Botflies, from the Cuterebra genus, are a threat to dogs in North America. They’re found in the U.S., Canada, Mexico, and the neotropical region. Dogs might pick up “warbles,” the larvae, by hunting rodents or rabbits.
These larvae often show up around a dog’s head and neck but can be elsewhere too. If they break the skin, infections or abscesses might need a vet’s help. Adult Cuterebra flies have a short life, living less than two weeks, making fast action necessary.
Studies1 show the larvae’s growth varies depending on the host. In small rodents, it can take 19 to 38 days. But in jackrabbits, it might last 55 to 60 days. Botfly larvae take 7 to 11 months to mature, but it can be faster, just 28 days.
Getting warbles can cause secondary bacterial infections and skin abscesses in dogs. If a dog gets a few warbles, they usually recover well. But many warbles or if they hit vital areas, the outlook gets worse. It’s key to catch it early and get vet care fast.
Key Takeaways:
- Botflies, especially the Cuterebra genus, are common in North America.
- Dogs can pick up botfly larvae while they hunt.
- Warbles often appear around a dog’s head and neck.
- Larvae exiting the skin can cause serious health issues.
- It’s vital to get timely help from a vet.
The Life Cycle of Cuterebra or Botflies
Botflies from the Cuterebra genus start their lives by laying eggs near places where rodents and rabbits live. Soon after, the eggs hatch and tiny larvae come out. These larvae make their way into a host’s body through openings like the nose or mouth, or even cuts.
Once inside, they move to the tissue under the skin. Here, they grow and develop further.
“Twenty-six species of Cuterebra are known to occur in the U.S. and Canada.”1
Different Cuterebra fly species have their own ways of moving inside their hosts. They go to specific places in the host’s body. This helps them grow the best they can.
The time it takes for larvae to develop changes with different hosts. For small rodents, it’s between 19 to 38 days. For jackrabbits, it’s between 55 to 60 days.
“Larval development within the host may last from 19 to 38 days in small rodents and from 55 to 60 days in jackrabbits.”1
After they fully grow, the larvae leave the host and start the pupation stage. This stage can last a long time, from 7 to 11 months, or be as short as 28 days. The temperature and type of botfly affect the length of this stage.
“The pupation period for Cuterebra larvae may be as long as 7 to 11 months or as short as 28 days, depending on environmental temperature and botfly species.”1
Next, the pupae turn into adult flies. They come out of the soil or debris where they pupated. Adult botflies have a short life span, not living more than two weeks. In this time, they mate and lay eggs, starting the cycle all over again.
The cycle of Cuterebra flies shows us how well they adapt to survive. It’s important to know how they live to protect and take care of pets properly.
Symptoms of Cuterebra in Dogs
In the beginning, you might not see the infection on your dog’s skin. Soon, a swollen spot can appear, with a tiny hole visible. This hole can grow as the larvae get bigger. If not noticed early, the larva might leave the body. This can cause nasty infections or abscesses. Sometimes, the larvae travel inside the body, hurting tissues and causing pain.
Cuterebra often affects dogs around their heads and necks. Data shows1 this is where most dogs get infected. Also, small dogs under 10 pounds are more likely to get this. Yorkshire Terriers, in particular, represent 40% of these cases2.
| Common Symptoms | Severity |
|---|---|
| Swollen area beneath the skin | Varies |
| Small hole or opening | Varies |
| Enlarged swelling as larvae mature | Varies |
| Secondary bacterial infections or abscesses | Varies |
| Migrating larvae causing inflammation and damage | Varies |
It’s vital to know that if the brain or spinal cord gets infected, there’s a 30% chance the dog won’t make it, as the data tells us2.
Treatment for Botflies in Dogs
Treating botflies in dogs is all about timing. The treatment varies if the larvae are still inside the skin or have left it.
If found early, the vet removes the larvae through surgery. They make sure to get it all out. The area around the wound may be cleaned out to help healing. Antibiotics are often given to stop infections1.
If the larvae have left the skin, the wound is cleaned and tidied up. Antibiotics might still be needed to stop infections2. The vet might also suggest other treatments based on where the wound is2.
Sometimes, if the wound is bad or the tissue damage is big, surgery might be needed to close the wound. This helps in healing and stops more problems2.
After treatment, it’s key to take great care of the wound. This includes seeing the vet often. This ensures the wound heals right and avoids more issues.
Caring for the Wound
After taking out the larvae or treating the wound, keeping it clean and dry is key. The vet might suggest cleaning it with a gentle antiseptic or salt water. Using antibiotic creams as told can help stop infections and help healing.
It’s important to stop the dog from scratching or licking the wound too much. An Elizabethan collar can help prevent this. Touching the wound too much can make healing take longer and can cause more issues.
Potential Side Effects and Follow-Up Care
After treatment, some swelling, redness, and discomfort at the treatment site are normal. Yet, owners should watch for trouble signs like more swelling, more pain, bad smells, discharge, or signs of infection. These include fever, tiredness, or not wanting to eat. If you see any, talk to the vet right away.
The vet will set up follow-up visits to check on the healing. If the botfly problem was severe, more visits might be needed to make sure the dog fully recovers.
Treating botflies in dogs needs careful attention, wound care, and the right meds. With the right care and follow-ups, most dogs heal well with little chance of long-term issues1.
Prognosis for Dogs with Botflies
When dogs get botflies, how well they do can change based on a few things. If a dog has only a small number of warbles, they usually get better fully with no lasting problems. But, if there are many warbles or they’re in delicate areas, things could be worse.
- Reference:1
The number and place of warbles are key in figuring out how a dog’s health might be affected. Warbles often hit dogs in the head and neck area. This is because they run into botfly larvae near places where rodents live while they are out hunting. Being in these areas puts them at a higher risk of getting infected.

“Most cases of Cuterebra infection in dogs happen around the head and neck. This is when they come across botfly larvae near where rodents live, during their hunts.” (Source:1)
To wrap up, dogs with botflies can have a good outcome if the infection is small and not in sensitive spots. However, stopping infections from happening, finding them early, and getting vet help fast is key to keeping our pets safe and healthy.
Preventing Botflies in Dogs
Keeping your dog safe from botfly infestations is very important. You can lower the chances of your pet getting these parasites by being proactive.
Limiting your dog’s contact with animals like rodents and rabbits helps prevent botflies. By doing this, you can cut down the infestation risk. Keep your dog leashed outdoors and stop them from chasing these animals.
Checking your dog’s skin regularly helps catch early signs of botfly larvae, known as warbles. Watch out for swelling, openings, or unusual bumps. If something seems off, a vet should check your dog to stop any serious damage.
In places with many rodents or rabbits, botflies are a bigger threat. If you live in such areas, be extra careful. Using flea and tick prevention can also help protect against botflies.
Botfly infestations can cause many problems for your dog, like swollen skin and infections. They might even face neurological issues if the larvae reach important areas. That’s why preventing botflies is key to keeping your dog healthy.

What Are Cuterebra?
Cuterebra are types of North American bot flies. They lay their eggs close to rodent and rabbit homes. These eggs hatch, and the baby flies, called larvae, get inside the host to grow. They live under the skin and are known as “warbles.” While Cuterebra flies don’t bite, their larvae can make dogs, cats, and other animals sick.
Cuterebra infestations range in severity. Dogs often get them through outdoor activities like farm work or hunting. Horses, cattle, and sheep can also be affected. The larvae stick to the dog’s body through wounds or when a dog licks them up. They make their way inside, causing swellings, oozing pus, and creating a tiny breathing hole.
It’s important to get a vet to remove Cuterebra larvae to avoid bad reactions. Dogs shouldn’t lick these spots to heal better. Although not usually deadly, these infections can lead to allergies if not removed. Keeping your pets free of fleas and ticks helps prevent these issues. Regular checks and quick vet visits are key for dogs with Cuterebra to avoid serious problems4.
Causes of Cuterebra in Dogs
Dogs might get Cuterebra from accidental contact with its eggs or larvae. This can happen while they’re hunting or just being outside. The larvae enter the dog’s body through openings like wounds or the nose. Once inside, they move around inside the dog, causing swelling and sometimes, infections1.
Cuterebra flies don’t pick favorites between dogs and cats for hosting their larvae. Any dog, no matter its breed or size, can get infected if it comes in contact with these larvae2.
Common Causes and Statistics of Cuterebra Infections in Dogs
| Cause | Statistics |
|---|---|
| Accidental contact with eggs or larvae while hunting | |
| Larvae gain access through wounds, mouth, or nose | |
| Migration through the dog’s tissues | |
| Swelling, abscesses, or infections | |
| Commonly infests dogs and cats |
To keep your dog safe, knowing about Cuterebra causes is important. Tips like avoiding rodent-populated areas and checking your dog’s skin can lower infestation risks. Making these preventive steps part of your routine can help your furry friend stay away from this harmful parasite1.
