Understanding NexGard and its Effectiveness

NexGard is a chewable medication containing afoxolaner, a broad-spectrum insecticide. It's highly effective against adult fleas, killing them quickly after ingestion by your pet. However, NexGard's primary target is adult fleas, not flea eggs.

What NexGard Does Kill:

Adult fleas: NexGard is incredibly effective at eliminating adult fleas on your dog. This significantly reduces the flea population and prevents further bites.
Ticks: It also provides protection against several tick species, offering comprehensive parasite control.

What NexGard Doesn't Kill:

Flea eggs: NexGard doesn't directly kill flea eggs. The medication works by targeting the adult fleas, preventing them from laying more eggs and breaking the life cycle at that stage.
Flea larvae: Similarly, NexGard has no impact on the larval stage of the flea life cycle.

The Complete Flea Life Cycle: Why NexGard Alone Isn't Enough

Understanding the flea life cycle is crucial for effective flea control. Fleas go through four stages:

Egg: Adult fleas lay eggs on your pet, which then fall off into the environment.
Larva: Eggs hatch into larvae that feed on organic debris, including flea feces.
Pupa: Larvae spin cocoons and enter the pupa stage, developing into adult fleas.
Adult: Adult fleas emerge from the cocoons, jump onto a host (your pet), and begin feeding and reproducing.

Since NexGard targets only the adult stage, you need additional strategies to tackle eggs and larvae.

How to Eliminate Flea Eggs and Larvae

To effectively control a flea infestation, you must address all life cycle stages. Here's a multi-pronged approach:

1. Thorough Cleaning:

Vacuum frequently: Vacuum your home meticulously, paying special attention to carpets, rugs, pet bedding, and areas where your pet spends the most time. Dispose of the vacuum bag immediately afterward.
Wash bedding: Wash all pet bedding and other washable fabrics in hot water (at least 130°F) and dry on high heat to kill fleas and eggs.
Steam cleaning: Consider steam cleaning carpets and upholstery to kill fleas and their eggs.

2. Environmental Sprays and Treatments:

Insect growth regulators (IGRs): These products disrupt the flea life cycle by preventing eggs from hatching and larvae from developing. Many flea sprays and foggers contain IGRs.
Adult flea treatments for the environment: Use sprays and foggers specifically designed to kill adult fleas in your home.

3. Consult Your Veterinarian:

Your vet can recommend the best course of action for your specific situation. They might suggest other flea medications or additional treatments to complement NexGard.

Frequently Asked Questions (FAQs)

Q: How long does it take for NexGard to kill adult fleas?

A: NexGard typically begins killing adult fleas within hours of administration.

Q: Can I use NexGard with other flea treatments?

A: Always consult your veterinarian before combining NexGard with other flea treatments.

Q: My dog still has fleas after using NexGard. What should I do?

A: If your dog still has fleas after using NexGard, consult your veterinarian. There might be a reinfestation, or another underlying issue.

Conclusion

While NexGard is excellent at killing adult fleas, it won't eliminate flea eggs. For complete flea control, a comprehensive approach combining NexGard with thorough cleaning and environmental treatments is essential. Remember to consult your veterinarian for personalized advice and to ensure the safety and effectiveness of your chosen flea control strategy. Don't let flea eggs derail your efforts—take a multi-faceted approach to keep your home and pet flea-free.
