19 Tiny Green Bugs That Bite (How to Get Rid of Them?)

19 Tiny Green Bugs That Bite (How to Get Rid of Them?)

Most tiny green bugs that bite are harmless since they feed on plants and small insects. These beneficial creatures are basically uninterested in biting humans, but their bites are highly unpleasant and painful once that happens.

They typically bite to protect themselves from danger, never to attack. However, many people are unhappy seeing these bugs in their homes, so you should know how to recognize them and the consequences of their bites. Let’s take a look.

Types of Tiny Green Bugs That Bite

You can commonly see numerous green bugs in your garden or field, and some can bite you with more or less painful consequences. Luckily, most are entirely harmless, regardless of whether they are herbivores or feed on other insects.

In most cases, they pinch and bite only when they feel threatened. Plus, changes on the skin they cause pass quickly, although they are initially unpleasant.

There is a list of 18 green bugs that can bite you, but you can also find green caterpillars at the article end. These crawling larvae eventually turn into butterflies or moths but can harm your garden in the meanwhile. Plus, they may hurt you in particular circumstances.

1. Green thrips

You can notice green thrips with elongated bodies in the garden on flowers and some veggies. Interestingly, some choose only particular plants, like Citrus or Avocado thrips.

Any of these bug pests can bite you, but it is only their attempt to check whether you are food. After the first bite, they will conclude you are uninteresting and drop off, and this slight pinch won’t cause any side effects.

You can prevent this inconvenience by avoiding white and yellow clothes that are highly attractive for these 0.02 to 0.1 (0.5 – 2.5 mm) long insects. The quickest way to eliminate them is regularly trimming your lawn and vegetation.

2. Green leafhoppers

Green leafhoppers1

These tiny, 0.12 to 0.3 inches (3 – 8 mm) long green bugs have strong hind legs, allowing them long-distance jump. Even though they are strictly herbivorous, they can bite you by mistake while looking for food.

Their bite is harmless and passes by itself without any medical attention. Additionally, they have no tendency to invade homes and are relatively rare in gardens, thanks to a low reproductive rate.

If you find these active insects harmful, you can control them biologically by attracting ladybugs or lacewings, their natural predators.

 

3. Green tiger and six-spotted green tiger beetles

You can recognize two Green tiger beetle species, including:

  • Green tiger beetle (Cicindela campestris) living in Europe and Asia
  • Six-spotted green tiger beetle (Cicindela sexguttata) common in North America

Green tiger beetles come in 11 subspecies living throughout Europe and Asia. These 0.50 to 0.60 inches (12.7 – 15 mm) long bugs typically feed on spiders, mosquitos, wood ants, and various flying insects and their larvae. They are beneficial creatures and rarely bite humans, and the consequences are mild when it happens.

Green tiger and six-spotted green tiger beetles1

Six-spotted green tiger beetles are fast and agile predators living in the US that eat caterpillars, spiders, and ants. You can recognize them by their metallic green, 0.4 to 0.6 inches (18 mm) long bodies. These bugs won’t bite you unless you disturb or try to harm them. Luckily, their bite is harmless and barely painful.

4. Lacewings

Lacewings1

These green soft-bodied insects with four membrane-look wings and golden eyes are approximately 0.75 inches (19 mm) long. Their oblong eggs reach up to 1/16 inches (1.6 mm) in length.

Since these bugs feed on invasive species, like scale insects, you can consider them beneficial in your garden. They live on leaves and rarely bite humans.

In fact, adults never bite, but you can experience a very unpleasant bite of larvae looking for food. Luckily, their bites are painless and followed by skin redness that disappears in a few hours.

 

5. Pale green assassin bug

Pale green assassin bug1

You can quickly identify these 0.50 to 0.70 inches (12.7 – 17.8 mm) long ambush predators by their yellow-brownish wings and green bodies and legs. Their primary goal is to camouflage and sit on plants waiting for insects they feed on.

Even though humans are not in their interest, these bugs can sometimes bite you. Unfortunately, their bite is more painful than any other insect living in your garden.

After experiencing it, you will feel pain for at least a day, while your skin will be swollen for approximately two to three days. Despite the justified anger you probably feel, avoid killing these beneficial bugs feeding on aphids, caterpillars, and mealybugs harmful to plants.

 

6. Katydids

Katydids1

Nowadays, entomologists recognize 6,000 grasshopper species that can be from 0.20 to 5 inches (5 mm – 12.7 cm) long. Longhorn green grasshoppers (bushcrickets) are better known as Katydids.

These nocturnal insects typically reach 0.4 to 2.4 inches (10 – 61 mm) in length. You can recognize them for their entirely green, thick, long bodies and loud mating calls.

Even though they are often considered friendly bugs kept as pets, Katydids can bite humans. Fortunately, their bite is weak and can’t pierce your skin. So, you will only feel a light pinch instead of real pain. In rare cases, their bite is followed by skin irritation and minor itching.

If you hate the noise these bugs make, you can get rid of them by removing plants that attract them, like lemon and orange trees, bursaria, and eucalyptus.

 

7. Ambush bugs

Ambush bugs1

Approximately 0.30 to 0.50 inches (8 – 12 mm) long, Ambush bugs change their body color to green and brown to adapt to their habitat. They are beneficial and destroy damaging plant pests living in gardens.

These creatures can mimic the host flower’s look while ambushing prey, like butterflies, moths, bees, bumblebees, beetles, wasps, and flies. Such behavior makes their feeding technique precise and practical.

Despite the possibility of flying, these insects prefer crawling around flowering plants and spending time in open sunny areas. They never bite humans willingly but react to rough handling and squeezing with unpleasant and pretty painful bites, causing skin swelling.

 

8. Green ticks

Green ticks1

You can see ticks on dogs throughout the year, particularly in the fall, but they can also bite humans. Green ticks are uncommon in the US, and you can confuse them with brown dog ticks looking greenish after sucking blood.

Since these crawling arachnids may transmit diseases, you should consider them dangerous and remove them from your skin with tweezers as soon as possible.

Unlike other green bugs bite, you will feel pain instantly when this tick attacks your skin. If the tissue around the bite becomes swollen or you get a fever, you should visit a doctor immediately.

 

9. Banana cockroaches

Banana cockroaches1

The uniformly pale green Banana cockroach (Cuban cockroach) is a 0.50 to 1 inches (12.7 – 25.4 mm) long insect with a green head and wings that typically live outdoors. Females are always longer than males.

You can spot this invasive flying species around trees at night, mainly near light sources. They can bite you only in a period of scarce food. Otherwise, they will try to eat your nails and dead skin only.

 

10. Green spiders

Green spiders1

These non-toxic arachnids live in woodlands, parks, and gardens and don’t create spider webs like others. Most spider species rarely bite people, but it is sometimes possible when you come across:

  • 10 to 0.30 inches (2.5 – 7.6 mm) long Green crab spider
  • 75 inches (19 mm) long Green lynx spider

When it happens to bite, it is a painful experience that can last for days and sometimes require medical attention. Still, the worst thing is when a female spit venom in the human or animal eye when feeling threatened, causing irritation.

11. Tree crickets

Tree crickets1

Adult Tree crickets are 1-inch (25 mm) long insects that occasionally bite people. Luckily, their short mouthparts can’t pierce human skin and cause significant damage.

You can notice them on trees, shrubs, and flowers in your garden, but be prepared that they look for shelter in the fall. Prepare your home on time to prevent these uninvited guests from entering.

 

12. Praying mantis

Praying mantis1

Praying mantis are 3 – 4 inches (7.62 – 10 cm) long carnivores consuming all types of insects in the garden. They attach their pale and frothy eggs gathered in 1.50 inches (3.8 cm) long two-row mass to twigs.

It is almost impossible to become bitten by these large insects unless while roughly handled. Even then, they can’t damage your skin since they don’t have teeth. These creatures are harmless and don’t transmit any diseases to humans.

 

13. Greenhead ants

Greenhead ants1

Greenhead ants are dangerous predators and scavenger insects that originated in Australia. You can effortlessly distinguish their 0.20 to 0.30 (5 – 7.6 mm) inches long green-blue to green-purple-colored bodies from other insects looking for caterpillars and seeds.

If you ever come across these predators, avoiding them is a better option because their bite is incredibly painful. Even though intensive pain lasts only shortly before disappearing, their potent venom causes numerous health issues, including anaphylactic shock.

 

14. Sweat bees

Sweat bees1

You can recognize 18 Sweat bee types in the US. These beneficial, 0.25 to 0.75 inches (6 – 19 mm) long insects eat pollen and play a significant pollination role. Male bees can’t bite you, while females rarely do that, although they can.

These bees are unaggressive, but you can expect a very unpleasant experience after being bitten if you press them against your skin or handle them roughly. However, their bite is less painful than other bees or wasps and rarely causes complications.

 

15. Green darner dragonfly

Green darner dragonfly1

Green darner is the most sizable and widespread dragonfly living in North America. You can quickly recognize it thanks to its bright green thorax and brownish or blue abdomen, depending on gender.

Most of these elegant, 3 inches (7.6 cm) long insects don’t bite humans. However, large dragonflies can cause pinch-like bites when inappropriately handled. Fortunately, they never severely harm people, and the result of their pinch is short-lived.

 

16. Cuckoo wasps

Cuckoo wasps1

Metallic green or blue Cuckoo wasps live in desert regions worldwide. These small kleptoparasite arthropods are about 0.5 inches (12.7 mm) long and lay eggs in other bees’ nests, allowing hatchlings to eat their hosts.

Be aware that females can’t sting, while territorial males bite only when you endanger their habitat. In most cases, they will only react to harassment and rough handling.

 

17. Dogbane leaf beetles

Dogbane leaf beetles1

This metallic blue-green colored beetle belongs to the largest insect families, with about 35,000 species living worldwide. That number includes over 1,700 bugs from North America.

They are 0.30 to 0.45 inches (7.6 – 11.5 mm) long and feed on toxic flowers, like Indian hemp (dogbane). Even though these creatures can transmit that toxin to people with a bite, they rarely bite humans. Once it happens, you can expect a mild skin reaction.

Be careful with these leaf beetles since they can harm your pets when ingested. They release cardenolides when feeling endangered and may cause dysrhythmias and sometimes even cardiac arrest in dogs.

 

18. Green caterpillars

Green caterpillars1

Believe it or not, you can differentiate tens of green caterpillar types living in your garden, and these with smooth bodies are entirely harmless.

For instance, the Hickory horned caterpillar with a long red spiky horn on one fat-segmented body end is the most horrified and ugliest caterpillar you can find. However, it is entirely harmless and never bites.

The most prominent is a small, plump, and 0.7 inches (1.8 cm) long green oak caterpillar (moth caterpillar). Interestingly, it is the least harmful type you can come across.

However, staying away from a few pretty awkward creatures is better. Even though most are not poisonous, their spikes and spines can sting nasty. It results in pain, rash, constant itching, blistering, and burning sensation on the skin. Believe it or not, one species spits acid when feeling endangered!
