One of the most common questions pet owners ask is: how often should I treat my pet for fleas? Although many people think flea treatment is seasonal, the truth is that fleas can survive indoors year-round — especially in warm homes with central heating. This makes consistent monthly protection essential, no matter the time of year.

How Often Should I Treat My Pet for Fleas — The General Rule

Most vet-approved topical and oral flea treatments — including FLEA GUARD™ — are designed to last 30 days.

That means your pet should be treated:

✔ Once every month✔ Without gaps or delays✔ All year long

Even missing one monthly dose can allow new fleas to hatch, jump onto your pet, and restart the entire infestation cycle.

Why Staying on Schedule Matters

Fleas reproduce quickly.

A single female can lay up to 50 eggs per day, and many of those eggs fall into:

carpets
bedding
sofas
rugs

If you apply treatment irregularly, these eggs continue maturing into larvae and pupae — hidden throughout your home. By the time you see fleas again, the infestation is often well established.

This is why understanding how often should I treat my pet for fleas is critical: consistency breaks the life cycle before fleas spread.

When Treatment Frequency May Change

In most cases, monthly treatment is ideal, but certain situations require special consideration:

Puppies and kittens: Only use flea treatment once they reach 8 weeks of age (always check the label).
Senior or sensitive pets: May need gentler formulas or vet guidance.
Outdoor pets: Require strict monthly protection due to higher exposure.
Multi-pet households: Every animal must be treated to prevent reinfection.

Flea Season Never Truly Ends Indoors

Even in winter, fleas thrive in warm indoor spaces. Central heating creates the perfect environment for eggs and larvae to survive. This is why vets recommend monthly treatment throughout the entire year.
