Most insect bites are harmless, though they sometimes cause discomfort. Bee, wasp, and hornet stings and fire ant bites usually hurt. Mosquito and flea bites usually itch. Insects can also spread diseases. In the United States, some mosquitoes spread West Nile virus . Travelers outside the United States may be at risk for malaria and other infections. To prevent insect bites and their complications: Don't bother insects Use insect repellant Wear protective clothing Be careful when you eat outside because food attracts insects If you know you have severe allergic reactions to insect bites and stings (such as anaphylaxis ), carry an emergency epinephrine kit
