Termite signs and swarm season in Folsom, CA are marked by a few clues: hollow-sounding wood, winged insects by the windows and mud tubes along the foundation. Any of these calls for an inspection rather than panic. Use Call Now to describe what you found and an independent provider serving 2 ZIP codes around Folsom will answer, with a plan for the next step.
Swarmers: what they are and what they mean
Winged reproductive termites, called swarmers, leave a mature colony to found new ones. They show up in large numbers, often following warm rain, and drop their wings soon after they land. If you find piles of translucent wings on windowsills or by doors, a colony is probably close to the house.
Flying ants can be mistaken for termites. A termite has straight antennae, a thick waist and wings that are all the same length, whereas an ant has elbowed antennae, a narrow waist and front wings longer than its back wings.
Termite signs to look for
- Bubbling or peeling paint without moisture
- Doors and windows that suddenly stick
- Pinhole-sized holes with tiny pellets (frass) beneath
- Mud tubes on foundation walls, piers and sill plates
- Hollow-sounding wood and soft spots in baseboards and door frames
When swarm season happens
Subterranean termites commonly swarm in spring, and drywood termites often swarm in late summer and fall depending on region. The timing varies year to year, so watch weather as well as the calendar.
Do-it-yourself checks
- Tap wood with a screwdriver handle and listen for a hollow sound
- Probe suspect wood to see if it crumbles
- Photograph anything you find without disturbing it
- Look in crawl spaces and garages for mud tubes
- Check wood in contact with soil, such as deck posts and fence boards
What to do next
Do not spray or break mud tubes, because that can make termites move. Photograph the evidence and arrange a professional inspection to identify the species, map the activity and choose a treatment.
Myths and facts
- Myth: one treatment solves everything. Fact: many pests need a follow-up visit and fixes to entry points.
- Myth: spraying the ants you see ends the problem. Fact: baits that reach the nest work better and sprays can scatter a colony.
- Myth: natural means harmless. Fact: any pesticide, natural or not, should be used as the label directs.
- Myth: pests only appear in summer. Fact: rodents, roaches and spiders stay active indoors in winter.
- Myth: a clean house cannot get pests. Fact: pests follow food, water and shelter, and even tidy homes can have them.

Why moisture decides so many pest problems
Cockroaches, silverfish, earwigs, carpenter ants, termites and mosquitoes all depend on water. A slow leak under a sink, a clogged gutter, a downspout that discharges at the foundation or an AC condensate line that drips on the soil can sustain a pest population that no spray will clear.
Fixing moisture is the cheapest and most lasting pest control step. Check under sinks, around water heaters, along the foundation and in crawl spaces, and ask the provider to point out every damp area they find.

Common questions about termite signs and swarm season
How do I tell termites from flying ants?
Check the antennae, waist and wings: straight antennae, thick waist and equal wings mean termites; bent antennae, pinched waist and unequal wings mean ants.
Are swarmers a sign of infestation?
They suggest a colony nearby, either inside or outside the structure. An inspection tells which.
How quickly do termites cause damage?
Colonies can damage wood over months or years, and the damage is often hidden until it is advanced.
Should I treat before buying a house?
Active signs and past treatment both come to light in the wood-destroying insect inspection done during a sale.
Can I prevent termites?
Cut down on moisture, keep wood away from the soil, repair leaks and book inspections regularly.
What does swarm season mean for me?
Use it to inspect your house and deal with any moisture problems.
