\u27a1\ufe0f Only female mosquitoes bite, as they need blood to develop their eggs.
\u27a1\ufe0f A mosquito bite usually causes a small, itchy red bump, accompanied by slight swelling of the skin.
\u27a1\ufe0f In most cases, mosquito bites are harmless and disappear within a few days.
\u27a1\ufe0f Certain species, such as the tiger mosquito, can carry diseases (dengue, chikungunya, Zika), but these cases remain rare in France.
\u27a1\ufe0f To avoid bites, you can minimise standing water, use repellents and install mosquito nets.<\/p>\n<\/div>\n<\/div>\n\n\n\n
Why do mosquitoes bite?<\/h2>\n\n\n\n![\"\"](\"https:\/\/www.sereni-d.com\/wp-content\/uploads\/2026\/03\/moustique-qui-pique.jpg\")
<\/figure>\n<\/div>\n\n\nContrary to popular belief, not all mosquitoes bite. Only female mosquitoes are responsible for bites<\/strong>. They need blood to ensure the development of their eggs.<\/p>\n\n\n\nThe female mosquito is a biting-sucking insect, much like bed bugs<\/a>. When she bites the skin, she inserts her mouthparts into the epidermis to reach a small blood vessel. She then draws a few drops of blood, which provide her with the proteins needed for her eggs to mature.<\/p>\n\n\n\nAfter this blood meal, the female can lay several dozen eggs in stagnant water (puddles, plant saucers, gutters, etc.).<\/p>\n\n\n\n
\n\nGood to know: a single female can sting several times in her lifetime.<\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\nHow can you tell if you\u2019ve been bitten by a mosquito?<\/h2>\n\n\n\n
When a mosquito bites, it injects a small amount of saliva into the skin. This substance prevents the blood from clotting and makes it easier for the mosquito to suck blood.<\/p>\n\n\n\n
It is precisely this saliva that triggers the skin reaction:<\/p>\n\n\n\n
\n- local redness,<\/li>\n\n\n\n
- swelling of the skin,<\/li>\n\n\n\n
- the appearance of an itchy mosquito bite.<\/li>\n<\/ul>\n\n\n\n
A mosquito bite is usually easy to identify. It appears a few minutes after the insect has bitten the skin and manifests as a small red bump that is very itchy.<\/p>\n\n\n\n

<\/figure>\nWhat does an infected mosquito bite look like?<\/h3>\n\n\n\n
In most cases, a mosquito bite is harmless and clears up within a few days. However, it can sometimes become infected, mainly due to<\/strong> repeated scratching<\/strong>, which damages the skin and allows bacteria to enter.<\/p>\n\n\n\nIf an infection occurs, the symptoms are as follows:<\/strong><\/p>\n\n\n\noccasionally a mild fever or general malaise; in rarer cases, this may last for several days, depending on the individual\u2019s susceptibility.<\/p>\n\n\n\n
\n- significant redness around the bite<\/li>\n\n\n\n
- more pronounced swelling than with a typical bite<\/li>\n\n\n\n
- pain or a sensation of heat in the skin<\/li>\n\n\n\n
- the presence of pus or a yellowish fluid<\/li>\n\n\n\n
- a mosquito bite that grows larger instead of disappearing<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n\n\n
The affected area may also become hard and very sensitive to touch.

<\/figure>\n<\/div>\n\n\nMosquito bites are common in babies during the warmer months.<\/p>\n\n\n\n
\n\nA mosquito bite on a baby can be more noticeable and more striking than on an adult.<\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\nDon\u2019t worry, this is normal; it\u2019s down to the baby\u2019s immune system, which is still developing. Babies\u2019 skin is also more delicate and reacts more strongly to the substances injected by the mosquito.<\/p>\n\n\n\n
To relieve a mosquito bite in an infant, a few simple steps are all it takes:<\/p>\n\n\n\n
\n- clean the area with water and a mild soap,<\/li>\n\n\n\n
- apply a soothing ointment suitable for babies if necessary,<\/li>\n\n\n\n
- use a cool compress to reduce the itching sensation,<\/li>\n\n\n\n
- prevent the baby from scratching the area.<\/li>\n<\/ul>\n\n\n\n
If the baby scratches a lot, remember to trim their nails regularly to minimise the risk of infection.<\/p>\n\n\n\n
If the bites do not clear up within a few days and there are signs of infection or an allergic reaction (severe swelling, fever, hives, etc.), consult your doctor.\u00a0

<\/figure>\nA normal mosquito bite vs a tiger mosquito bite<\/h3>\n\n\n\n
Tiger mosquito bites generally look similar to those of a common mosquito, but they can be more painful and cause more irritation in some people.<\/p>\n\n\n\n
\n\nA tiger mosquito bite can cause a bump that is slightly more swollen and inflamed than a typical mosquito bite. The skin reaction can vary from person to person.<\/strong><\/p>\n\n\n\n<\/p>\n<\/div>\n<\/div>\n\n\n\n
The main difference lies primarily in the behaviour of the tiger mosquito<\/strong>:<\/p>\n\n\n\n\n- it bites mainly during the day, unlike the common mosquito, which tends to bite at night,<\/li>\n\n\n\n
- it is more aggressive and more active,<\/li>\n\n\n\n
- it often lives close to human dwellings.<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n
Can the tiger mosquito transmit diseases?<\/h3>\n\n\n\n![\"\"](\"https:\/\/www.sereni-d.com\/wp-content\/uploads\/2026\/03\/zoom-moustique-tigre.jpg\")
<\/figure>\n<\/div>\n\n\nYes. The tiger mosquito is known to be a <\/strong>potential vector of viral diseases<\/strong><\/a>. It is for this reason that health authorities are keeping a particularly close eye on its spread.<\/p>\n\n\n\nIn theory, it can transmit the following diseases:<\/p>\n\n\n\n
\n- dengue fever,<\/li>\n\n\n\n
- chikungunya,<\/li>\n\n\n\n
- the Zika virus.<\/li>\n<\/ul>\n\n\n\n
\ud83d\udc49 These diseases remain rare in mainland France<\/strong>, but isolated cases may occur when infected people return from areas where these viruses are circulating. The tiger mosquito can then become a local vector if it bites an infected person.<\/p>\n\n\n\nTo limit the spread of the tiger mosquito, remember to remove any standing water in and around your home.<\/p>\n\n\n\n
