August Parasite Prevention Check: Why Fleas, Ticks, and Heartworms Are Still a Major Texas Risk

July 13, 2026

By August, many families are thinking about school schedules, late-summer plans, and the hope of slightly cooler days ahead. But in The Woodlands, Texas, parasite season is still very active. Fleas, ticks, and mosquitoes do not take a break just because summer is winding down. Late summer can also be one of the easiest times for prevention routines to slip, especially when travel and changing schedules make monthly doses easier to forget.

At Forest Crossing Animal Hospital, we encourage owners to use August as a parasite prevention check-in. This is the time to make sure your dog or cat is current on flea, tick, and heartworm protection, especially if a dose has been missed or you are not sure when the next one is due. Consistent prevention helps protect your pet from itching, infection, heartworm disease, and preventable parasite problems.

Missed Preventives Can Create Bigger Problems Than Expected

It is easy to miss a monthly preventive. Maybe your family traveled, your pet stayed with a sitter, the reminder got dismissed, or the refill ran out before you realized it. One missed dose may not seem like a big deal, but parasites can take advantage of even a small gap in protection. In a warm, humid area like The Woodlands, exposure can happen quickly during walks, backyard play, or potty breaks.

Flea infestations can begin before owners see adult fleas. Ticks can attach after time in grass, brush, or wooded areas. Mosquitoes can bite during short outdoor moments, putting pets at risk for heartworms. Because these risks are often invisible at first, prevention has to stay ahead of the problem.

If your pet has missed a preventive dose, do not guess about what to do next. Some products have specific restart recommendations, and heartworm prevention may require testing depending on the situation. Forest Crossing Animal Hospital can help you get back on schedule safely.

Humid Weather Keeps Fleas Active in Late Summer

Fleas thrive in warm, humid conditions, which makes August high-risk in Texas. They can live in yards, shaded outdoor areas, and places where wildlife or other pets have been. Once fleas get into your home, they can be frustrating to eliminate because eggs and immature stages may hide in carpet, bedding, furniture, and flooring.

For pets, fleas are more than a nuisance. Some dogs and cats develop intense itching from even a few bites. Others may chew, scratch, lose hair, or develop red, irritated skin. Fleas can also contribute to tapeworm infections if a pet swallows an infected flea while grooming.

Watch for signs such as:

  • frequent scratching, licking, or chewing
  • small black “flea dirt” in the coat
  • hair loss, scabs, or red skin
  • sudden restlessness or discomfort
  • visible fleas on your pet or in bedding

If you notice these signs, schedule a visit before the problem spreads. Treating fleas early is much easier than dealing with a full home infestation.

Mosquito Exposure Means Heartworm Prevention Still Matters

Heartworm disease is one of the most serious parasite risks for dogs in our region, and cats can be affected as well. Mosquitoes spread heartworms, and in The Woodlands, mosquito exposure can continue for much of the year. That means heartworm prevention should not be paused in August or saved only for spring and early summer.

Heartworm disease can be concerning because pets may look healthy in the early stages. A dog may not cough, slow down, or show obvious signs until the disease has already affected the heart and lungs. For cats, heartworm disease can be difficult to diagnose and may cause serious respiratory problems. Prevention is much safer and simpler than treatment later.

August is a good time to confirm that your pet’s heartworm prevention is current and that annual testing is up to date. If your pet has missed doses, recently changed medications, or spent time away from home, let your veterinary team know. A quick conversation can help determine the safest next step.

Keeping Protection Consistent Through Busy Routines

Back-to-school season often changes the household rhythm. Morning routines become rushed, travel bags get unpacked, calendars fill up, and pet care reminders can be pushed aside. This is why August is a helpful time to reset your prevention habits.

Choose a system that fits your routine. Some families give preventives on the first day of every month. Others set phone reminders, use a calendar note, or pair medication time with a recurring household task. If your pet is difficult to medicate, ask about other options. The best prevention plan is one you can follow consistently.

Forest Crossing Animal Hospital can also help review whether your current products still match your pet’s lifestyle. A dog who hikes, visits daycare, or spends time near wooded areas may have different parasite risks than a mostly indoor cat, but both still need thoughtful protection. Prevention should be practical, clear, and based on your pet’s real life.
