Fleas and Ticks by Region: When and Where They Strike in the USA
A Year-Round Problem in Many Areas
Fleas and ticks thrive in warm, humid areas such as the Southeast and Gulf Coast, where they can be a threat nearly all year. In the Northeast and Midwest, tick activity often peaks in spring and fall, and some ticks can be active on mild winter days. Dry western regions have their own risks, including ticks in grassy foothills.
Why Prevention Matters
Ticks can carry diseases such as Lyme disease, ehrlichiosis, and anaplasmosis, and fleas can cause allergies, tapeworms, and anemia. Preventing infestations is easier and safer than treating them.
Prevention Basics
- Ask your vet about monthly preventives suited to your region.
- Check your pet after walks, especially in grass and woods.
- Keep lawns trimmed and remove leaf litter.
- Wash bedding weekly in hot water.
How to Check for Ticks
Run your hands slowly over your pet, focusing on the head, ears, neck, armpits, belly, and between toes. Use fine-tipped tweezers to grasp the tick close to the skin and pull straight out. Clean the area and save the tick in a sealed bag in case your vet wants to identify it.
Your Seasonal Parasite Prevention Plan
- Spring: confirm monthly preventives and check for early ticks.
- Summer: watch for fleas in warm, humid weather.
- Fall: tick activity often rises again in many regions.
- Winter: keep preventives going where it stays mild.
Mark your calendar with monthly reminders, and ask your vet which diseases are most common where you live.
Common Mistakes
- Stopping prevention in winter: mild days can still bring ticks.
- Using dog products on cats: some are toxic to cats.
- Burning or smothering ticks: this is unsafe.
- Treating only the pet: the home and yard matter too.
