What Is Negasunt Dusting Powder 40g for Dogs?
Negasunt Dusting Powder 40g is a veterinary antiseptic and insecticidal wound powder specifically formulated for dogs. It is used to manage fly strike wounds (a condition called myiasis), open and infected skin lesions, post-surgical wounds exposed to flies, and moist or oozing skin injuries that require drying and protection.
Unlike systemic medications, Negasunt works directly at the wound surface — it kills maggots on contact, creates a hostile environment for fly eggs, controls secondary bacterial growth, and absorbs wound moisture to accelerate the drying and healing process.
When Is Negasunt Dusting Powder Used?
Veterinarians commonly recommend Negasunt Dusting Powder for the following conditions in dogs:
| Condition | Description |
| Fly Strike Wounds (Myiasis) | Fly larvae infesting open wounds — most common in summer, in outdoor and rural dogs. Negasunt kills maggots on contact and prevents re-infestation. |
| Traumatic Cuts & Abrasions | Open wounds from bites, scratches, or injuries that are at risk of fly strike or secondary bacterial infection. |
| Post-Surgical Wounds | Healing surgical sites exposed to flies, especially in outdoor dogs or during warm months. |
| Infected Moist Lesions | Chronic wet or weeping skin lesions where moisture is promoting bacterial growth. |
| Pressure Sores & Ulcers | Slow-healing ulcerated wounds in dogs with limited mobility. |
| Foul-Smelling Wounds | Negasunt helps reduce odor from infected or necrotic wound tissue during healing. |
Not for use on cats, puppies under 8 weeks, or near eyes, nose, mouth, or genitals.

Negasunt Dusting Powder — Composition
| Active Ingredient | Role |
| Coumaphos | Organophosphate insecticide — kills maggots (fly larvae) on contact and repels adult flies from the wound site |
| Propoxur | Carbamate insecticide — secondary insecticidal action, broadens the spectrum against fly species |
| Sulfanilamide | Antibacterial sulfonamide — controls secondary bacterial infection at the wound surface |
Always confirm composition with your veterinarian. Do not use alongside other organophosphate products — risk of toxicity through combined exposure.
How to Apply Negasunt Dusting Powder on Your Dog — Step-by-Step

- Put on disposable gloves before handling the product.

- If maggots are visible, remove as many as possible manually using tweezers or forceps.
- Dry the wound area thoroughly using a clean cloth or gauze.
- Hold the Negasunt bottle above the wound and dust a thin, even layer directly over the affected area.
- Do not rub the powder in — leave it sitting on the wound surface.
- Leave the wound open unless your veterinarian specifically advises bandaging.
- Place an E-collar on your dog immediately to prevent licking.
- Wash your hands thoroughly after application.

“Vet recommended it for Rex’s post-surgery wound — worked perfectly”
Rex had orthopedic surgery and the incision site kept getting irritated from the summer heat and flies getting to it despite our precautions. Our vet suggested Negasunt powder as a protective measure. We applied it lightly once a day around the site as instructed. No infection developed, the wound stayed dry throughout recovery, and Rex healed ahead of schedule according to our vet. This is a genuinely useful veterinary product that’s hard to find locally. MomasPets had it in stock and delivered to Atlanta fast. Highly recommend for anyone dealing with post-surgical wound management in dogs.

“Dealt with Duke’s fly strike wound fast — this powder is incredible”
Duke is an outdoor dog and last August he got a wound on his back leg that we didn’t notice for a couple days. By the time we found it, there were maggots. It was horrifying. Our vet prescribed Negasunt Dusting Powder immediately. We cleaned the wound, removed what we could, and dusted the powder as directed. Within 24 hours the maggots were gone. The wound stayed dry and started healing cleanly after that. We continued for 5 days total with twice daily application. Vet was genuinely impressed at the follow-up. This product works fast and works well. Ordered through MomasPets — arrived quickly and was exactly what we needed.

“Best wound powder we’ve used — no infection, healed clean”
Copper got a deep cut on his side during a hiking trip. We cleaned it up but it got moist and infected within two days despite our best efforts. Our vet recommended Negasunt powder for the infection and to keep flies away while the wound healed. We live rurally and fly strike is a real concern. Applied once daily for a week. The wound stayed dry, no maggots, no further infection, and it healed with minimal scarring. The powder is easy to apply — just dust it on gently and let it sit. I keep a bottle stocked now as part of our first aid kit for Copper.
