Do I need year-round flea and tick prevention?

Yes. Fleas and ticks can survive indoors and in milder climates year round. Continuous prevention helps stop infestations before they start.

Can I use the same flea treatment for cats and dogs?

No. Use only products labeled for the species. Some dog treatments are dangerous for cats.

How often should I replace a flea collar?

Follow the product instructions. Many modern collars, like Seresto, protect for up to eight months.

Understand how fleas and ticks work • Updated for 2026

Fleas and ticks can cause itching, skin infections and even transmit diseases to your pets and family. Choosing the right prevention and treatment depends on your pet’s species, weight, health status and your environment.

Types of flea & tick treatments

Collars: Long‑lasting collars (like Seresto) release active ingredients slowly over months and are ideal when you want continuous protection without monthly application.

Topical treatments: Monthly spot‑on liquids applied to the skin. They’re convenient and widely used, but always match the weight range and species.

Oral medications: Prescription or over‑the‑counter tablets can provide systemic protection; some act quickly to kill adult fleas before they lay eggs.

Shampoos: Provide immediate relief by killing fleas on contact; they’re often used at the beginning of an infestation before switching to a longer‑term option.

Final tips

Always consult your veterinarian before starting a new flea or tick product, especially for young, old, pregnant or sick pets. Clean bedding and vacuum carpets, sofas and corners regularly to remove eggs and larvae. Prevention is easier than treatment — keep your pets protected year round.
