Are Cicadas Dangerous to Dogs?
If your dog just snapped up a cicada, the first question is whether cicadas are dangerous to dogs. In most cases, the answer is no, because cicadas are not poisonous and a single bug is not a toxin problem. The real risks are choking, a stomach upset, or a dog who eats so many cicadas that its gut gets overloaded.
Are Cicadas Safe for Dogs to Eat?
Yes, cicadas are safe for dogs to eat in small amounts. They are not venomous, they do not sting, and they do not carry a poison that makes dogs sick just from being eaten. A healthy dog that grabs one or two cicadas will usually be fine.
The issue is not the cicada itself, but the way dogs eat. Some dogs gulp insects whole, which can irritate the throat or stomach. Dogs that eat a large number of cicadas can end up with vomiting, diarrhea, drooling, or a bellyache. That is a food overload problem, not toxicity.
Can dogs eat cicadas safely?
Yes, dogs can eat cicadas safely when the dog is not choking, and the insect was not exposed to pesticides or lawn chemicals. A freshly emerged cicada in a yard is still not dangerous by default, but chemical exposure changes the picture. The same is true for cicadas that have been dead for a while, because spoiled insects can upset the stomach.
If your dog chews one and moves on, there is nothing to do. If your dog starts coughing, pawing at the mouth, or retching, treat it as a possible choking issue and act right away.
Are cicadas poisonous to dogs?
No, cicadas are not poisonous to dogs. They are insects with a hard outer shell, wings, and six legs, but they do not produce a poison that makes dogs ill on contact or ingestion. The word that fits best is not poisonous, but irritating if eaten in excess.
That is why the question is not whether cicadas are poisonous, but whether your dog ate a small amount or a large amount. One bug is a snack-sized event. A mouthful of cicadas is a different situation.
When Cicadas Become a Problem
Cicadas can cause trouble in three specific ways, choking, stomach upset, and accidental exposure to pesticides. The shell and legs are crunchy and awkward to swallow, so a small dog or a dog that bolts food can have a harder time than a calm chewer. Dogs that gorge on insects can also end up with vomiting or loose stools.
The biggest red flag is not the insect itself, but where it came from. Cicadas from treated lawns, sprayed shrubs, or areas with insecticides can carry chemical residue. If you use yard treatments, assume anything living there can pick up that residue and keep pets away from the area after application.
Will eating cicadas hurt my dog?
One cicada will not hurt most dogs. A few cicadas usually do not cause harm either. The risk rises if your dog is small, if the dog eats many cicadas at once, or if the dog shows signs of choking or an upset stomach.
Watch for repeated gagging, vomiting, diarrhea, refusing food, or unusual tiredness. Those signs point to a digestive reaction or a separate problem that needs attention. If breathing looks strained or the gums turn pale or blue, that is an emergency.
What about cicadas eaten by dogs in big numbers?
Dogs that raid a swarm or spend time snapping up cicadas from the grass can eat far more than a normal snack. That can irritate the stomach and, in rare cases, cause a blockage if a dog swallows a lot of exoskeleton material at once. Small dogs are at higher risk because the same amount of food-like material fills more of the gut.
If your dog ate a pile of cicadas and now has vomiting, repeated gagging, or a swollen belly, call a veterinarian. Keep the dog from eating more, offer water in small amounts, and do not force food.
What To Do Right After Your Dog Eats a Cicada
The right response is simple, stay calm, check the mouth, and watch for symptoms. Do not try to make your dog vomit. Do not give home remedies that were made for people. The goal is to see whether the dog swallowed one insect cleanly or needs help for choking or digestive trouble.
- Look at your dog’s mouth only if it is safe to do so.
- If you see a cicada lodged near the lips or teeth, remove it only if you can do that without getting bitten.
- Offer a small amount of fresh water.
- Watch your dog for the next few hours.
- Call a veterinarian if vomiting, choking, swelling, or severe lethargy starts.
If the dog is breathing normally, acting alert, and not vomiting, the situation is usually mild. A single cicada does not require panic. The main job is to notice the difference between a harmless snack and a real reaction.
When should you call the vet?
Call a veterinarian right away if your dog cannot swallow, keeps coughing, has trouble breathing, vomits more than once, or seems weak. Also call if you know the cicadas were exposed to pesticides, fertilizer sprays, or other yard chemicals. Chemical exposure matters more than the insect itself.
If your dog is a toy breed, brachycephalic, or has a history of swallowing things whole, act faster. Smaller airways and smaller digestive tracts leave less margin for error.
Why Dogs Go After Cicadas
Dogs are curious, fast, and opportunistic. A cicada making noise in the grass can trigger a chase response, and the insect’s sudden movement makes it feel like prey. For many dogs, the appeal is simple, the bug moves, the dog bites, and the game starts.
Cicadas are harmless to the dog as an animal, but they are a novelty food item. Dogs do not know that they are not supposed to eat them. That is why leash control, yard supervision, and quick redirection work better than trying to teach a dog the biology of cicadas after the fact.
How to keep your dog from eating cicadas
Use a leash during heavy cicada activity and keep dogs away from areas where they gather on tree trunks, fences, and low shrubs. In the yard, call your dog inside during peak cicada movement if it is obsessively hunting bugs. A short, supervised bathroom break is safer than letting a dog graze on insects.
If you want to reduce the temptation, keep grass trimmed and clean up dead cicadas from patios and pathways. Dogs notice scent and motion, so reducing both cuts down on bug-chasing behavior.
What Pet Owners Should Know About Cicadas
Cicadas are large, loud insects with strong wings, prominent eyes, and a hard exoskeleton. They spend years underground as nymphs, then emerge in huge numbers as adults to mate. Their shell-like body is what can bother a dog’s mouth or stomach, especially if the dog eats several at once.
Ecologically, cicadas are part of the food web. Birds, reptiles, fish, and mammals eat them, and dogs are simply another curious eater in that list. But dogs are not built to crunch through insects all day, so a cicada is more of a one-off snack than a suitable treat.
Are cicadas bad for dogs to eat?
No, cicadas are not bad for dogs to eat in the sense of being toxic or dangerous in small amounts. They become a problem when the dog eats too many, chokes, or swallows insects exposed to yard chemicals. That is the cleanest answer to the question of whether cicadas are harmful for dogs to eat.
If you saw your dog eat one cicada and it is now acting normal, the answer is almost always no harm done. If your dog ate several and is now sick, the insect shells and quantity are the likely cause.
Frequently Asked Questions
Are cicadas dangerous to dogs?
No, cicadas are not dangerous to dogs in the toxic sense. The main concerns are choking, vomiting, diarrhea, and pesticide exposure. A dog that eats one cicada is usually fine.
Is it safe for my dog to eat cicadas?
Yes, it is safe for most dogs to eat a cicada or two if the insects were not exposed to chemicals and your dog is swallowing them without trouble. It is not safe to let a dog gorge on them.
Are cicadas harmful for dogs to eat?
They are not harmful in small amounts. They can be harmful if the dog eats a large number, has a sensitive stomach, or the cicadas were exposed to pesticides.
Can dogs eat cicadas?
Yes, dogs can eat cicadas. They are not poisonous, but they are not a planned part of a healthy diet either. Think of them as an accidental snack, not a treat to encourage.
Is it okay for dogs to eat cicadas?
It is okay if it happens by accident and your dog remains normal afterward. It is not okay if your dog is choking, vomiting, or eating cicadas from a treated yard.
Are cicadas safe for dogs to eat if the dog is small?
Small dogs face more risk because a shell, wing, or legs can be harder to swallow and a few cicadas make up a bigger load in the stomach. Watch small dogs more closely after they eat any insect.
