Cicadas and Dogs: What Is the Real Relationship
In short, cicadas are not considered poisonous to dogs. The primary concerns are physical rather than chemical: a dog that eats a cicada risks choking, vomiting, or temporary stomach upset, and very rarely an allergic reaction. Periodical cicadas emerge in predictable, large-scale events that can coincide with peak activity times for pets outdoors. Understanding what cicadas are, why they appear, and how dogs might interact with them helps you take practical steps to reduce risk while preserving your dog’s safety and your peace of mind.
What Cicadas Are and How Dogs Might Encounter Them
Cicadas are insects that spend most of their lives underground as nymphs, feeding on tree roots, before emerging for a short adult stage focused on reproduction. The loud buzzing sound comes from males calling to females. Dogs may encounter cicadas while walking, playing in yards, or hiking in wooded or suburban areas during emergence years. Curiosity can lead a dog to sniff, bat at, or ingest these insects. Emergence timing varies by species, with some broods appearing every 13 or 17 years in specific regions, and annual cicadas can be present most summers in many areas.
Typical Dog Interactions with Cicadas
- Sniffing or investigating the insects on the ground or on low vegetation.
- Bats or playful pawing that may lead to swallowing.
- Occasional eating of shed exoskeletons, which are less fibrous and easier to pass.
- Rare aggressive chewing on large numbers, which raises blockage concerns.
Health Considerations for Dogs Eating Cicadas
Most dogs that eat a cicada experience no serious harm. Cicadas do not produce known toxins, but their hard exoskeleton and size can pose mechanical risks. A single cicada is unlikely to cause issues, but consuming many insects increases the chance of gastrointestinal upset, vomiting, diarrhea, or, in small dogs, a potential obstruction. If your dog shows repeated vomiting, lethargy, loss of appetite, or difficulty defecating after eating cicadas, contact a veterinarian promptly. Allergic reactions are uncommon but possible, so watch for swelling, hives, or breathing changes after exposure.
Signs to Watch For After Ingestion
- Occasional coughing or gagging that resolves quickly.
- Mild, transient vomiting or loose stool.
- Refusal to eat or continued vomiting beyond a single episode.
- Visible distress, panting, or abdominal pain.
Noise, Behavior, and Environmental Impacts
The cicada chorus can be loud and persistent, and noise-averse dogs may show signs of stress or avoidance, such as pacing, whining, or seeking quieter indoor spaces. While this does not pose a physical health risk, it can affect comfort and behavior. Managing noise exposure by limiting outdoor time during peak cicada activity, providing indoor resting areas, or using desensitization methods can help. At the same time, cicadas do not bite or sting, so direct harm from the insects themselves is limited to the risks of ingestion.
Practical Prevention and Safety Strategies
You can reduce risk without altering your dog’s routine dramatically. Simple steps include supervising outdoor time, encouraging calm behavior near insects, and redirecting attention if your dog shows interest in cicadas. Teaching a reliable recall and a leave-it cue can prevent repeated mouthing. For dogs that eat anything they find, a basket muzzle in cicada-heavy areas can be a temporary option. Always ensure your dog has access to fresh water and a safe place to retreat if noise becomes stressful.
Quick Safety Checklist
- Supervise outdoor activities during cicada emergence.
- Use a leash or long line in areas with high insect activity.
- Train and use a leave-it command around swarming insects.
- Offer an indoor quiet zone if noise seems to stress your dog.
- Contact your veterinarian if you see persistent vomiting, lethargy, or signs of obstruction.
When to Seek Veterinary Care
Occasional insect ingestion rarely requires emergency care, but certain signs do warrant professional attention. If your dog vomits repeatedly, shows abdominal pain, has not defecated within a day or two, becomes very lethargic, or struggles to breathe, seek veterinary help right away. A veterinarian can assess for possible obstruction or other complications and offer supportive care. Bringing a sample of the insect or describing it in detail can help the clinician determine the best course of action.
Summary and Takeaways
Cicadas are not poisonous to dogs, yet their size and hard exoskeleton can create physical risks if eaten in larger numbers. The most common issues are mild and self-limiting, such as temporary stomach upset, but choking and intestinal blockage are serious possibilities that require prompt veterinary care. Noise from large cicada emergences may cause stress in noise-sensitive dogs, though the insects themselves do not bite or sting. With supervision, basic training, and prompt attention to warning signs, you can help your dog stay safe and comfortable during cicada season.
