Think Mosquitoes Die When It Gets Cold in NJ?
You’re Only Half Right
The adults may freeze — but their eggs survive winter just fine.
And they’re already waiting in your yard for spring 2026.

What Actually Happens to Mosquitoes in a New Jersey Winter
Most adult mosquitoes die when temperatures drop below 50°F for several days — but their eggs do not.
In late fall, female mosquitoes lay “overwintering eggs” in anything that can hold water — old tires, clogged gutters, upside-down bottle caps, birdbaths, even folded tarps.
These eggs enter a hibernation-like state called diapause and can survive being frozen solid all winter long.
The moment we get a few warm, rainy days in March or April → boom. Thousands hatch at once.
2025 was one of the wettest years on record in NJ.
That means more mosquito eggs survived this winter than ever before. Spring 2026 could be brutal unless you act now.
How to Stop Next Spring’s Mosquito Explosion — Right Now
1. Eliminate Every Possible Egg Hideout
- Clean gutters before the first hard freeze
- Empty or cover birdbaths weekly
- Drill holes in tire swings & wheelbarrows
- Store tarps & toys so water can’t pool
- Flip over kiddie pools & wheelbarrows
2. Treat Known Breeding Sites with Natural Larvicide
We use cedar oil + Bti (mosquito dunks) — 100% organic, kills larvae only, safe for pets & pollinators.
