When it comes to protecting your pets from fleas, choosing the right treatment is crucial. With a variety of options available, such as spot-on treatments, oral medications, and flea collars, it can be difficult to know which one is best for your pet. Each treatment works differently, and the effectiveness may depend on your pet’s lifestyle, health, and environment.
In this blog, we’ll explore and compare the three most popular flea treatment options: spot-on treatments, oral medications, and flea collars. This guide will help you make an informed decision for your pet, especially for pet owners in New Zealand, where the warm climate often leads to year-round flea activity.
Spot-On Flea Treatments
How They Work: Spot-on flea treatments such as Bravecto, are liquid medications applied directly to your pet’s skin, typically between the shoulder blades where they can’t lick it off. The active ingredients in the treatment are absorbed into your pet’s skin and spread across their body, killing fleas on contact. Some formulations also target flea eggs, larvae, and other pests like ticks and mites.
Effectiveness: Spot-on treatments are highly effective and provide quick relief from flea infestations. They start working within 24 hours and usually protect pets for up to 30 days. Many pet owners prefer spot-on treatments for their ease of use and fast action.
In New Zealand, where the climate favours flea growth, monthly spot-on treatments can help prevent recurring infestations. These treatments are waterproof, so pets that love to swim or roam outdoors in the rain can still be protected.
Pros:
- Easy to apply and long-lasting (usually one month of protection).
- Kills adult fleas quickly and may also target eggs and larvae.
- Waterproof formulations available, making them suitable for outdoor pets.
- Some spot-on treatments also protect against ticks and other parasites.
- Some pets may have mild reactions to the topical application, such as temporary skin irritation.
- Care must be taken to apply it correctly, as pets may try to lick the area before it dries.
- Must be applied regularly to maintain protection.
- Pets that spend a lot of time outdoors, especially in areas with high flea activity.
- Owners looking for a treatment that kills fleas quickly and is relatively easy to use.
Oral Flea Medications
How They Work: Oral flea medications come in tablet or chewable form and are ingested by your pet. Once digested, the medication enters your pet’s bloodstream. When a flea bites your pet, it ingests the blood containing the active ingredient, which kills the flea. Some oral medications kill fleas within hours of ingestion, while others also help break the flea life cycle by preventing eggs from hatching.Effectiveness: Oral flea treatments are highly effective at killing adult fleas and work quickly. Some products begin to work within 30 minutes of administration. The protection can last anywhere from 24 hours to one month, depending on the product. In New Zealand, oral medications can be a reliable option, especially during peak flea seasons when infestations can develop rapidly.
Pros:
- Fast-acting: Fleas begin dying within hours of ingestion.
- No risk of your pet licking off the treatment or washing it away.
- Available in chewable or flavored tablets, making them easy to administer.
- Some oral medications also protect against other parasites like ticks, heartworms, and intestinal worms.
- May cause mild side effects in some pets, such as upset stomach or lethargy.
- Must be given regularly, with some medications needing to be administered monthly or even more frequently.
- Does not repel fleas but kills them after they bite your pet, meaning your pet may still experience itching until the fleas are killed.
- Pets that dislike topical treatments or have skin sensitivities.
- Owners who prefer a quick and convenient method of flea control.
- Pets with a high risk of flea infestations or other parasite infections.
Flea Collars
How They Work: Flea collars are worn around your pet’s neck and release active ingredients that either repel fleas or kill them on contact. Some flea collars contain insect growth regulators (IGRs) that help prevent flea eggs from maturing into adults. The chemicals spread through your pet’s skin and fur, offering protection across their entire body.
Effectiveness: Flea collars have improved over the years and are now available in advanced formulations that provide long-lasting protection—some lasting up to eight months. They work by either killing fleas that come into contact with your pet’s fur or repelling fleas altogether.
Flea collars can be particularly beneficial for pets living in rural areas of New Zealand, where flea infestations can be more severe. However, they may not be as fast-acting as spot-on treatments or oral medications, especially in the case of an existing infestation.
Pros:
- Long-lasting protection: Some collars offer protection for up to eight months, meaning less frequent application.
- No need for monthly treatments.
- Collars are easy to use and require minimal maintenance.
- Some collars also repel other parasites like ticks.
- May take longer to kill existing fleas compared to spot-on treatments or oral medications.
- Not ideal for pets that swim frequently, as water exposure can reduce the collar’s effectiveness.
- Some pets may be irritated by the collar, especially if it’s not fitted properly.
- Limited protection for pets with heavy infestations—flea collars are often better for prevention rather than treatment of active infestations.
- Pets that prefer not to have topical or oral treatments.
- Owners looking for a long-term, low-maintenance option.
- Pets in rural or outdoor environments where consistent protection is needed over long periods.

In New Zealand, where fleas can be a year-round issue, staying on top of your pet’s flea treatments is essential. The treatment you choose should reflect your pet’s daily habits and risk level. For pets that spend a lot of time outdoors, spot-on treatments or flea collars may offer the best protection. For those who need quick relief from fleas, oral medications are a great option.
