The Best Time to Start Mosquito Treatments (Hint: Before Summer)

Every spring, we get a wave of calls from Bergen County homeowners who spent Memorial Day weekend getting eaten alive in their own backyard — and are now desperately looking for relief. We help them, absolutely. But if they'd started a mosquito program six weeks earlier, they would have spent that holiday weekend actually enjoying their yard. This is one of the most common mistakes we see from Hawthorne to Ridgewood to Wyckoff.

Why Timing Matters So Much

Mosquitoes don't just appear from nowhere in June. They overwinter as eggs in soil and standing water, and the first population surge in North Jersey happens much earlier than most people realize — typically in early spring when temperatures consistently hit 50°F. By the time you're noticing mosquitoes at your Fair Lawn cookout or in your Glen Rock backyard, the first generation has already hatched, mated, and laid a second round of eggs.

Starting your program before that first hatch breaks the reproductive cycle early, which means you're dealing with a much smaller population all season long rather than playing catch-up against an established one.

What Our Botanical Mosquito Program Does

Pops uses plant-derived botanical treatments that are highly effective against mosquitoes but gentle on beneficial insects, pets, and people. Here's how it works:

• Resting area treatments: We mist shrubs, tall grass, ground cover, and the underside of decks — where mosquitoes spend most of their day hiding from heat.
• Standing water management: We identify and treat sources of standing water on your property where eggs are laid.
• Monthly maintenance visits: We return every 3–4 weeks to re-treat as the residual fades, keeping populations low all season.

When Should You Start?

In Bergen and Passaic County, we recommend scheduling your first treatment in late March or early April — before you're seeing mosquitoes regularly. That's typically right around the time trees start budding and you're getting consistent daytime temps in the mid-50s. Wooded towns like Wyckoff, Mahwah, and Midland Park tend to see mosquito pressure earlier than more developed areas, so residents there should err on the earlier side.

If you're reading this in May or June, don't worry — it's not too late. A program started mid-season will still make a significant difference within the first few weeks. But the earlier you start, the better your entire summer will be.

A Few Things You Can Do Right Now

• Dump any standing water in flower pots, buckets, tarps, or clogged gutters.
• Keep grass trimmed short — tall grass is prime mosquito resting habitat.
• Consider a mosquito-dunking treatment for ornamental ponds or water features.
• Schedule your first treatment before the weather really warms up.
