During the summer, insect bites and stings become one of the most common annoyances. Mosquitoes appear more frequently due to the heat and humidity, while jellyfish may be present on beaches and coastal areas. Although most bites and stings are not serious, they can cause pain, itching, swelling, and irritation.

Knowing how to act in each case is important, because not all bites are treated the same way. In fact, some home remedies can worsen the situation if applied incorrectly.
Mosquito bites: why do they itch so much
When a mosquito bites, it injects saliva into the skin to facilitate blood sucking. The immune system reacts by releasing histamine, which causes the characteristic itching, redness, and swelling.
In some people, especially children or people with sensitive skin, the reaction may be more intense and last for several days.
How to treat a mosquito bite
The first step is to wash the area with soap and water. Afterward, you can apply a cold compress to reduce inflammation.
To relieve itching, post-bite products with soothing ingredients can be used, such as:
Ammonia
Corrugated iron
Aloe vera
Soothing extracts
Topical antihistamines, when indicated
It is important to avoid scratching, as it can break the skin and lead to infection.
How to prevent mosquito bites
Prevention is key. Some recommendations are:
Use appropriate repellent
Avoid strong perfumes
Wear light-colored clothing
Use mosquito nets if necessary
Avoid areas with stagnant water
For children, pregnant women, or those with sensitive skin, it is advisable to choose repellents appropriate to each case.
Jellyfish stings: what happens to the skin
Jellyfish have stinging cells in their tentacles. Upon contact with the skin, they release irritating substances that can cause:
Intense pain or burning sensation
Redness
Inflammation
Linear marks on the skin
Burning sensation
The intensity depends on the type of jellyfish, the affected area, and the person's sensitivity.
What to do if you get stung by a jellyfish
In the event of a jellyfish sting, it is important to act correctly:
Get out of the water calmly.
Do not rub the area.
Remove tentacle remains with tweezers or a rigid card, never with bare hands.
Wash the area with seawater, not fresh water.
Apply local cold wrapped in a cloth.
Consult if the pain is intense or the reaction spreads.
What not to do in case of a jellyfish sting
There are many myths about jellyfish stings. It's important to avoid:
Apply fresh water directly
Rub with sand or a towel
Use alcohol
Applying home remedies without guidance
Scratch the area
These actions can activate more stinging cells and worsen the reaction.
When to consult a professional
For both mosquito and jellyfish stings, you should check if the following symptoms appear:
Intense swelling
Persistent pain
Difficulty breathing
Dizziness
Fever
Signs of infection
Bites on the face, neck, or sensitive areas
In young children or people with allergies, it is best to act with special caution.
