Let’s team up to outsmart those lice and get your piggy’s skin irritation under control. I’ll draw from my decades of experience to provide the best advice on restoring your guinea pig’s health and comfort. Now let’s dive in!

How Do Guinea Pigs Get Lice?

Guinea pigs can catch lice by coming into direct contact with another infested guinea pig. Lice can also spread through contaminated objects like bedding, food bowls or toys. Some ways your guinea pig may be exposed include:

  • Introduction of a new guinea pig into the home or cage
  • Playdates with infested guinea pigs
  • Boarding at a facility with an outbreak
  • Shows and exhibitions with infected guinea pigs
  • Pet store housing infested guinea pigs
  • Use of contaminated pet supplies or bedding

Lice are species-specific parasites. This means guinea pigs only get guinea pig lice – they cannot catch human lice or lice from other animals. The lice also cannot live off of humans, so you don’t need to worry about getting guinea pig lice yourself.

However, you can inadvertently transfer lice between piggies by handling them in close succession without washing your hands in between. Be mindful of good hygiene when interacting with multiple guinea pigs.

Types of Lice in Guinea Pigs

There are two main varieties of lice that afflict guinea pigs:

Sucking Lice

These lice pierce the skin and suck blood from the guinea pig. Heavy infestations can cause significant blood loss, resulting in anemia. Sucking lice are more dangerous as they can also potentially transmit blood-borne diseases between infected guinea pigs.

Chewing or Biting Lice

These lice feed on skin, secretions and debris. They do not suck blood but still cause irritation, itchiness and discomfort to the guinea pig. Generally less harmful than sucking lice but still problematic.

Knowing the type of lice is important, as treatment options can vary. Your vet can identify the specific lice under a microscope and recommend targeted medication.

Symptoms of Lice in Guinea Pigs

Lice themselves are visible to the naked eye, but they often cluster in hidden areas around the neck, ears, rump and skin folds where fur is sparse. Signs your guinea pig may have lice include:

  • Itchiness, scratching and skin irritation
  • Restlessness and discomfort
  • Inflamed skin, especially around the neck and ears
  • Scabs or hair loss from scratching
  • Anemia (pale gums) from blood-sucking lice
  • Lethargy from anemia and discomfort
  • Seeing live lice or eggs (nits) in the fur
  • Symptoms may wax and wane. Stress can trigger flare-ups and make infestations worse. Weakened, young or stressed guinea pigs tend to be more severely affected.

Checking Your Guinea Pig for Lice

To check for lice, part your guinea pig’s fur and examine the skin closely. Especially look behind the ears, around the neck and in skin folds where lice congregate. Use a magnifying glass or lice comb to help spot the tiny parasites.

What should you look for?

Adult lice:

Tiny (1-1.5mm) insects visible moving through the fur near the skin. Often light colored.

Eggs (nits): Tiny white or yellow ovals attached to hair shafts near the root.

Signs of scratching: Scabs, redness, broken hairs, balding patches.

Catching lice early allows quicker treatment, so aim to do periodic at-home checks. Also have your vet inspect for lice during wellness exams. If you think you see lice, contact your vet before treating at home.

Getting a Lice Diagnosis from Your Vet

While an initial at-home lice check is useful, always seek an official diagnosis from your exotic pet veterinarian.

Your vet will conduct a thorough physical exam, inspect your guinea pig’s skin under a microscope and may take a skin scraping to identify lice and eggs. This allows them to determine the type and extent of the infestation for proper treatment.

Do not attempt to treat guinea pig lice without a veterinary diagnosis. Well-meaning use of over-the-counter lice products meant for humans or other animals can seriously harm your guinea pig. Always consult an exotics vet first.

Safe Lice Treatment Options for Guinea Pigs

There are effective prescription medications to safely rid your guinea pig of lice. Popular topical treatments include:

  • Ivermectin – Kills lice and mites. Used as drops on the skin. Must be precisely dosed for guinea pig’s size to avoid toxicity.
  • Advantage/Advantage II – Contains imidacloprid to paralyze and kill lice. Applied topically. Use kitten-size doses for guinea pigs under 5lbs.
  • Revolution – Selamectin treatment also effective against lice. Often prescribed for guinea pigs.

Oral treatments like ivermectin in drinking water may also be recommended by your vet. Always follow your vet’s prescribed dosage and treatment schedule to ensure complete elimination of the lice.

Do NOT use flea powders, dog/cat lice shampoos, human lice treatments, or over the counter anti-parasite medications on your guinea pig without explicit veterinary approval. The improper use of these products can cause seizures, organ damage and death in guinea pigs. Work with your exotic vet for safe, effective prescription lice remedies.

Your vet may also prescribe antibiotics, anti-inflammatories or supplements if your guinea pig has any secondary skin infections or anemia stemming from severe lice infestation. Addressing these related conditions helps get your guinea pig back to full health.

Preventing Lice Re-Infestation

After treatment, take the following steps to prevent another lice outbreak:

  • Replace all old guinea pig bedding with fresh, clean bedding. Discard any old hay, toys, hides or food.
  • Wash all hard surfaces in the habitat thoroughly with pet-safe cleaner. Avoid harsh chemicals.
  • For fabric items, seal in a plastic bag and freeze for 48-72 hours to kill any lingering lice or eggs.
  • Clean yourself thoroughly after handling an infested guinea pig to avoid transferring lice.
  • Isolate and treat any other in-contact guinea pigs as advised by your vet.
  • Limit interaction with new guinea pigs during treatment period.
  • Continue periodic at-home lice checks of your guinea pigs.

With vigilance, you can break the lice life cycle and keep them from returning. But always contact your vet at the first signs of re-infestation for follow-up care. Recurrent lice may require an additional round of medication.

Cleaning Your Guinea Pig’s Environment

Regular cage cleaning and habitat hygiene helps prevent and control lice outbreaks:

  • Spot clean droppings daily. Remove uneaten hay and food.
  • Every 1-2 weeks, dump all old bedding and fully disinfect the habitat.
  • Wash food bowls, bottles, hides and toys weekly.
  • Change out fabric liners and hammocks weekly for washing.
  • Use paper-based, absorbent beddings instead of fabric liners if lice are an issue.
  • Freeze new wooden chews and hay for 24 hours before use to kill pests.
  • Quarantine new guinea pigs before introducing them to your group.
  • Isolate and treat infested guinea pigs away from the main habitat.
  • Follow basic hygiene like washing hands before and after handling each piggy.

Proper cleaning helps eliminate places for lice to hide and thrive in the environment. For best results, maintain strict cage hygiene along with lice treatment.
