Homeowners, landlords and anyone buying or selling a house in Moreno Valley, whether you've spotted something or just want to know what to watch for.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Winters around Moreno Valley stay mild, with average lows near 42°F, so colonies keep feeding all year. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.

Cardboard boxes stacked on a garage slab are termite food sitting right on their doorstep. Keep storage on shelves.How treatment works on a typical Moreno Valley home.
Under patios and garage floors, they drill small holes. Treatment goes in through the holes, which get patched afterward. Bait stations are the other main option. They're spaced every 10 to 20 feet. Termites carry the bait back to the colony. The stations are checked on a schedule, often every few months. Across Moreno Valley, on a slab, the crew treats the soil along the outside walls.
Which termites live around Moreno Valley.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. Drywood termites are common around Moreno Valley as well, flying straight into attic framing, eaves and furniture without any soil contact. Look for tiny piles of pellets that look like coarse sand. In Moreno Valley's dry heat, desert subterranean termites can build tubes that hang free from ceilings. They'll eat fences, door frames, anything wooden. The termite you're most likely to meet in Moreno Valley is the desert subterranean termite.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.When termites swarm here.
Across Moreno Valley, desert subterranean termites usually swarm from July through September, around dusk after monsoon storms. Drywood termites around Moreno Valley tend to swarm in late summer and fall. A swarm outside means a colony is nearby. A swarm inside usually means it's in the house. Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves.
Where to look around your house.
Check the garage edges and behind baseboards. Look where pipes come through the floor. Outside, watch for mud tubes behind shrubs. Keep soil and mulch below the slab edge. The same advice applies across the area, from Moreno Valley out to Riverside and San Bernardino. Many homes in Moreno Valley sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks.
A year of termites in Moreno Valley.
- Winter: a good time to book an inspection in Moreno Valley, before swarm season starts. - Summer: swarm season in Moreno Valley, usually after monsoon storms. Watch porch lights at dusk. - Summer: with highs around 96°F in Moreno Valley, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 12 inches of rain a year in Moreno Valley, make sure gutters and downspouts carry water well away from the foundation.
What happens at an inspection.
The inspector walks the outside of the house first. They check the foundation, the soil line and nearby wood. Inside, they check the garage, baseboards, plumbing gaps and the attic. On a slab, they focus on joints, cracks and pipe gaps. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help. Most inspections take an hour or two.
Termites or ants?
- Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Wings: termite wings are all the same length. Ant wings aren’t. - Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Debris: termites leave mud. Carpenter ants leave sawdust.
Getting ready for treatment day.
Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines. Keep kids and pets inside while the Moreno Valley crew applies the product, and ask how long to stay off treated soil. In California, Reticulitermes swarm in the afternoon in spring or fall on clear days after a soaking rain; drywood swarmers fly in daytime during summer and fall; Heterotermes aureus flies late afternoon/early evening in July–September (UC IPM). Drill holes in slabs or patios get patched afterward. Prep is light for liquid treatments and bait stations.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Moreno Valley's dry climate the risk is irrigation and leaky hose bibs rather than rain. Wood chips touching the siding trap the moisture termites are after. Pull mulch back from the foundation and keep the layer thin.
Questions to ask before you sign.
- What do I need to do before and after treatment? - Which termites did you find, and where? - What product or system will you use? - Is the whole foundation treated, or just one spot? - What does the warranty cover, and for how long? - What does the yearly renewal cost?
What affects the price
- Amount of drilling through concrete and patios.
- Liquid barrier versus bait station system.
- Linear feet of foundation to be treated.
- Time of year and how booked up local companies are.
- Local labor rates and licensing requirements.
- Cubic footage under the tent for fumigation.

What's your biggest concern about termites?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way.
What you can do yourself
Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see. Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house.

Simple ways to keep termites away
- Address wood-to-soil contact at steps, fences, and trellises.
- Trim shrubs so foundation walls stay visible and dry.
- Caulk gaps around plumbing and utility penetrations.
- Never leave form boards or scrap lumber in the soil.
- Seal cracks in the foundation and slab.
In an apartment building, termites travel through shared walls and slab joints, so one unit's problem is the whole building's problem.Did you know?

Questions people ask
Is termite treatment safe for kids and pets?
Used according to the label, yes. Soil treatments stay in the ground. Bait stations are locked and buried. Ask for the label and follow any re-entry times.
Will termites come back after treatment?
They can. Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for.
What is the difference between subterranean and drywood termites?
Subterranean termites live in soil and build mud tubes. Drywood termites live inside the wood and leave tiny pellets. Both turn up around Moreno Valley.
Do I have to leave my house during termite treatment?
Not for a soil treatment or bait stations. Fumigation is different. Everyone leaves for two to three days, pets and houseplants included.
Are termite treatment prices going up?
Across Moreno Valley, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Moreno Valley, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
Are termites common in California?
Around Moreno Valley, the usual culprit is the desert subterranean termite.
