You might not see them yet. But trust us, they’re out there.

As spring turns into summer, homes and businesses across New Jersey start facing a wave of new pest activity. From termites to mosquitoes to rodents, May is the month everything starts moving. If you are not prepared, pests will make themselves right at home.

Here is what to expect this month and how to stay ahead.

🐜 1. Carpenter Ants Are Active

Why This Matters: Carpenter ants target moist or decaying wood and can chew through structures quickly.
Where You Will See Them: Inside walls, under window sills, and around wooden decks or trim.
What to Watch For: Sawdust piles and hollow sounds when tapping wood.

🕷 2. Termites Are Swarming

What Is Happening: May is when termites start forming new colonies by flying and mating.
Warning Signs: Discarded wings on windowsills or mud tubes near the foundation.
Why It’s Serious: Termites cause thousands of dollars in damage without showing obvious signs at first.

🦟 3. Mosquito Season Begins

Where They Breed: Anywhere water collects, such as clogged gutters, birdbaths, or empty flower pots.
Why You Should Care: Mosquitoes are more than a nuisance. They can spread West Nile and other viruses.
What You Can Do: Eliminate standing water and schedule monthly yard treatments.

🐭 4. Rodents Return

What Changes in May: Rodents become more active as temperatures rise and food sources increase.
Entry Points: Gaps in siding, garage doors, attic vents, and crawl spaces.
Signs to Look For: Droppings, gnaw marks, and scratching sounds at night.

🐝 5. Wasps and Hornets Are Nesting

When They Start: Early nests begin forming in May as queens search for safe building spots.
Where They Hide: Roof overhangs, sheds, patio furniture, and porch ceilings.
Important: Do not try to spray or remove nests on your own. Call a professional.

✅ What You Should Do This Month
• Schedule a spring pest inspection
• Seal gaps and cracks around your home
• Clear out leaves and debris from gutters
• Cut back bushes and tree limbs touching your house
• Remove any items that collect water outdoors
• Store food and garbage in tightly sealed containers
