What's the flea and tick risk on my property?

Property flea and tick risk depends on the animal you're protecting, your region, and your property type. Answer three quick questions and we'll build your property risk profile and match the right protection plan.

What is the flea life cycle and how does it affect treatment?

The flea life cycle has four stages — egg, larva, pupa, and adult. Only the adult stage lives on the pet. The other three live in your environment: carpet, barn bedding, and cracks. A single female flea lays up to 50 eggs per day. The pupa stage can survive dormant for 6 months. This is why skipping a monthly dose can trigger a new infestation — and why consistent 30-day protection is the vet standard.

Stage 01 — The Egg

A single female flea lays up to 50 eggs per day. Those eggs fall off your pet and land in carpet, bedding, and cracks — wherever your pet rests. They hatch in 1–10 days depending on temperature.

Duration: 1–10 days Location: Off the pet

Stage 02 — The Larva

Larvae hatch and hide from light — deep in carpet fibers, barn bedding, under furniture, along baseboards. They feed on flea dirt and dander. This stage lasts 5–11 days and is when most environmental treatments miss them.

Duration: 5–11 days Location: Environment

Stage 03 — The Pupa

The most resilient stage. A pupa spins a cocoon that resists most insecticides and can lay dormant for up to 6 months — until it senses warmth, vibration, or carbon dioxide from a nearby host. This is why skipping a month can trigger a new infestation.

Duration: 5 days – 6 months Location: Deep environment

Stage 04 — The Adult

The adult flea jumps onto your pet, feeds within minutes, and starts laying eggs within 24–48 hours. This is the stage your monthly treatment kills — but if a new generation hatched while you were between doses, the cycle starts again.

Duration: 1–2 weeks on host Location: On the pet

When is flea and tick season?

Peak flea and tick season runs March through October across most of the United States. But ticks stay active any day above 40°F, and indoor fleas breed year-round. Year-round prevention is the safest approach for rural properties. Tap any month below to see what's active when.

Low Moderate Elevated High Peak

March–October is peak flea and tick season across most of the U.S. But indoor fleas breed year-round — which is why vets recommend continuing prevention through winter.

    What questions do farm families ask about flea and tick prevention?

    Farm and ranch families ask about year-round protection, product differences, safety for working dogs, species-specific products, yard and barn treatment, and livestock coverage. Real questions, structured answers, reviewed by a licensed pharmacist.

    Yes. Ticks stay active in mild winters and fleas can survive indoors year-round. On a farm or ranch, the property itself — barn, kennel, pasture edges, and outbuildings — harbors fleas and ticks year-round. Year-round protection is the vet standard for rural properties.

    Some products handle both fleas and ticks. NexGard, Bravecto, Simparica Trio, and Revolution Plus all handle both. If you're on a monthly flea-only product, you may need to add a tick preventive, especially in high-risk regions.

    Yes. NexGard, Bravecto, and Simparica Trio are all approved for working dogs and farm dogs. They're safe for dogs that spend time outdoors, in water, and on the property. Follow the weight-based dosing on the package.

    Never. Some flea and tick products labeled for dogs are toxic to cats. Always use species-specific products. For horses, use equine-labeled sprays and pour-ons. If you're unsure, ask our pharmacist at 1-800-738-6337.

    Yard treatment is critical on rural properties. Granules, sprays, and professional treatments break the flea life cycle where it starts. Treat the kennel, the barn, and the pasture edges — anywhere your animals spend time.

    Yes. Cattle, horses, goats, and sheep all benefit from fly and tick control. Pour-on formulas for cattle, equine sprays for horses, and species-specific products for smaller livestock are the standard. Ask our pharmacist for a herd plan.
