Much of Union County sits right up against tick country. The Watchung Reservation runs through Mountainside, Summit, Berkeley Heights and Scotch Plains. The Rahway River parkway threads through Cranford, Kenilworth and Union, and the Passaic River lines the western edge. Wooded backyards in Westfield and New Providence connect to all of it. That’s great for deer, raccoons and the ticks that ride on them. It’s also why flea and tick control in Union County is a yard problem first and a house problem second.
This guide covers which ticks you’ll find, when they’re active, how fleas end up inside, and what actually reduces both around your home.
The Ticks You’ll Find in Union County
New Jersey has several tick species, and three show up in Union County yards most often:
| Tick | How to recognize it | Why it matters |
|---|---|---|
| Blacklegged (deer) tick | Tiny, dark legs; nymphs are the size of a poppy seed | The main carrier of Lyme disease, anaplasmosis and babesiosis in NJ |
| Lone star tick | Reddish-brown; adult females have a single white spot on the back | Aggressive biter, increasingly common in New Jersey |
| American dog tick | Larger, brown with white or gray markings | Common on dogs and along grassy edges |
The Asian longhorned tick is also worth knowing about. It was first identified in the United States in New Jersey, and it can build up large numbers on pets and livestock.
When Ticks and Fleas Are Active
Tick season in Union County isn’t just summer:
- Spring to early summer: blacklegged tick nymphs are most active, and they’re small enough to miss. Most Lyme infections come from nymph bites.
- Fall: adult blacklegged ticks become active again from October into early winter. Hunters, hikers and anyone doing fall yard cleanup get bitten.
- Winter: adult ticks can still be active on days above freezing.
Fleas follow a different calendar. Outdoors, they’re most active in warm, humid months. Indoors, once they’re established in carpets and pet bedding, they breed all year.
How Fleas and Ticks Get Into Your Yard
Ticks don’t travel far on their own. They wait on grass and brush for a host to walk by. Animals carry them into your yard:
- Deer crossing from wooded lots and the reservation edges
- Raccoons, opossums and groundhogs living under decks, sheds and porches
- Mice and chipmunks, which are major hosts for young blacklegged ticks
- Stray and outdoor cats, which also carry fleas
That’s why wildlife control and tick control overlap. A raccoon family under the deck or a groundhog burrow beside the shed brings fleas and ticks right to the house. If animals are already living under or in your home, read our guides to raccoons in the attic and groundhogs in New Jersey.
Fleas Indoors: Why They’re Hard to Shake
Most household fleas are cat fleas, and they live on dogs as happily as cats. The adult flea on your pet is only a small part of the problem. Flea eggs fall off into carpets, couches and pet beds. Larvae develop in those fibers, and the pupae can sit dormant for weeks before hatching when they sense warmth and movement.
That’s why a house can seem clear after a pet treatment and then flare up again weeks later. It’s also why moving into an apartment where a previous tenant had pets can mean fleas, even if you don’t have animals.
Signs of fleas indoors:
- Pets scratching, biting at their fur or losing hair at the base of the tail
- Small dark specks (“flea dirt”) in pet bedding that turn reddish when wet
- Bites on ankles and lower legs
- Fleas jumping on light-colored socks when you walk across the carpet
Reducing Ticks in Your Yard
You can’t make a yard tick-free, especially one backing onto woods. You can make it much less friendly:
- Keep the lawn short, especially along edges and paths.
- Remove leaf litter in fall, where ticks shelter through winter.
- Create a barrier. A strip of wood chips or gravel about three feet wide between the lawn and wooded areas keeps ticks from migrating into play areas.
- Move play sets, patios and seating away from the woods edge and into the sun.
- Stack firewood neatly and keep it off the ground and away from the house. Woodpiles shelter mice, which carry young ticks.
- Keep wildlife out from under decks and sheds. Close off openings once you’re sure no animals are inside.
- Don’t feed wildlife, including birdseed spilled under feeders, which draws mice and chipmunks.
Reducing Fleas Inside
- Treat pets on schedule. Ask your vet about year-round flea and tick prevention for dogs and cats.
- Vacuum often in pet areas, under furniture and along baseboards, and empty the vacuum outside.
- Wash pet bedding in hot water regularly.
- Treat the house and the pet at the same time. Treating one without the other lets fleas cycle back.
Protecting Your Family
After time in wooded areas or yard work near the woods edge, check for ticks: behind the knees, waistband, underarms, scalp and behind the ears. Check pets before they come inside. Shower soon after coming in. If you find an attached tick, remove it with fine-tipped tweezers close to the skin, and talk to your doctor if you develop a rash, fever or flu-like symptoms afterward. The NJ Department of Health has detailed guidance on tick-borne illness.
When to Call for Professional Flea and Tick Control
Call when ticks keep turning up on family members or pets despite yard work, when a flea problem keeps coming back after pet treatments, or when wildlife is living under or around your home. We’ll inspect the yard and house, find where ticks and fleas are concentrated, and recommend a treatment plan. See our pages on tick control and flea control.
Tick control in Union County yards starts in the same places: the lawn edges where grass meets woods, brush, stone walls and leaf litter, where ticks wait for a host. Cutting that cover back and treating those edges through the active season lowers the numbers. Fleas need the house and the pets treated together. Clearview Pest Control is based in Bayonne, NJ, at 182 West 31st Street. For questions about fleas or ticks, call 201-706-7437.
For everything else, including rodents, termites and wildlife, see Union County pest control. If you live near the reservation in Berkeley Heights, see our page on Berkeley Heights pest control. And if you’re not sure what’s living in your attic or walls, start with our guide to signs you need wildlife removal.
Flea and Tick FAQ
Are ticks active in Union County in the fall?
Yes. Adult blacklegged ticks are active from October into early winter, and they can be out on any day above freezing.
Can ticks live inside my house?
Most ticks don’t survive long indoors. Fleas are different and can live and breed inside year-round once established.
Why do I have fleas if I don’t have pets?
They may have come from a previous tenant’s pets, from wildlife living under or in the house, or from stray cats around the yard.
Do I need to treat my yard if my dog is on flea and tick prevention?
Pet prevention protects the pet. It doesn’t reduce ticks in the yard, which can still bite people. Yard work and wildlife control lower the overall numbers.
When is the best time to start tick prevention in the yard?
Before spring, when nymphs become active. Fall leaf cleanup is also important, because it removes the cover ticks use through winter.
