Rove beetles are mainly distributed in southern my country, and Sichuan and Chongqing are also high-incidence areas.

If you accidentally hit a rove beetle with your hands, or crush it, the highly acidic venom "paederin" in the rove beetle's body will cause damage to human skin and cause an inflammatory reaction in the skin.

The skin burned by the venom of rove beetles usually appears as edematous erythema in the form of stripes, patches or dots, covered with white or yellow pustules and papules, and has a noticeable burning pain.

The parts of the body that are generally more easily harmed by rove beetles are exposed skin areas such as the face, neck, and limbs.

Even if you don't swat the rove beetle, avoid skin contact with it!

Many people don't know how rove beetles attack them. In fact, when rove beetles crawl, toxins in their bodies are secreted through the glands in their tails. When they pass through the human body, they will leave some venom on the skin, causing dermatitis. Many people have been successfully "sneak attacked" by rove beetles.

In addition, the venom of the rove beetle may remain on towels, clothing and other items, and indirectly spread to the skin and cause damage.

● The parts that have come into contact with rove beetles should be washed with soapy water or coated with alkaline solution as soon as possible. Calamine lotion can be used to clean the affected area;

● After being exposed to the venom of rove beetles, do not touch the affected area directly with your hands or wipe it casually to avoid expanding the area of ​​skin damage;

● Actively seek medical help and receive treatment under professional guidance to prevent further infection of the affected area and the leaving of scars.

👉Rove beetles are widely found in farmland, forests and mountainous areas, especially in abandoned land and areas with more plants. Try to reduce the number of visits to these places. Wear long clothes and long pants when you can't avoid them and take protective measures;

👉Do a good job of environmental management around the residence, remove garbage and weeds, and reduce the breeding grounds of rove beetles;

👉When you find a rove beetle attached to your skin, do not slap it with your hands. Just blow it away or flick it off gently to prevent the rove beetle's venom from seeping out.

Ticks

Tick ​​bites may cause the spread of diseases such as forest encephalitis, hemorrhagic fever, Lyme disease, brucellosis, and there is a chance of causing anaphylactic shock.

Ticks are generally transmitted between humans and animals, so when you are outside, you must be vigilant when in contact with animals to avoid spreading the infection during contact.

If you find something like a mole on the surface of your skin, be sure to check carefully to see if you have been bitten by a tick!

How to deal with tick bites

● Use tweezers or other tools to gently pull the tick upwards. Do not pick or crush it directly with your hands to prevent the tick's mouthparts from remaining in the skin and causing infection;

● Disinfect the bite site after removing the tick to prevent the spread of germs;

● If you are unable to remove it yourself or if adverse physical reactions occur, go to the hospital for treatment immediately.

Midges

You may be unfamiliar with the term "midge", but friends in Sichuan and Chongqing may be more familiar with it. The scientific name of this annoying little insect is "midge" or "blood-sucking midge".

The areas bitten by midges usually show symptoms of allergic dermatitis such as redness, swelling, pain, and itching. The redness and swelling are larger and more itchy than those caused by mosquitoes. A large number of midges may bite at one time, and in severe cases, papular urticaria may occur.

How to deal with midge bites

● Try not to scratch the bitten area to avoid secondary infection of the wound;

● Wash the bitten area with soapy water to keep it clean;

● If you experience symptoms such as fever, dizziness, nausea, etc., you should seek medical attention immediately and inform your doctor of the experience of being bitten by midges.

Summer and autumn are the peak seasons for mosquito bites

While enjoying the cool summer

Everyone should also prepare for mosquito repellent.
