Drywood Termites in Orange County: Do You Have to Tent?
Drywood termites? You may not have to tent.
Book a free licensed inspection with Halo Home Services.
Last week the National Weather Service office in San Diego put inland Orange County under a wind advisory as Santa Ana winds and coastal heat peaked around October 16. Warm, bright fall afternoons like those are when many homeowners in Huntington Beach, Irvine, Anaheim, Costa Mesa, and Mission Viejo first notice small winged insects at a window. According to UC IPM, the University of California's pest management program, the most common sighting of western drywood termites is the winged adults, called swarmers, flying during daytime hours in summer and fall.
The next question is almost always the same: do we have to tent the house? The honest answer is sometimes, but not always. It depends on what a complete, licensed inspection finds. Here is what the science says, so you can make that call with clear eyes.
What drywood termites are
The western drywood termite, Incisitermes minor, is California's second most important termite pest after the subterranean termite, according to UC IPM. It is native and common along the Pacific coast and into the deserts of Southern California.
They live deep inside dry wood and do not need contact with soil.
Colonies are small, usually fewer than 1,000 termites, but they can be widely spread through a structure.
Colonies take years to mature, so damage builds quietly long before anyone sees a swarm.
Signs of drywood termites in your home
UC IPM lists the clues licensed inspectors look for during a drywood termite inspection:
Fecal pellets with six flat sides, often piled on sills, baseboards, or floors. These are diagnostic for drywood termites.
Kickout holes smaller than 2 mm, where termites push pellets out of the wood.
Shed wings near windows, doors, and light sources after a swarm.
Daytime swarmers indoors. Larger dampwood termites, by contrast, tend to come to lights after dark.
Feeding damage in trim, window frames, eaves, attic framing, or wood furniture.
One important limit: pellets alone cannot tell you whether an infestation is still active or how far it extends. UC IPM suggests sweeping up the pellets near a kickout hole and checking again a few days later, keeping in mind that building vibrations can also shake some old pellets loose.
Tenting vs localized treatment: what the science says
UC IPM sorts every drywood termite treatment into two groups, and it advises homeowners to understand the difference before choosing, because the methods are not equal.
Whole-structure treatments treat all infestations at once, including hidden ones. Fumigation with sulfuryl fluoride is the tenting option; residents, pets, and plants leave for several days. Heat is a non-chemical whole-structure option that usually means leaving for hours instead of days.
Localized treatments target a single board or a group of boards. Research cited by UC IPM shows that when the colony is correctly located and the treatment reaches the termites directly, control is high.
The trade-off: with localized treatment, detection accuracy is everything, and UC IPM notes one can never be fully sure every hidden colony was reached. That is why inspection quality and follow-up inspections matter so much.
Neither approach is automatically right. The right choice comes from mapping where the termites actually are.
You don't have to tent if your home qualifies
Halo Home Services offers ADVANCE, a non-tenting, targeted drywood termite treatment system. As described on Halo's ADVANCE page, the process works like this:
Consultation: a short interview about your home's history, past treatments, and additions to see whether ADVANCE fits.
Complete inspection: a licensed inspector maps every area of drywood termite activity and also checks for subterranean termites, wood boring beetles, carpenter ants, and fungus.
Targeted treatment: depending on what is found, this may include direct wood injection, a precise preventive treatment of nearby wood, and a dust application in voids and galleries.
Clean finish: small insertion holes are patched with a similar color.
Ongoing monitoring: yearly inspections help catch new activity early.
Precision is the point. Halo's own termite page is clear that while many drywood colonies can be eliminated by a skilled technician, some homes still need to be fumigated. If your inspection shows activity that a targeted treatment cannot reliably reach, your inspector will tell you so.
Drywood termite checklist for Orange County homeowners
Save a few wings or swarmers in a sealed bag and note where you found them.
Sweep up pellets, then look again in a few days to see whether new ones appear.
Write down the spots: attic, eaves, window frames, door trim, or furniture.
Ask any firm whether its plan is whole-structure or localized, and read the guarantee carefully.
Check the company's license with the California Structural Pest Control Board.
Consider an annual inspection service after treatment, as UC IPM suggests.
DIY vs pro: what homeowners can and can't do
UC IPM does not recommend do-it-yourself drywood termite treatment. The products needed are not available for homeowner use, home-use products are not effective, and figuring out the extent of an infestation takes training and experience. What you can do is document what you see, keep the area tidy so new pellets are easy to spot, and get a licensed inspection before choosing any treatment.
Schedule Your Free Termite Inspection
The first step is always a free licensed inspection, so you know exactly what is in your home before any treatment is discussed. If your home qualifies, Halo's ADVANCE non-tenting drywood treatment means you may not have to tent.
