Do Grasshoppers Bite? Facts About These Hopping Insects

In the summer months, a backyard often comes alive with the mesmerizing symphony of chirping crickets and grasshoppers. While mostly harmless, these hopping insects may seem threatening with their perpetual munching. This raises the common question – do grasshoppers bite humans?

The short answer is yes, grasshoppers can bite, but they rarely do so unless prompted or threatened. In this post, we’ll explore the reasons behind grasshopper bites, when they’re most likely to occur, how to identify and treat bites, and fascinating facts about the lifestyle and behavior of these remarkable creatures.

What Are Grasshoppers?

Before diving into whether grasshoppers bite, let’s briefly cover what exactly these insects are. Grasshoppers belong to the suborder Caelifera within the order Orthoptera, which also includes crickets and katydids. These herbivorous insects are found on every continent except Antarctica.

There are over 11,000 known species of grasshoppers, ranging greatly in size and color. Some common varieties include the Differential Grasshopper, the Two-Striped Grasshopper, and the Migratory Locust. Despite their name, grasshoppers inhabit not just grassy areas but various environments like meadows, deserts, and forests.

Do Grasshoppers Bite Humans?

The short answer is yes, grasshoppers are physically capable of biting humans, though they rarely do so unless mishandled or feeling threatened. A grasshopper’s mouthparts, known as mandibles, are designed for chewing and grinding up their plant-based diet. These mandibles can pinch human skin and cause minor injury if the grasshopper is provoked or accidentally squeezed.

Most grasshopper bites are defensive reactions when the insect feels endangered. Factors that may trigger a grasshopper bite include:

  • Attempting to manually catch or handle the grasshopper
  • Accidentally squishing the grasshopper
  • Invading the grasshopper’s territory or nest
  • Threatening actions from humans or animals near the grasshopper

When Are Grasshoppers Most Likely to Bite?

While grasshopper bites are uncommon for most people, there are certain seasons, locations, and scenarios where bites are more likely:

Seasons: Grasshopper bites most frequently occur during the summer and warmer months when grasshopper populations peak and they are highly active.

Locations: Areas with high grasshopper density like fields, meadows, and gardens see more bite incidents, especially if the grasshoppers’ plant food sources are depleted.

Scenarios: Grasshopper bites are more probable when humans or animals directly interact with or disturb grasshoppers, such as through catching, mowing grass, or stepping near nests.

How to Identify and Avoid Grasshopper Bites

A grasshopper bite results in a small, red, swollen bump or marks, not unlike a mosquito bite. In most cases, grasshopper bites are merely irritating and don’t require medical treatment.

However, some individuals may have allergic reactions with symptoms like severe swelling, rash, dizziness, or breathing difficulties. If this occurs, seek medical care immediately.

To avoid getting bitten in the first place:

  • Don’t deliberately attempt to catch or handle grasshoppers
  • Wear insect repellent in grasshopper-prone areas
  • Keep lawn and grasses mowed to deter grasshopper nesting
  • Remove potential grasshopper food sources like vegetation piles

If you do get bitten, promptly wash the area with soap and water. Apply antiseptic creams and cold compresses to reduce swelling and inflammation.

Grasshopper Spit

While not venomous, grasshopper spit can be a potent insect defense mechanism and irritant. Grasshoppers produce this saliva when they bite as a way to lubricate their chewing and release digestive enzymes to break down plant matter.

However, grasshopper spit also contains proteins, enzymes, and other compounds that can trigger allergic reactions, irritation, or infections when coming into contact with human skin. Symptoms like redness, itching, swelling, and rashes may occur depending on the person’s sensitivity level.

Interestingly, grasshopper spit has antibacterial and antifungal properties that evolved to protect insects from pathogens. Some traditional medicine practices have even used grasshopper saliva for its perceived therapeutic benefits. Still, modern medical experts caution against intentional exposure to grasshopper spit and its risks.

Other Fascinating Grasshopper Facts

Beyond the potential to bite, grasshoppers are intricate creatures with some remarkably unique behaviors and traits:

Diet: While grasshoppers are herbivores, their diet is quite varied. They’ll happily munch on grass, leaves, flowers, crops, and cereal grains, and even eat each other (cannibalism) in cases of extreme food scarcity.

Physical Capabilities: Grasshoppers are known for their impressive jumping abilities, using their large hind legs to launch over 20 times their body length! Their strong jaws enable them to chew through tough plant matter.

Reproduction: Male grasshoppers attract mates through loud chirping songs. Females lay eggs in the ground which hatch into nymphs that undergo multiple molts before becoming adults.

Role in Ecosystem: Though seen as pests by some, grasshoppers play a vital part in many food chains as prey for birds, rodents, and other animals. Some cultures even consume grasshoppers as a food source themselves.

Are Grasshoppers Dangerous to Humans?

For the most part, grasshoppers pose little to no threat to humans beyond their potential to bite if mishandled. However, there are a few risks to be aware of:

Allergens: As with many insects, grasshoppers can trigger allergic reactions like anaphylaxis in some people sensitive to their saliva or bodily proteins.

Disease Transmission: Though rare, grasshoppers may carry bacterial diseases harmful to humans like salmonella or E.coli picked up from their environment.

Crop/Garden Damage: Large grasshopper populations or “swarms” can severely damage crops, gardens, and vegetation as they voraciously eat everything in sight.

Vehicular Hazards: When migrating in massive swarms, grasshoppers can create slick hazards on roadways from their spattered body remains.

While fascinating creatures, grasshoppers should generally be observed from a safe distance rather than directly handled.


In summary, grasshoppers can technically bite humans with their pincer-like mandibles, but they rarely do so intentionally. Most bites occur when the insects are threatened, mishandled, or accidentally disturbed. While painful, grasshopper bites don’t usually require medical care unless an allergic reaction develops.

Beyond biting, these unique insects possess some remarkable physical capabilities and behaviors like loud chirping, prodigious jumping, and swarming during migrations. While a potential pest for crops, grasshoppers play a vital role in food chains and some cultures even consume them as food.

By understanding grasshopper bites, biology, and proper handling precautions, we can better appreciate and coexist with these ubiquitous backyard insects. So the next time you hear that iconic chirping melody, you can listen with admiration for these amazing little leapers.
