When a Small Wound Becomes a Big Problem

Understanding Maggots (Bot Fly Larvae) and Proper Wound Care

Maggots are often misunderstood—and unfairly associated with neglect. In reality, maggot infestations can happen very quickly, even in well-cared-for pets and livestock. In warm, humid environments, all it takes is a small wound and a short window of time.

Understanding what maggots are, why they’re dangerous, and how to respond correctly can prevent serious pain, tissue damage, and infection.

What Are Maggots?

Maggots are the larval stage of flies. While many fly larvae feed on dead or decaying tissue, the type of maggots that pose the greatest risk in animals come from bot flies.

This distinction is important—because bot fly larvae behave very differently.

Why Bot Fly Larvae Are So Dangerous

Bot flies are attracted to:

• Open cuts or wounds

• Moist or matted fur

• Skin folds

• Areas around the ears, tail, or underside

Once a fly lays its eggs on the skin or nearby hair, those eggs can hatch within 12–24 hours.

Unlike other maggots, bot fly larvae feed on living tissue. As they burrow into the skin, they can cause:

• Rapid destruction of healthy tissue

• Severe pain and irritation

• Inflammation and infection

• Deep tissue damage if left untreated

What starts as a small, manageable wound can quickly become a medical emergency.

Warning Signs You Should Never Ignore

Maggot infestations progress fast. Early signs may include:

• A strong or foul odor from a wound

• Swelling, redness, or discharge

• Persistent licking, biting, or scratching at one area

• Visible movement in or around the wound

• Sudden lethargy or signs of discomfort

If you notice any of these signs, immediate attention is critical.

What NOT To Do: Common Mistakes That Worsen Wounds

Not all treatments are safe—and some can cause serious harm.

Avoid using:

• Hydrogen peroxide

• Alcohol

• Harsh disinfectants

• Household chemicals

• Home remedies not recommended by a veterinarian

These substances can:

• Burn damaged skin

• Delay healing

• Increase inflammation

• Force larvae deeper into tissue

Well-intentioned treatment can unintentionally make the injury worse.

What To Do Instead: Safe and Effective Wound Care

Proper care can prevent complications and speed recovery.

Recommended steps include:

1. Clean wounds early using a gentle solution such as diluted Savlon/salve or sterile saline.

2. Do not attempt aggressive removal of maggots without guidance—improper removal can cause further damage.

3. Use veterinarian-prescribed anti-maggot medication designed to safely eliminate larvae.

4. Seek veterinary attention immediately if maggots are suspected or visible.

Prompt, professional treatment protects both the wound and the surrounding healthy tissue.

Why Early Treatment Makes All the Difference

Early wound care helps to:

• Save healthy skin and muscle

• Prevent secondary infections

• Reduce pain and discomfort

• Shorten recovery time

• Protect overall health and wellbeing

Maggot infestations move quickly—but when caught early, outcomes are often very positive.

The Takeaway

Maggots are not a sign of poor care—they are a biological risk that thrives in warm climates and takes advantage of even minor injuries. The key is vigilance, early action, and proper veterinary treatment.

If a wound doesn’t look right, smells unusual, or seems to worsen rapidly, don’t wait. Early intervention can make the difference between a simple treatment and a serious complication.
