There are several options to prevent mosquito bites, including taking vitamin B supplements, using insect repellents, wearing protective clothing, and using mosquito nets. Here are some details about each option:

• Vitamin B: Some dermatologists recommend taking Vitamin B complex, 2 tablets twice a day, or Vitamin B-1, 100 mg daily, to reduce the risk of being bitten by insects, particularly mosquitoes. However, there is no scientific evidence to support the claim that vitamin B can repel mosquitoes.

• Insect repellents: Using insect repellents is a safe and effective way to prevent mosquito bites. The Environmental Protection Agency (EPA) recommends using EPA-registered insect repellents with active ingredients such as DEET, picaridin, IR3535, oil of lemon eucalyptus (OLE), or para-menthane-diol (PMD) . It is important to read the product information to find out how long the protection will last and to follow the product instructions.

• Protective clothing: Wearing long-sleeved shirts and long pants can help prevent mosquito bites. Clothing and gear treated with 0.5% permethrin can also be effective.

• Mosquito nets: Using mosquito nets can be particularly useful when sleeping outside or when screened rooms are not available.

It is important to note that while these measures can reduce the risk of mosquito bites, they do not provide 100% protection. It is also important to take additional precautions in countries where insects carry specific diseases, such as malaria or the Zika virus, and to seek medical attention if necessary.
