Flea and Tick Season in Texas: Protecting Your Family and Pets

Every spring, the calls start coming in: 'My dog is covered in fleas,' 'We found a tick on our kid after playing in the yard,' 'I am getting bitten all over my ankles inside the house.' Fleas and ticks are one of the most common pest problems we treat in Rockwall County, and they hit pet owners especially hard. The good news is that a combination of pet treatment, yard management, and professional pest control can effectively control both.

When Fleas and Ticks Are Active in North Texas

In North Texas, flea and tick season runs from roughly March through November, with peak activity from May through September. Unlike states with harsh winters that freeze flea and tick populations back to near zero, our mild winters mean these pests never fully die off. A week of 40-degree nights slows them down but does not eliminate them. We have treated active flea infestations in Rockwall homes in January during warm spells.

Ticks in particular are active anytime temperatures are above 45 degrees, which means they are a concern during fall and winter hikes around Lake Ray Hubbard, on trails in Harry Myers Park, and anywhere with tall grass or wooded areas in Rockwall County.

Fleas: How Infestations Start and Spread

Most flea infestations start with a pet. Your dog or cat picks up fleas from the yard, another animal, or anywhere they are exposed to infested environments. A single flea can lay 40 to 50 eggs per day, and those eggs fall off your pet onto carpets, furniture, bedding, and anywhere the pet rests. In the right conditions — and North Texas warmth and humidity are ideal — those eggs develop into biting adults in as little as two weeks.

Here is what makes flea infestations so persistent: only about 5% of the flea population at any given time is adult fleas you can see. The other 95% is eggs, larvae, and pupae hiding in your carpet fibers, between floorboard cracks, and in upholstery. Killing the adults without addressing the eggs and larvae means a new wave of fleas will emerge in one to two weeks.

Signs of a Flea Infestation

• Your pet is scratching excessively, especially around the base of the tail, belly, and neck
• You see tiny, dark, fast-moving insects on your pet's skin when you part the fur
• Flea dirt — small black specks that look like ground pepper on your pet's skin or bedding. Place some on a wet paper towel; if it turns reddish-brown, it is digested blood and confirms fleas
• Bites on your ankles and lower legs, typically in clusters or lines
• You see small, jumping insects on carpet, furniture, or bedding

Ticks in North Texas: Species and Risks

Several tick species are common in the Rockwall area:

• Lone Star tick — The most common tick in North Texas. Aggressive biters that will actively pursue hosts. Females have a distinctive white spot on their back. Can transmit ehrlichiosis and alpha-gal syndrome (red meat allergy), which has been diagnosed in several North Texas residents in recent years
• American dog tick — Common in grassy areas and along trails. Can transmit Rocky Mountain spotted fever, though cases in Texas are rare
• Black-legged tick (deer tick) — Less common in Rockwall County but present in wooded areas and tall grass. Transmits Lyme disease. While Lyme disease is less prevalent in Texas than the Northeast, confirmed cases exist in North Texas
• Brown dog tick — Unique among ticks because it can complete its entire life cycle indoors. If your dog brings these inside, they can establish a population in your home, hiding in cracks, behind baseboards, and in dog bedding

A Three-Part Approach That Actually Works

Effective flea and tick control requires treating three areas simultaneously. If you only address one, the problem will come back:

1. Treat Your Pets

Talk to your veterinarian about a monthly flea and tick preventative for every pet in the household. Modern oral and topical preventatives are highly effective and are the foundation of flea and tick control. If one pet is treated but another is not, the untreated pet keeps the cycle going.

2. Treat Your Home

For active flea infestations inside, professional treatment targets all life stages — adults, larvae, and eggs. We use a combination of adulticide and insect growth regulator (IGR) that prevents eggs and larvae from developing into adults. Vacuuming before and after treatment is critical because it vibrates carpet fibers and triggers pupae to hatch, exposing them to treatment. You should also wash all pet bedding, throw blankets, and removable cushion covers in hot water.

3. Treat Your Yard

Fleas and ticks live in shaded, moist areas of your yard — under bushes, in ground cover, along fence lines, and in mulch beds. These are the areas your pets pick them up before bringing them inside. Professional yard treatment targets these zones with residual product that continues working between treatments. We also recommend keeping grass mowed short, removing leaf litter, and trimming bushes to reduce the shaded, humid habitat that fleas and ticks prefer.

Yard Management Tips

• Keep grass mowed to 3 inches or shorter — Ticks especially prefer tall grass where they can 'quest' (climb to the top of a blade and reach out to grab a passing host)
• Remove leaf litter and brush piles — These hold moisture and provide ideal flea and tick habitat
• Create a 3-foot gravel or wood chip barrier between your lawn and wooded or wild areas if your property borders undeveloped land
• Keep playground equipment, patios, and dog runs in sunny areas — Fleas and ticks avoid direct sunlight
• Discourage wildlife — Deer, raccoons, opossums, and feral cats all carry ticks and fleas into your yard. Secure trash cans, do not leave pet food outside, and consider fencing
