The Ants Go Marching… Into Your Boston Basement

Rainfall across New England this month has been relentless—from Southern New Hampshire border to Cape Cod, the ground hasn’t had a chance to dry. And while soggy lawns and puddled sidewalks may be inconvenient for us, they’re a crisis for ant colonies.

When underground tunnels flood, ants are forced to evacuate, and guess where they go? Indoors. Whether it’s your basement, pantry, or bathroom, your dry and warm home becomes the top relocation spot for these six-legged invaders. Especially in older homes common across Massachusetts and New Hampshire, small cracks and foundation gaps become open doors for ants in search of shelter.

But ants are just the beginning. All this rain means:

  • Cockroaches, flushed from sewer systems, head for your pipes and pantries.
  • Spiders crawl out of soaked firewood piles and straight under door frames.
  • Rodents — especially in suburban areas — squeeze into attics and garages to avoid flooded nests.
  • Moisture-loving insects like springtails and pill bugs show up in bathrooms and basements.

This is particularly true after long stretches of damp, 60–70°F days—like we’ve had in Boston and coastal areas this spring — creating a perfect storm for pest invasion.

Protect your New England home before it becomes a shelter:

  • Seal up gaps in the siding, baseboards, and windows.
  • Use dehumidifiers in the basement.
  • Keep food sealed tight and crumbs cleaned up.
  • Book a professional pest control assessment to stay ahead.
