What Insects Do Rabbits Eat (Worms, Spiders, Crickets, Ants, or Flies)?

For pet rabbits, the world is full of tasty temptations just waiting to be sampled. When a curious critter spots a crunchy cricket hopping through their habitat or a juicy beetle crawling across the carpet, their natural foraging instincts kick in! While rabbits primarily munch on hay, leaves, and vegetables, they are also hardwired to relish the occasional insect snack. Would resourceful rabbits go so far as gobbling up pesky flies or feasting on fleshy spiders? Can indulging these primal tastes ever go too far? Get ready to hop down the rabbit hole and discover the risks and rewards of rabbits eating insects! This critter craving is sure to fascinate rabbit lovers.

Do Rabbits Eat Insects?

Rabbits are herbivores, meaning their diet consists primarily of plant materials like grasses, leafy greens, vegetables, fruits, and hay. However, rabbits are opportunistic eaters and will sometimes consume small amounts of protein in the form of insects or other small animals. While insects don't make up a significant part of a domestic rabbit's diet, they may eat certain insects as a supplemental source of nutrients.

In the wild, rabbits will eat more insects than domestic rabbits due to limited access to other foods. Wild rabbits have been observed consuming various insects like crickets, caterpillars, beetles, and grasshoppers. These high-protein foods can provide important vitamins, minerals, fats, and amino acids that support a rabbit's health. Consuming insects may also provide trace nutrients not found in plants.

During spring and summer when insects are abundant, wild rabbits may eat more bugs to take advantage of the seasonal nutrients. This extra protein can help female rabbits support reproduction and nursing of young kits. For domestic rabbits, the occasional insect provides enhanced nutrition but does not need to be a dietary staple.

Rabbit owners don't need to purposefully feed insects to pet rabbits. A balanced commercial rabbit diet contains all the protein and nutrients needed for good health. However, there is usually no harm in rabbits eating the occasional insect they find in their environment. Some rabbits seem to enjoy chasing and consuming an insect snack. As long as insects are consumed in small amounts, they can be a beneficial supplement to a rabbit's diet.

What Kinds of Insects Do Rabbits Eat?

Rabbits are not prolific insectivores but will eat some bugs opportunistically. Grasshoppers, crickets, beetles, caterpillars, and winged ants are insects most commonly consumed by rabbits. These insects provide a good source of protein, fat, vitamins, and minerals. Rabbits likely developed a taste for certain insects that shared their environment. Some of the insects rabbits are known to eat include:

  • Crickets: Crickets are a favorite insect prey of rabbits. Rabbits seem to enjoy the taste and crunchy texture of crickets. Crickets provide protein, fiber, calcium, and B vitamins.

  • Grasshoppers: Like crickets, grasshoppers are another insect rabbits actively seek out and consume. Grasshoppers are a great source of nutrition.

  • Caterpillars: Fuzzy caterpillars provide an appetizing snack for rabbits. Rabbits have been observed nibbling on caterpillars in vegetation.

  • Beetles: Crunchy beetles are full of protein, healthy fat, and nutrients attractive to rabbits.

  • Ants: Rabbits will eat ants they encounter, though ants do not seem to be a preferred insect prey. Ants contain protein and acids that can support health.

  • Butterflies & Moths: Rabbits are known to chase and eat butterflies and moths if they can capture them. These insects are a good source of trace minerals.

  • Spiders: Spiders are high in protein and fat. Some rabbits appear to enjoy eating spiders they find in the environment.

  • Fly Larvae: Rabbit may eat maggots or other fly larvae they come across while grazing. These provide protein and nutrients.

In the wild, rabbits may eat other insects like mosquitos, aphids, termites, potato bugs, June bugs, and more depending on availability. The diversity of insects in a rabbit's environment impacts what kinds they consume. Overall, rabbits enjoy eating crunchy, protein-rich insects that complement their herbivorous diet.

Are Rabbits Allowed to Eat Bugs?

There is no dietary rule that rabbits cannot eat insects. In fact, wild rabbits routinely consume crunchy, protein-rich insects as part of their natural foraging behavior. Domestic rabbits do not need insects to thrive, but small amounts of bugs are allowed as an occasional treat or supplemental food source. Some insect snacks can provide beneficial nutrients to pet rabbits.

Most pet rabbit owners don't intentionally include insects in their rabbit's diet. However, allowing a domestic rabbit to eat the occasional insect they find indoors or in the yard is generally fine. Insects like crickets, grasshoppers, beetles and caterpillars are all acceptable for a pet rabbit to eat in moderation. These small amounts of supplemental protein do not harm rabbits.

There are some precautions to take around allowing rabbits to eat insects:

  • Only wild-caught insects should be allowed. Insects from bait shops may carry parasites.

  • Do not allow rabbits to overindulge on insects as too much protein can cause digestive upset.

  • Avoid insects that carry toxins like some brightly colored caterpillars.

  • Do not allow rabbits to eat stinging insects like bees, wasps or ants that may injure their mouth and throat.

With proper supervision and moderation, letting a pet rabbit nibble on a wild insect can provide enrichment and supplemental nutrition. While not all owners choose to offer insects, they can be considered an acceptable part of a rabbit's diet. Use common sense to ensure any bugs eaten are safe and healthy for your pet.

My Rabbit Keeps Eating Bugs

It's not unusual for pet rabbits to eat the occasional insect they encounter in or around the home. However, a rabbit that seems fixated on eating bugs may be trying to fulfill a dietary need. Here are some reasons why your rabbit may be seeking out insects and how to manage the behavior:

  • Boredom: Some rabbits eat insects out of boredom or curiosity. Make sure your rabbit has enough mental stimulation and playtime each day. Rotate toys to keep them interested.

  • Lacking Hay: Hay should make up the bulk of a rabbit's diet. If fed insufficient hay, a rabbit may eat insects to supplement fiber intake. Ensure unlimited access to fresh timothy or other grass hays.

  • Inadequate Pellets/Veggies: An improper balance of pellets and veggies could lead to a rabbit eating bugs to meet protein needs. Follow your vet's advice for appropriate portions.

  • Nutritional Deficiency: A nutrient deficiency could drive a rabbit to eat more insects. Have your vet evaluate your rabbit's diet and health to rule this out.

  • Natural Foraging Instincts: Wild rabbits eat more insects than pets. The inclination to forage for bugs is natural rabbit behavior. Allowing supervised insect snacking may satisfy this instinct.

  • Enrichment: Catching and eating insects provides rewarding mental stimulation. Ensure your rabbit's environment offers enough enrichment activities.

  • Attention-Seeking: Eating insects may be an attempt to get owner's attention. Spend fun daily time with your rabbit so they don't need to resort to misbehaving.

If your rabbit is fixated on eating bugs, assess their diet, enrichment, and health first. If all needs are met, allowing moderate insect consumption may be appropriate to satisfy natural drives. Monitor to ensure they don't overindulge. Discourage eating insects that could be toxic or hazardous.

How to Stop a Rabbit Eating Insects

While the occasional insect will not harm a rabbit, you may want to discourage a rabbit that tries eating bugs too frequently. Here are some tips to stop insect eating:

  • Remove Temptations: Eliminate attractive insects from the rabbit's environment. Clean up fallen fruit that attracts flies and ants. Use insect barriers on the hutch outside. Place mesh screens on windows and doorways. Keep the grass short and free of tempting caterpillars.

  • Increase Enrichment: Bored rabbits are more likely to seek out insect snacks. Make sure your rabbit has enough mental stimulation. Provide puzzle feeders, dig boxes, tunnels, chew toys, and opportunities to run and play daily. Rotate toys to keep things interesting.

  • Adjust Diet: Evaluate the amount and quality of hay, pellets, and veggies you feed. Consult your vet if you suspect nutritional deficiencies are driving insect consumption. Make sure fresh water is always available.

  • Monitor Outdoor Time: Supervise outdoor play time to intervene if your rabbit tries eating an insect. Try using a rabbit harness and leash to keep them from hunting bugs in the grass. Limit unsupervised backyard time.

  • Use Repellents: Apply natural insect repellents around your rabbit's living areas. Products containing citronella, peppermint, eucalyptus or cinnamon oils can help deter insects. Reapply after rain or as directed on the product.

  • Provide Alternatives: Give acceptable, healthy treats like hay cubes, twigs, or rabbit chew sticks to distract from insects.

  • Train "No": Discourage the behavior by saying "no" whenever you catch your rabbit eating bugs. Reward them with a treat when they stop. Be consistent.

With diligence removing temptations, enhancing their environment, and training, you can curb your rabbit's enthusiasm for insect snacks. Make sure their dietary and enrichment needs are fully met.

Would a Rabbit Eat Fleas or Ticks?

It is possible a rabbit might eat a flea or tick if the insect ended up on their body. Rabbits are known to groom themselves by licking their fur, much like cats do. During this self-grooming, they could inadvertently ingest fleas, ticks, or other external parasites. However, rabbits do not intentionally seek out fleas and ticks as a food source.

Eating a flea or tick would be an accidental consequence of a rabbit's grooming instincts, not an intentional dietary choice. Consuming a flea would likely provide minimal nutritional value to a rabbit. Ticks have the potential to transmit infectious diseases to rabbits, so eating them would be quite harmful. For these reasons, no rabbit owner would want to purposely feed fleas, ticks, or other parasitic insects to a pet rabbit.

The best way to protect a pet rabbit from ingesting fleas, ticks, or other parasites is through preventative care. This includes:

  • Daily inspection of your rabbit's coat to look for parasites

  • Treating your home and yard to eliminate fleas

  • Using veterinarian recommended flea/tick control products for rabbits

  • Keeping wild rabbits and other animals out of your yard to reduce ticks

  • Grooming your rabbit frequently to remove external parasites

While an occasional flea or tick may still make its way onto your pet, these steps will reduce the chances your rabbit could eat one during grooming. Monitoring your rabbit's health and being vigilant about parasites is key to keeping your bunny safe.

My Rabbit Chases Flies and Moths

It's common for pet rabbits to become alert and excited when an insect like a fly or moth enters their environment. A rabbit may run, jump, or chase after the moving insect. This is normal behavior triggered by their prey drive. In the wild, rabbits use quick reflexes to capture nourishing insects and bugs to supplement their diet. The tendency to react to flying insects is instinctual.

Chasing after a fly or moth provides enriching mental stimulation for a bored house rabbit. They are evolutionarily adapted to seek out these moving objects and try to catch them. You may find your rabbit staring intently at the wall or ceiling tracking the path of a fly. Some rabbits delight in leaping into the air trying to capture the winged invaders.

While chasing insects looks like play behavior, it's important not to let a pet rabbit overexert themselves with too much high-intensity running and jumping. Make sure your rabbit takes frequent breaks and stays hydrated when playing insect chase. Monitor to ensure they don't accidentally injure themselves pouncing on a hard surface.

You don't necessarily need to stop your rabbit from chasing harmless flies and moths unless it becomes obsessive. This natural behavior provides physical and mental enrichment. Just be sure to clean up any squashed insects so your rabbit doesn't try to eat them afterwards! With some limits, you can let your bunny indulge their instinct to hunt down flying bugs now and then.

Would My Rabbit Try to Eat Bees or Wasps?

It's not recommended to allow pet rabbits to eat or even attempt eating stinging insects like bees, hornets or wasps. The venom in these hymenoptera can be very dangerous if injected into a rabbit's mouth, throat or digestive system. Swallowing a stinging insect puts a rabbit at high risk of anaphylaxis, seizures, heart arrhythmias or even death. While the protein in bees or wasps may seem appealing to an opportunistic rabbit, the hazards far outweigh any minimal nutritional benefits.

Some signs your rabbit may have eaten a stinging insect include:

  • Crying out in pain suddenly
  • Excessive drooling
  • Pawing at the mouth
  • Swollen tongue or throat
  • Difficulty breathing

If you observe any of these symptoms after your rabbit attempted to eat an insect, seek emergency veterinary care immediately. Anaphylaxis can progress rapidly in rabbits once stung internally.

To prevent insect stings, make sure your rabbit's outdoor housing has fine mesh screens that don't allow buzzing insects inside. Scan your yard for bee or wasp nests and remove them. Use chemical repellents designed to deter stinging insects from gardens and lawns. Supervise your rabbit closely when they are playing outside. Train them not to chase or eat insects you see. With vigilance, you can prevent a tragic accident involving your curious rabbit and a painful sting.

Would Eating Spiders (Arachnids) Make a Rabbit Sick?

Spiders are not technically insects, but many pet rabbits will readily eat spiders they encounter given the chance. Though spiders can provide nutritional benefits like protein, fat, and vitamins, some risks are associated with rabbits eating spiders.

Some spiders have venom or toxins that could cause adverse reactions if ingested by rabbits. Spider bites on the skin rarely cause issues for rabbits, but if thoroughly chewed and swallowed, toxic substances in the spider could potentially be absorbed internally. Rabbits owners should use caution allowing pet rabbits to eat any spiders other than small, harmless common house spiders.

Other risks of spider consumption include:

  • Injury from sharp limbs getting lodged in the rabbit's mouth or throat

  • Allergic reaction to compounds in the spider's body

  • Overdose of vitamin D from ingesting too many spiders

  • Blocked digestive tract from swallowing large body parts

  • Transmission of parasites or other pathogens

To reduce chances of health problems, do not purposefully feed spiders to pet rabbits. Clear webs and spiders from your rabbit's environment regularly. Supervise outdoor time and intervene if you see your rabbit try to eat spiders or their webs. With prudence, the occasional small spider snack will not harm a rabbit, but use discretion based on spider type and amounts consumed. Monitor for any concerning symptoms after a rabbit eats a spider and contact your exotic vet with any questions.


While insects do not need to be a significant part of domesticated rabbits' diets, they are allowed to eat certain bugs in moderation. Wild rabbits eat more insects as a natural part of their foraging behavior. Crickets, grasshoppers, caterpillars, and some beetles are acceptable insect snacks for pet rabbits. Eating a few small insects can provide supplemental nutrition from protein, fat, vitamins and minerals. However, rabbits should not overindulge on insects or eat those that may be toxic or carry parasites. Monitor your rabbit's appetite for insects and intervene if they seem obsessive. With prudent supervision, allowing your rabbit the occasional insect treat can provide environmental enrichment and satisfies natural foraging instincts.
