The Spotlight: Marysville’s Historic Downtown and the Brickwork Beneath Your Feet (and Above Your Head)
If you’ve strolled down D Street or ducked into one of Marysville’s century-old storefronts lately, you’ve noticed the city is buzzing — and not just with activity for the upcoming Memorial Day weekend markets. This time of year, with warm afternoons finally setting in and wood structures soaking up that Central Valley sun, Marysville’s older building stock becomes ground zero for two pests that love historic architecture just as much as we do: drywood termites and paper wasps.
What Locals Should Know
Unlike subterranean termites that tunnel up from the soil, drywood termites move in through exposed wood — eaves, attic vents, window frames, and the kind of original-growth redwood trim you still find throughout Marysville’s older neighborhoods. May is prime time. Swarmers (winged reproductive adults) emerge on warm evenings, often mistaken for flying ants, and they’re actively hunting new wood to colonize right now.
Meanwhile, paper wasps are already establishing nests under the eaves, porch overhangs, and ornate wooden awnings that give downtown Marysville its character. A queen that started a colony in late April now has workers — and they’re getting territorial. With outdoor dining, the Ellis Lake area, and weekend foot traffic picking up toward Memorial Day, wasp encounters are going to increase quickly.
Practical Tips
- Check your eaves and attic vents this weekend. Look for small, round kick-out holes (roughly the size of a BB) and tiny pellets of frass — those are drywood termite calling cards. Older homes near the Marysville waterfront are especially vulnerable.
- Seal exposed wood before it becomes an invitation. Fresh paint or sealant on window frames and fascia boards genuinely deters drywood termite entry. Don’t skip the undersides of eaves.
- Knock down new paper wasp nests early — and in the evening. A nest smaller than a golf ball with fewer than a dozen cells is manageable now. Wait a few more weeks and that math changes dramatically.
- Don’t leave open beverages or food outside. With Ellis Lake gatherings and patio season underway, sugary drinks are a wasp magnet. Cover cups when you’re not actively drinking.
When to Call a Pro
If you’re finding frass or damaged wood in multiple locations, or if you’ve spotted a termite swarm inside your home, that’s beyond a DIY fix — drywood termite treatment often requires either fumigation or targeted injection work. Similarly, if a paper wasp nest is inside a wall void, under roofing material, or simply in a high-traffic spot where treatment puts you at real sting risk, don’t chance it.
