Can Guinea Pigs Get Fleas? (What You Need To Know)
Your guinea pigs are scratching excessively. You know it’s not mites, ringworm, or lice. Is it possible? Does your guinea pig have fleas? Can guinea pigs even get fleas?
Generally, it’s rare for guinea pigs to have a full-blown flea infestation, but it’s possible if a house is completely infested. Guinea pigs don’t make good hosts for fleas, so fleas tend to move on to a better host (e.g. ferret, dogs, cats) when possible. That said, fleas will feed off your guinea pig if they can’t find a better host.

There are many treatment options available for piggies with flea infestations. We’ll go over some of them below to help you decide how best to deal with this problem and how to prevent future infestations from occurring.
Can Guinea Pigs Get Fleas? (Understand How Fleas Function)

Fleas are insects can jump as high as 13 inches in one leap and are very light (around 0.03 ounces). Fleas are insects that live off of the blood from pretty much any mammal. That said, it’s uncommon for cavies to get flea infestations.
What’s the secret?
Simple. Guinea pigs are rarely the first choice as host for fleas.
Fleas require blood from a particular host to breed successfully, so they typically won’t stay on your little friends for long. (Lucky for you and your piggies!) They need to find a host that increases their chances of survival and reproduction.
Flea infestations in cavies can often take place when your entire home is teeming with fleas – which is also uncommon.
In this case, fleas can find the perfect host in other household pets like cats, ferrets, and dogs. Now even fleas want to live. So, in desperation, some fleas will feed off humans in addition to their usual hosts. That’s how you fur babies end up covered in flea bites.
The infestation can be nipped in the bud if the home is properly treated (e.g. pesticides, cleaning, flea treatment for appropriate pets) to get rid of them before they reproduce too much.
Seeing one or two fleas on your piggie isn’t a major reason to panic – unless you live in South America. That’s the only place where fleas have been found to use cavies as a breeding host.

The good news is that fleas don’t tend to like guinea pigs as hosts. They’re not as appealing as dogs, cats, and ferrets. But, fleas will happily feed off guinea pigs if they have no other options. In that case, flea treatment is crucial to getting rid of them before they breed and create havoc in your guinea pig’s home (or yours).

How Do I know If My Guinea Pig Has Fleas?
There are a few signs to watch for if you think your guinea pig has fleas:
- excessive scratching and “picking” of fur
- unexplained balding, hair loss, or thinning fur on your piggies
- red inflamed skin
- extreme irritability or loss of appetite
- round, dark dirt specks in your guinea pig’s fur could be an indication that your cavies are infested with fleas; this only works if your pet has light-colored fur
Those dark dirty flecks are called “flea dirt”, which are flea droppings. The “flea dirt” is dirt is dried blood.
If suspect a flea infestation on your guinea pig, use this tactic to identity them. First off, if you rub some flea dirt onto a wet cloth (maybe a cotton ball or pad) it will turn red – because it’s dried blood. If you see that, then you know there’s a flea problem that you’ll have to deal with.

If you do see live fleas on your piggies, then you’re dealing with a huge infestation and need to start treatments quickly.
How Do Guinea Pigs Get Fleas?

With so many factors to consider such as your guinea pig’s living environment, it can be tricky to figure out how the fleas got on it. But, here are a few possible culprits you’ll want to keep an eye out for:
- Your guinea pig’s pet friends. It’s possible that your guinea pigs picked up fleas off of a doggie or feline – or even a ferret. It’s a risk that cavies share with their other furry friends.
- Anything your guinea pig has been rolling (or walking) in . Whether it’s a pile of leaves or just the dirt from the backyard, cavies have a way of making themselves at home when they feel comfortable and safe. Anything they’ve rolled around on is now fair game for fleas to jump onto.
- Other people. Once again, severe flea infestations in humans are rare. But, fleas can jump. There’s nothing to stop them from hitching a ride on a shirt sleeve or pants cuff and then jumping onto your guinea pig. Or they might contract the pests from infected animals and then hand it off to their fur babies at home.
During weekly health checks, make sure to look for fleas. If you see any, there are several treatments that can get rid of the pests – and protect your guinea pig from future infestations.

Avoid having carpeting in the room where your guinea pigs live, if possible. Fleas can jump from one pet to another, and a carpet likely on the floor of their home may be prime real estate for them to live when they’re not riding around with other pets or people.

Scrub away any obvious areas of dirt, grime, or flea residue. Spray a mixture of 1/2 vinegar and 1/2 water and wipe everything down.
- Keep outdoor piggies inside for a bit. If your fur babies live outside, keep them inside for a few days while you clean their habitat. If their hutch it wooden, consider painting it to decrease the amount of fleas.

Then chuck the contents in an outside trash can. (Also, best done on a day when your trash is collected.)
- Flea-Hating Plants: Certain plants contain specific substances that fleas despise, and they will try their best to avoid such plants. Just make sure that your piggies can’t get to them. Penny Royal, lavender, and spearmint can be be used inside and outside your house to repel these pests.

Can Guinea Pigs Die From Fleas?
Generally speaking, fleas themselves won’t kill guinea pigs. But, secondary illnesses caused by the infestation will. For example:
- Anemia Risk. Anemia is a blood condition that happens when cavies don’t have enough red blood cells, and this can lead to death. However, your cavies are small animals with much less blood volume than a cat or dog. If your guinea pig has a heavy flea infestation, it’s possible for them to become anemic through blood loss, which can be dangerous.
- Self-Inflicted Injuries. Cavies have a habit of severely biting and scratching themselves in an attempt to rid themselves of fleas. It can become so extreme that your piggies will give themselves open wounds. This can lead to skin infections if left untreated.
So, if a true infestation has taken over your fur babies, there’s no need to freak out. But, you’ll want to take care of it quickly.

- Mites: These are tiny bugs that live in guinea pig fur. They cause intense itching and can make guinea pigs feel really miserable. Mites can be fatal if left untreated.
- Food sensitivities: A guinea pig’s diet is the most important thing, so changing food types or brands might be all it needs to stop scratching! Always keep
- Contact dermatitis: This is a reaction from contact with an irritant, such as soap, detergent, fabric softener or other chemicals. If you’ve recently changed brands of laundry detergent and your guinea pig starts scratching more than
- Lice: These are parasitic bugs that causes itchy skin
- Certain Oils: It’s common for some cavies to be allergic to coconut oil. If you choose to use this oil on your piggie, do a patch test first to make sure it’s safe!
- Ringworm: This fungal infection can cause guinea pigs to itch. It also causes hair loss and irritated skin.
If you don’t see any signs of this pest, the best treatment option is to figure out what the root cause of all that scratching might be. The last thing you want if for your little friends to be miserable!
