Mosquitoes are a persistent and unavoidable part of summer. But have you ever stopped to wonder why they bite, what makes those bites itch so intensely, and how you can find relief? Here’s a straightforward guide to understanding these common pests.

Why Do Mosquitoes Bite?

It’s a common misconception that mosquitoes bite for food. In reality, both male and female mosquitoes feed on plant nectar for energy. However, only the female mosquito bites animals and humans. She isn’t being malicious; she needs the iron and protein found in blood to produce and develop her eggs. The blood meal is essential for her to reproduce, ensuring the next generation of mosquitoes.

What Do Mosquitoes Look Like?

While there are thousands of mosquito species worldwide, they share a few distinct characteristics. You can typically identify a mosquito by its:

• Slender Body: They have a small, delicate body divided into three parts: a head, a thorax, and an abdomen.
• Long, Thin Legs: They possess six long legs.
• A Pair of Wings: Mosquitoes have one pair of wings that they beat rapidly, creating their signature high-pitched buzzing sound.
• Proboscis: This is the most critical feature—a long, straw-like mouthpart that the female uses to pierce the skin and draw blood.

Why Do Mosquito Bites Itch?

The itch from a mosquito bite is not caused by the bite itself, but by your body’s reaction to the mosquito’s saliva. When a female mosquito pierces your skin, she injects a small amount of saliva that acts as an anticoagulant, preventing your blood from clotting while she feeds.

Your immune system recognizes this foreign saliva as a threat and releases histamine. It’s this histamine that causes the surrounding blood vessels to swell, leading to the formation of the red, itchy bump known as a welt. Essentially, the itch is a sign that your body’s defence mechanisms are working.

How Can I Treat Mosquito Bites?

Finding relief from the maddening itch is often the first priority. Fortunately, several simple remedies can help calm the irritation:

• Wash the Area: Gently wash the bite with soap and cool water to clean it.
• Apply a Cold Compress: Place a cold pack, an ice cube wrapped in a cloth, or a cool, damp cloth on the bite for about 10 minutes. This helps reduce swelling and numb the area.
• Use Over-the-Counter Creams: A hydrocortisone cream or calamine lotion can effectively reduce itching and inflammation.
• Try Oral Antihistamines: For more severe reactions or multiple bites, an over-the-counter antihistamine pill (like cetirizine or loratadine) can help control your body’s histamine response from the inside out.
• Avoid Scratching: This is the golden rule. Scratching can break the skin, increasing your risk of a bacterial infection and prolonging the healing process.

How Can I Prevent Mosquito Bites?

The best way to deal with mosquito bites is to avoid them in the first place. Prevention is key:

1. Use an Effective Repellent: Apply an insect repellent containing DEET, Picaridin, or Oil of Lemon Eucalyptus to all exposed skin.
2. Cover Up: Wear long-sleeved shirts, long trousers, and socks, especially during peak mosquito hours at dawn and dusk. Light-coloured clothing is generally less attractive to mosquitoes.
3. Eliminate Standing Water: Mosquitoes breed in stagnant water. Regularly empty water from flowerpots, birdbaths, old tyres, and any other containers in your yard.
4. Secure Your Home: Ensure your window and door screens are free of holes to keep mosquitoes from getting inside.
5. Use Fans: Mosquitoes are weak fliers. Using a fan when sitting on a patio or deck can create enough wind to keep them at bay.
