The biologist spoke about the possible consequences of a mosquito bite

Mosquitoes cannot transmit the larva to humans through a bite. Biologist Dmitry Safonov told Izvestia about this on June 27.

He commented on a video of a girl who claimed that a mosquito had bitten her in the eye, depositing a worm larva that had grown over time.

"The mosquitoes have nothing to do with it. This is completely out of the question. As we know, mosquitoes have a fundamentally different reproductive cycle. That is, the female bites a human or animal in order to get the blood that is needed specifically for the maturation of her existing eggs. After that, she looks for a body of water and lays eggs and does it strictly in the water. The mosquito's proboscis itself is designed only to suck blood, not to lay eggs," Safonov said.

According to him, when bitten by a mosquito, only saliva can get into the wound. He noted that the girl most likely saw the infection of the wound with a fly larva, which is called miasis. The biologist emphasized that meat flies can lay eggs in damaged areas of the skin.

If a person notices a parasite after a mosquito bite, the first step is to wash the wound with soap and water and treat it with an antiseptic, Safonov noted. He added that it is necessary to immediately go to the emergency room so that the doctor prescribes a course of vaccine. The biologist stressed that such a course should be completed as soon as possible, on the first day after the bite.

Catching a tick: every third arthropod in Russian forests may be contagious

In some regions of the country, about 40% of ticks are carriers of borreliosis.

Sergei Podkovalnikov, a biology and chemistry teacher and head of the Science is Closer than It Seems project, told Izvestia on May 29 that mosquitoes can gradually react worse to repellents because, like other insects, they are able to adapt to chemicals. As the expert noted, mosquito behavior patterns can change both during evolution and under the influence of individual experience. Some individuals are able to bind a repellent-treated mammal to a food source.

In the spring and summer of 2026, an abnormal increase in mosquito activity was recorded in several regions of Russia. Experts warn that this increases the risk of bites, allergic reactions and the spread of infections, including West Nile fever and dirofilariasis.
