colonies need follow-ups, so a one-time price there usually means paying again.
What the Sunnyvale climate means for pests
- The climate here is humid for most of the year, and warm humid conditions favour cockroaches, termites and moisture pests, and there is no real seasonal break in activity.
Climate class from DOE Building America county zones.
Six checks before you sign a pest control contract
Pest control is a licensed trade, so start with the state license. The rest is what the contract commits you to.
Check the applicator license
Applicator certification here is handled by the Texas Department of Agriculture. Ask for the license number and the certified applicator's name, then confirm both.
Find the agency's contact details (NPIC)Get an inspection before a termite or rodent price
Plans can be quoted from house size, but termite and rodent work cannot. A phone price before anyone inspects the house is a guess.
Compare the first visit and the recurring price separately
The first service usually costs more than routine visits, so two equal quarterly prices can mean very different totals in the first year.
Read the contract length and how to cancel
Many plans renew automatically or carry a minimum term. Ask how you cancel and whether a fee applies before you sign, not after.
Ask about free return visits
Most plans send a technician back between services if covered pests return. Ask whether that is included and how soon they come.
Ask what product is being used
Ask for the product name, and follow the technician's directions from its label on when people and pets can go back into treated areas.
When to book pest control in Sunnyvale
Spring
Termite swarm season and ant season kick off; the best month for a preventive perimeter treatment.
Summer
Peak mosquitoes, wasps, and roaches; recurring plans earn their keep now.
Fall
Rodents move indoors as nights cool; seal entry points before the first cold week.
Winter
Quietest booking season; good time to negotiate an annual plan.

Frequently asked questions
What does a quarterly pest control plan cover?
A quarterly plan typically covers the exterior perimeter plus interior spots where pests enter, with return visits between scheduled services if covered pests come back. The honest catch is that most general plans exclude the costly problems. Termites, bed bugs, and rodent exclusion are usually separate contracts. Six of the eight pests on this page need a recurring plan, so read the exclusions before comparing prices.
Is pest control expensive in Sunnyvale?
A single pest control visit in the Sunnyvale area typically runs between $100 and $300, depending on the pest, the size of your home, and whether the job covers just the exterior or the interior too. Termites and bed bugs sit in their own pricing category. Submit one free quote request on this page and get exact local numbers from up to three pros.
Does homeowners insurance cover termite damage?
Standard homeowners insurance policies exclude damage caused by insects and termites, so a repair bill lands entirely with you unless your termite warranty covers it. There are two warranty types to compare, retreatment only, where the company treats again if termites return but you pay for repairs, and repair and retreatment, which also covers new damage up to a stated limit. Ask for the actual warranty document, not the sales sheet.
How do I check a pest control company's license in Sunnyvale?
Ask the company for the license number and the full name of the certified applicator who will be on your property. Then confirm both with the state pesticide regulator, which is named and linked further down this page. Also ask whether individual technicians hold their own applicator credentials, not just the company owner, since that is who actually shows up at your door.
How many Sunnyvale companies should I compare?
Comparing at least three quotes gives you a real sense of local pricing and lets you spot gaps in what each plan covers. One request on this page reaches up to three Sunnyvale-area pros at once, so you get that comparison without filling out three separate forms. With 10 companies ranked here and a combined 964 reviews to read, you have enough signal to make a confident call.
Is termite baiting or liquid treatment better?
University of Florida research found that bait systems eliminate the colonies that feed on them, while liquid soil barriers mainly block termites from entering the treated zone. Subterranean termites are the species to focus on in this area, and both methods are used against them. A bait system only works while someone is actively servicing the stations, so ask exactly how often inspections happen before choosing.
