Spring hits differently in New Jersey. The cold breaks fast, people open their windows again, and everything feels a little more alive. That’s the good part.
The not-so-good part is that pests come back with it. If you’ve owned a home here for a few years, you know what I mean. This is worth getting ahead of rather than reacting to, so here’s a quick breakdown of what tends to show up and what to do about it.
Ants
Every spring, ant complaints go through the roof across New Jersey. Colonies that spent the winter dormant in soil or inside walls wake up the moment temperatures rise, and they start sending foragers out right away. One scout finds food or water in your home, leaves a trail, and then it’s not just one ant anymore.
Pavement ants, carpenter ants, and odorous house ants are all common in this region, and they’re not the same problem. Carpenter ants will damage wood over time if they’re nesting in it. Odorous house ants are hard to get rid of because of how their colonies are set up. Pavement ants just come in big numbers, fast.
Sealing food, fixing leaks, and closing up entry points all help. But if a colony is already inside a wall or crawl space, surface-level work won’t reach it.

Termites
March through May is prime swarmer season here. Subterranean termites become active as the ground warms, and mature colonies release winged termites to start new ones. Small winged insects clustering near your windows in early spring are not random. That’s worth paying attention to.
Signs tend to be subtle at first: mud tubes on the foundation wall, hollow-sounding wood when tapped, discarded wings left near a window. By the time floors feel soft or walls look wrong, the colony has usually been there for a while. Annual spring inspections are worth scheduling, especially if you’re in an older building or your neighbors have had activity.
Stinging Insects
Wasps, yellow jackets, and hornets start building in spring. A queen that survived winter begins a new nest in March or April, and the colony grows steadily from there. A nest that’s barely visible in April can be a real problem by June.
Common nesting spots include eaves, porch ceilings, deck railings, wall voids, and underground in old rodent burrows. That last one catches people off guard because there’s nothing visible until someone steps too close to the entrance. Small nests in early spring are much easier to handle than a full summer colony. Keep that in mind when you’re doing yard work in April.
Rodents
Rats and mice don’t leave in the winter. They get settled inside walls and foundations, and they stay. Spring shifts things a little since outdoor food comes back, but any established colony inside your home isn’t going anywhere on its own.
Signs are usually sounds first. Scratching or movement in the walls, usually at night. Then you start finding droppings or gnaw marks. The fix that actually holds is exclusion: physically sealing entry points at the foundation, vents, and around plumbing. Traps handle what’s already inside, but sealing keeps new ones from following.
The EPA’s approach to controlling pests safely at home puts non-chemical prevention first. Cut off access, remove food and water sources, then treat whatever’s left inside. It works better than most homeowners expect when they actually follow through on all of it, not just the easy parts.
When to Call Someone
Not every pest situation needs a professional. But spring is a smart time to schedule a home inspection if you’ve had problems before, if your building is older, or if you’re seeing activity you can’t identify. A trained technician can tell you what’s going on and where it’s coming from, which makes every step after that easier.
