Afraid of hornets? Let's learn more about these animals! (Hornets)
When we are playing in the yard of a house, or when we have a light on at night, and suddenly an animal flies by with a loud 'ghoo...' sound, we get a little scared, don't we? Most of the time it is a hornet. It is normal for us to feel scared when we see these animals. But like everything, if we are properly aware of these hornets, we can protect ourselves from them without causing unnecessary fear. So today, let's talk about who these hornets are, are they really dangerous, and how to be careful of them.

Who really are the Hornets?

Simply put, wasps are members of the wasp family. But they are a little different from the wasps we see every day. Although we call them 'wasps', scientifically there are several types. The insects we sometimes call ' ground wasps ', which build nests on walls or in the ground (yellowjackets), are actually a type of wasp, not a true wasp. To get a clearer understanding, let's look at these main types.
Type Appearance and information
European Hornet ( Vespa crabro) Also found in Sri Lanka. Brown and yellow/orange in color. Large in size. This is probably the largest species of otter in Sri Lanka.
Northern Giant Hornet (Vespa mandarinia) The largest lizard in the world. About 2 inches long. Found in Asian countries. They are very aggressive.
Yellowjacket Not a true wasp, but in the wasp family. Small in size. Clearly visible yellow and black stripes. Often builds nests on the ground, near the walls of houses.

How do you recognize a Debarek?

It's easy to confuse a yellowjacket with a wasp , but there are some key differences.
  • Size: A true wasp is usually about 1.5 inches long. The queen in the nest is even larger, about 2 inches long. Wasp(yellowjackets) are much smaller than that, about half an inch.
  • Color: Wasps are often striped with dark yellow and black. However, a true European wasp has a mix of brown, orange, and yellow.
  • Stinger: Unlike a bee, a wasp's stinger is smooth, which means they can sting multiple times in a row.

What is the lifestyle of the two?

True wasps are usually forest dwellers. They build their nests in tree hollows, about 6 feet above the ground. However, they can also sometimes be found in old buildings, attics, and inside the walls of houses. In the spring, the queen comes alone and begins to build a paper-like nest by chewing on things like logs and mixing them with her saliva. She then lays eggs , and the first worker wasps that emerge from them take over the tasks of expanding the nest, caring for the other young, and finding food.
The important thing is that a bee colony only lasts for one season. When the cold weather arrives, almost all the bees in the colony die. Only a few newly fertilized queens go to a safe place to spend the winter and start building a brand new colony the following spring. So they don't return to the same colony.

Is the snake really dangerous? What to do about snake venom?

This is our biggest problem. European hornets are not usually going to attack someone who is not bothering them. They will only become aggressive if they feel threatened or if their nest is in danger. But remember, hornets fly at night and are attracted to the outdoors. So they may come into your home at night if you leave your windows and doors open.

If a guy hits you...

Yes, wasps can sting. But most of the time, the pain is similar to a bee sting. If you are not allergic, the pain and swelling will usually subside within a few hours. The best way to avoid a wasp is to stay calm if it comes near you. If you get agitated and start flailing your arms and legs, the wasp will take that as a threat and bite you.

First aid for snakebite poisoning

If you are stung by a wasp, do the following: 1. Wash thoroughly with soap and water. 2. If the stinger is still in the skin, remove it. Do not pull or squeeze it with tweezers. Doing so can cause the venom sac to tighten and the venom to enter the body. Gently remove the stinger with a clean cloth or fingernail. 3. Apply an ice pack to reduce pain and swelling.

Allergic Reactions to Watch Out For

This is the most dangerous and concerning situation. Some people can have severe allergic reactions to wasp and hornet venom. This is called anaphylaxis. This is a medical emergency that can be life-threatening. If you experience any of these symptoms after being stung by a wasp, go to a hospital's Emergency Department (ETU) immediately.
Warning signs of an allergy - go to a hospital immediately!
Difficulty breathing Shortness of breath, feeling of tightness in the chest, rapid breathing.
Swelling of the throat and face Feeling of tightness in the throat, difficulty speaking, swelling of the lips, tongue or face.
Skin characteristics Hives, itching, and redness of the skin.
Stomach ache Stomach ache, vomiting, diarrhea.
Other features Dizziness, loss of consciousness, rapid heartbeat.
If you have had an allergic reaction to an insect sting in the past, talk to your doctor about it and get advice on keeping something like an epi-pen handy for emergency use.

How do you remove spider webs?

If you have a bee's nest in a tree far away in your yard, and it's not bothering anyone, the best thing to do is to leave it there. As we discussed earlier, the nest is abandoned at the end of the season. However, if the nest is inside the house, near a door or window, or in a dangerous place, it will need to be removed.
  • Hire a Professional: This is the safest and most recommended method. Pest ControlThe institutions that do this have special training and safety equipment for this.
  • If you remove it yourself (at your own risk): This is a very risky task. But if you must do it, be extremely careful.
  • Use an aerosol spray specifically designed for wasps and hornets that can be sprayed up to 10-15 feet away.
  • The best time for this task is in the evening or at night, when the bees are less active.
  • But, never shine a flashlight on them. The beetles will fly towards the light.
  • Spray the inside of the cage thoroughly and then immediately move away from there.
  • Spray again if necessary. After all the animals are dead, remove the cage.

Take-Home Message

  • Deer are usually solitary animals, but if you approach their nest or feel threatened, they will definitely attack.
  • A typical spider bite will heal in a few hours. Wash the wound with soap, remove the stinger, and apply ice.
  • If you are experiencing symptoms of an allergic reaction such as difficulty breathing , hives, vomiting , or a swollen throat , it is an emergency. Go to the ETU (Emergency Treatment Unit) immediately without delay.
  • If you have a wasp nest in your home or in a crowded area, it is safest for you and your family to seek professional help to remove it.
