Do I need malaria tablets if I use a mosquito net and repellent?

Why you should combine mosquito avoidance with antimalarials


This depends on which country you travel to. If you are travelling to a low-risk area, a mosquito net and repellent should be adequate. But in higher risk areas, malaria tablets should be used alongside mosquito avoidance, i.e. nets and repellent. Mosquito avoidance also protects you against other mosquito-borne diseases, such as Dengue fever.

How to avoid mosquitos?

  1. Use a mosquito net when you sleep. The net should be long enough to reach the floor and should tuck comfortably under your mattress. Ensure there are no tears or holes in the net. You should also spray the net with insect repellent.

  2. Apply insect repellent to your skin. These can be purchased in most pharmacies, especially in countries where mosquitoes are prevalent. Follow the application instructions on the label.

  3. Use insect repellents in your accommodation. These come in the form of candles and sprays. They are different from the insect repellents you would apply to your skin.

  4. Try to keep your skin covered, especially at night.

  5. If it’s available, use air conditioning, as this lowers the room temperature and along with it your risk of being bitten by mosquitos.
