What are botflies?
Have you ever noticed a strange lump on your dog’s skin and wondered what on earth could be causing it? It could be something you’ve never thought of: botflies.
These sneaky pests, scientifically called Cuterebra, use animals, including our beloved pups, as unwitting hosts for their larvae. Gross, right?
This parasitic condition can definitely be a dangerous one if left untreated. But don’t worry. While it sounds unsettling, a botfly infestation is manageable with the right care.
In this guide, we’ll break down everything you need to know about botflies in dogs – from spotting the symptoms to getting rid of them and ensuring your dog recovers fully.
Whether you’re just curious or dealing with a potential infestation in your furry friend, we’re here to help.

Symptoms of botflies in dogs
When it comes to spotting a botfly in dogs, one of the most obvious signs is a lump under the skin, often with a small hole. That hole? It’s the larva’s breathing tube. Yep, you read that right.
Other signs your dog might be dealing with a botfly include:
- A swelling or lump that seems out of place
- Your dog obsessively licking or scratching at a specific area
- Redness or irritation around the lump
- Skin abscess
- Signs of pain when you touch the spot
- Fever, fatigue, or a lack of appetite in more serious cases
Rare neurological symptoms
In rare cases, botfly larvae (also called “warbles”) may migrate to areas like the brain, causing severe neurological symptoms.
If your dog displays unusual behaviors such as seizures, head tilting, or confusion, seek immediate veterinary attention. These cases are uncommon, but can be life-threatening without immediate treatment.
Causes of Botfly in Dogs
How do dogs get botflies?
So, how do dogs get botflies in the first place? It’s all part of the botfly’s sneaky lifecycle.
These pests lay their eggs near rabbits or rodent burrows, or even on plants. When a curious dog sniffs around or brushes against these spots, the eggs transfer onto their fur. Once they hatch, the larvae burrow under the skin to grow.
Dogs that love to explore the outdoors, especially in wooded or grassy areas, are at higher risk. Botflies are most active during the warmer months, so summer adventures can sometimes come with unwanted hitchhikers.
Lifecycle of botflies: from egg to larva
Understanding the botfly lifecycle can help pet owners recognize risks. The lifecycle goes like this:
- Adult botflies lay eggs near rodent burrows or on plants.
- Eggs hatch into larvae upon contact with a warm host, like a dog.
- The larvae burrow into the host’s skin, forming a cyst where they develop.
- Once fully grown, the larva exits the skin and continues its lifecycle in the soil.

Diagnosis of botflies in dogs
Diagnosing a botfly in dogs is pretty straightforward for a vet. They’ll check the lump and look for that telltale breathing hole. Depending on the situation, the vet might also recommend:
- X-rays or CT scans to rule out deeper infestations or complications.
- Lab tests to ensure it’s not another type of infection.
The faster you get a diagnosis, the better, since early treatment helps avoid more serious issues.
Treatment of Botfly in Dogs
When it comes to treating a botfly on a dog, it’s absolutely crucial to let a vet handle it. Why? Because trying to remove the larva yourself can be risky. If it bursts, it could lead to a serious infection.
Here’s how vets typically handle the process:
- Sedation or local anesthesia: To keep your dog calm and comfortable.
- Careful larva extraction: The vet will widen the breathing hole slightly and gently remove the larva using special tools.
- Wound cleaning: To prevent infection and promote healing.
- Medications: Antibiotics or anti-inflammatory drugs might be prescribed to ensure the wound stays clean and infection-free.
In rare cases, if the infestation is internal, surgery may be needed to remove the larvae.
Complications to watch out for
While most dogs recover quickly, it’s important to keep an eye out for complications like infections, abscesses, or scarring. If the wound becomes red, swollen, or starts oozing, it’s time to call your vet.

Recovery of Botfly in Dogs
Once the larva is out, your dog’s recovery is usually smooth sailing! Here’s how to help them heal:
- Clean the wound as directed by your vet.
- Keep your dog from licking or scratching at the area (a cone/e-collar might be your best friend here).
- Give any prescribed meds on schedule, even if your dog seems back to normal.
Preventing future infestations
Prevention is definitely better than treatment when it comes to botfly maggots in dogs. Here’s how to keep your pup safe:
- Avoid letting your dog roam near rabbit and rodent burrows or wooded areas, especially during peak botfly season.
- Check your dog’s fur and skin regularly, especially after outdoor adventures.
- Use vet-approved insect repellents to ward off pests.
- Limit outdoor time in areas known for botflies during warmer months.

Thank you for your question. Skin irritation in puppies is most frequently caused by parasites, fleas or Demodex. It can also be due to a bacterial or fungal infections. Since there are many reasons for this possible cause, it would be best to have your puppy seen by a veterinarian, as they can examine your puppy and see what might be causing this. I hope that all goes well.

Thank you for your question. I apologize for the delay, this venue is not set up for urgent emails.
our concern is unlikely to happen. The botfly will be digested in his stomach. If they are having problems, It would be best to have your pet seen by a veterinarian, as they can examine them, see what might be going on, and get any testing or treatment taken care of that might be needed.

If you have found wounds in her skin, it would be best to have her seen by a veterinarian, as she may need antibiotic therapy or other medications. They will be able to see what is causing this and get treatment for her so that she is healthy again.
I hope that all goes well for her.

My pet has the following symptoms:
Wound
Male, noticed he was constantly biting his side. When I looked at his side it was swollen and a hole in the middle. I put on a latex gloves, put peroxide on area and started squeezing area. No blood a little clear pus. Squeezed harder then started to notice something solid coming out. Continued to squeeze until what looks like a maggot came out. Cleaned wound with peroxide and applied neosporin. Dog is not biting area anymore, will check tomorrow and see if swelling goes down and check if there is any healing, unless you provide additional advice

Thank you for your question.
The wound from the maggot may need antibiotics if it is getting infected, and it would be best to watch the area closely for any signs of discharge, redness, or swelling. If those happen, it would be best to have your dog seen by a veterinarian, as those maggots can cause quite a bit of tissue trauma.
I hope that he is okay.

Hi... I just noticed my dog has what may look like a botfly exit wound on her hip. It may not be that but I am hoping someone can give me some advice since today is Friday and there are no vets open around me on the weekends. I will attach an image below.

Thank you for your question.
I was not able to see the image If you see a wound on your dog, the best you can do until you can have her seen by a veterinarian is to keep it clean with a solution of chlorhexidine. You can wash the area twice a day, gently. If that does not help, and the wound is still there when your veterinarian opens after the weekend, it would be best to have her seen by a veterinarian as soon as possible. I hope that all goes well.

My pet has the following symptoms:
Hole On Side
I rescued this dog from my brother’s house because we knew if we didnt come and get her and the other puppy things wouldn’t end well for them. They were kept outside, barely fed and practically fending for themselves. The dogs my brother has have puppies at least twice a year. This is the second litter their dog has had this year and I noticed a bump on her back a while ago but didn’t really mind it. I thought it was just a flea bite she had been scratching at or her brother had bitten her too hard. Well 2 weeks later i see that its open and there’s something inside. I ask my boyfriend to look at it and he said in shock that something was moving. We took a look at it and googled it. We don’t really have the money for a vet. Is there anything we can do at home to get rid of it?

My pet has the following symptoms:
Itching
I live in Colorado. Lots of rabbits here. Po loves to be outside in the grass, as well as eat rabbit poop as most dogs do. Sometimes he eats flowers and, as a result, has ingested botfly larvae in the past. While I have stopped him from eating the flowers since then, he has been exhibiting some of the symptoms he did when he had the flies before. I check him regularly for lumps, etc... but have found nothing yet. Last time the ER vet told me that if he swallows the larvae they will make their way to the surface if they can and will emerge at whatever surface they can find. As nothing has popped up yet (at least that I can find), is there something I can give him to kill anything inside that hasn't made it's way out yet?
