Spring in Glens Falls and other Upstate NY communities is a welcome change until pests start showing up. As temperatures rise and snowmelt adds moisture around foundations, insects and rodents become more active and begin searching for food, water, and shelter. Below is a practical guide to the most common spring pests in the region, what to look for, and how Bug-U Pest Control can help stop current activity and prevent future problems.
Why Spring conditions create the perfect storm for pests:
- Warmer days trigger insect emergence and breeding
- Rain and snowmelt increase moisture (a major pest attractant)
- Rodents and overwintering pests move from wall voids/attics into living spaces
- Home maintenance projects can expose entry points pests take advantage of
Common Spring pests (and what to look for)
1. Carpenter Ants
Why they show up: Moisture-damaged wood and damp areas attract carpenter ants.
Signs to watch for:
- Large black ants indoors (especially near windows, sinks, or basements)
- “Sawdust-like” debris (frass) near trim, sills, or baseboards
- Rustling sounds in walls or hollow-sounding wood
2. Termites
Why they show up: Spring is a common time for termite swarmers to appear.
Signs to watch for:
- Swarmer’s (winged insects) near windows or light fixtures
- Discarded wings on sills or floors
- Mud tubes along foundation walls
3. Carpenter bees
Why they show up: Carpenter bees become active in spring and look for exposed, untreated, or weathered wood to drill nesting tunnels.
Signs to watch for:
- Large, “bumblebee-like” bees hovering around decks, eaves, fascia boards, pergolas, sheds, and railings
- Perfectly round holes (about the size of a pencil) in wood
- Sawdust-like debris beneath holes and staining on the wood
- Increased woodpecker activity (they may tear into wood to eat carpenter bee larvae)
4. Ticks
Why they show up: Ticks become active as temps rise, especially in brushy edges and tall grass.
Signs to watch for:
- Ticks found on pets after walks
- Increased tick sightings near wood lines, stone walls, and leaf litter
5. Mosquitoes
Why they show up: Standing water from spring rain and snowmelt creates breeding sites.
Signs to watch for:
- Mosquitoes lingering around shaded, damp areas
- Activity increasing at dusk near patios and entry doors
6. Wasps and Yellow Jackets
Why they show up: Queens start building nests in protected areas early in the season.
Signs to watch for:
- Wasps repeatedly visiting the same corner of siding, soffits, or eaves
- Small starter nests in sheds, under decks, or in attic vents
7. Rodents (Mice and Rats)
Why they show up: Rodents that overwintered in structures keep nesting, and spring food sources can draw them in.
Signs to watch for:
- Droppings in cabinets, basements, garages, or utility rooms
- Scratching sounds in walls/ceilings
- Chewed food packaging or wiring
Spring prevention tips homeowners can do right now:
Reduce moisture
- Fix leaky spigots, pipes, and dripping AC/condensate lines
- Clean gutters and extend downspouts away from the foundation
- Keep crawlspaces and basements as dry as possible
Seal entry points
- Caulk gaps around windows, doors, and utility penetrations
- Add door sweeps and repair torn screens
- Seal gaps where siding meets foundation
Clean up exterior “pest highways”
- Trim branches and shrubs away from the house
- Pull mulch back from the foundation (and avoid piling it high)
- Store firewood off the ground and away from the home
Reduce carpenter bee nesting opportunities
- Paint, stain, or seal exposed exterior wood (especially on decks, fascia, and railings)
- Replace rotting or heavily weathered boards
- Consider adding physical barriers or repairs in areas where bees have drilled in past seasons
Remove food sources
- Keep trash lids tight and rinse recyclables
- Don’t leave pet food out overnight
- Clean up bird seed spills and consider moving feeders away from the home
