Someone finds pale insects in a pile of wood dust on a Point Loma windowsill and searches “termite larvae.” Termites do not grow as maggots. Drywood and subterranean termites have incomplete metamorphosis: eggs, nymphs, then soldiers and reproductives. The word is still the search. The inspection has to name the insect that is actually in the wood.
What you are probably looking at
UC IPM’s western drywood termite notes describe insects that live deep in wood and are rarely seen until they swarm. Colonies are small, often fewer than 1,000 individuals, and take years to mature. The sight people get is usually swarmers in summer or fall, or fecal pellets pushed through kickout holes.
Those pellets have six hexagonal sides. Kickout holes are less than 2 millimeters across. UC IPM says pellets alone cannot tell you whether the infestation is active or how far it runs. Cleaning the pile and watching whether new pellets appear is a homeowner check, not a clearance.
Nymphs are cream-colored and can look “larval” if you have no other word for a soft insect in wood. They are not fly maggots, and they are not the eggs page. Eggs are not what you scoop off a sill. If you are looking at tiny white objects and asking whether they are eggs, use termite eggs at home. This page owns the pale-insect-in-frass moment.
Swarmers are winged adults. They are the most common drywood sighting, daytime in summer and fall along the coast and into inland valleys. Flying ants get mixed in constantly. Compare flying ants vs termite swarmers before you treat a window as a colony map.
Carpenter ants, wood-boring beetles, and dampwood termites produce different debris. Dampwood pellets are football-shaped without the clear hexagonal ridges. Beetle frass is often more powdery or pellet-like without the six sides. UC IPM says final pellet ID may need an expert. A phone photo of dust is not a WDO report.
Subterranean termites nest in soil and build mud tubes. If you have tubes on a foundation in El Cajon or a slab in Mira Mesa, that is a different species story than drywood pellets in an attic beam. Drywood vs subterranean termites in San Diego keeps those jobs apart.
What a pile of dust cannot confirm
Activity, species, and extent are three different questions. Pellets answer none of them by themselves. UC IPM is direct: inspecting and figuring out the extent of a drywood infestation requires experience and is best done by a professional. California’s minimum inspection is a visual search of accessible areas. Hidden galleries can sit behind drywall and stucco.
Do-it-yourself treatments are not recommended. UC IPM states products needed to control drywood termites are not available for general public use. Orange oil and similar spot products have mixed published results. A consumer spray on a sill does not reach insects inside a beam.
Whole-structure treatments (fumigation or heat) and localized treatments are different scopes. Fumigation is Branch 1, sulfuryl fluoride, occupants out, re-entry only after the licensee posts clearance. Localized work is still licensed, usually Branch 3 for wood-destroying organisms. Pest Pros San Diego does not fumigate, drill, or inspect. We match you with companies that hold the right branch for the proposal.
Ask for a written inspection before any treatment. Compare at least three reports if the quote is structural. Check the firm on the SPCB license search. The name on the license must match the name on the quote.
Termite inspection is the first service path. Termite treatment is the path once a company has named the infestation and the method. Do not skip the report because a YouTube video called the insects larvae.
If the only evidence is swarmers on a single day and no pellets return, say that. Swarmers can come from a neighbor’s structure or from a fence. The inspector still has to look at your wood.
What to document before anyone drills
Photograph the insects on a pale surface with a ruler. Photograph the pile, the kickout hole if you can see it, and the room. Note whether the wood is structural, trim, or a picture frame. Point Loma bungalows, older North Park craftsman attics, and Encinitas additions fail in different places. The inspector needs the address, not a generic “termite larvae” label.
Do not paint over pellets or caulk a hole before the visit. You will hide the activity check. Do not soak the wood with a store product. Residue complicates the next inspection and does not replace detection.
Mention moisture. Dampwood termites want wet wood. A roof leak in a coastal house can be a moisture repair plus insects, not a tent. UC IPM handles dampwood primarily by fixing moisture and replacing damaged wood once correctly diagnosed.
For what termites look like in this county, what do termites look like in San Diego is the broader ID page. This page stays on the larvae/nymph confusion and the pellet pile. Termite droppings or sawdust is the debris comparison when you have dust and no insect.
Bring the photos to the call. Pest Pros San Diego will not identify a species from a texted picture as a lab. The matched Branch 3 company writes the findings.
When to call us
Call when pale insects show up with wood dust, when hexagonal pellets return after you sweep, or when swarmers appear inside. That is a wood-destroying inspection, not a kitchen spray. Call us at (858) 400-6561 and we’ll match you with a licensed local pro.
