- Work or spend a lot of time outdoors
- Live in warmer climates
- Fail to use proper protection
- Forget to use flea and tick preventive measures for pets
- Collect insects as a hobby
- Mild swelling
- Shortness of breath
- Swelling, redness, or hives covering most of your body
- A feeling that your throat is closing up
- Nausea or vomiting
- Chills, muscle aches, or cramps
- Abdominal pain
- Headache sweating
- Wash the affected area with soap and water.
- Place an ice pack or cold compress on the affected area. Use the ice for about 15 minutes every few hours. Do not place the ice directly on the skins
To help relieve itching consider:
- Use calamine lotion
- Topical steroid cream, such as hydrocortisone
- To reduce swelling or pain, consider acetaminophen or ibuprofen.
- To remove a stinger—Use a sharp edge, such as a credit card. Gently scrape the edge over the site to push the stinger out.
To remove a tick—Use tweezers to grasp the tick by the head. Pull the tick gently but firmly up and away from the skin. Hold the tick just above the skin until it releases its bite.
- Ticks can carry infections like Lyme disease or Rocky Mountain Spotted fever. The sooner you remove the tick the smaller the chance of infection.
- Note: if the tick's mouth breaks off in the skin, it can be left there. It does not pose an infection risk. The mouth will be pushed out during normal skin growth.
- Emergency treatment to stabilize life-threatening symptoms
- Medications to reduce swelling and other allergic reactions
- IV fluids
- Use insect repellents. These work against biting insects such as mosquitoes.
- Reduce the amount of exposed skin. Wear long sleeve shirts and pants when possible.
- Avoid sweet-smelling perfumes, deodorants, lotions, hair sprays, and colognes.
- Avoid wearing bright colors.
- Wear gloves when gardening.
- Stay inside at dawn and dusk. Mosquitoes are most active during these times.
- Stay away from areas where mosquitoes breed, such as areas around still water.
- Use caution around areas where insects nest. Areas include walls, bushes, trees, and open garbage cans.
- Be cautious in areas where spiders might be hiding. Areas include undisturbed piles of wood, seldom-opened containers, or corners behind furniture.
- Do not disturb bee or wasp nests.
- Keep foods covered as much as possible when eating outdoors.
- Cover outdoor garbage cans with tight-fitting lids.
- Remove any areas of still water from around your house. This may include turning over lids or pots around your yard that have collected rainwater.
- Use flea and tick control for pets. Regularly treat your home for fleas during warmer months.
- Treat fire ant mounds with insecticides.
