Common Bug Bites in Virginia
Virginia's warm, humid climate makes it a haven for all types of bugs. While most bug bites are harmless, some can spread disease or cause allergic reactions. Knowing how to identify different bug bites can help you seek proper treatment if needed.
Mosquito Bites
Mosquitoes are one of the most common bugs in Virginia during the spring and summer months. When a mosquito bites you, it pierces your skin with its long mouthpart called a proboscis and injects saliva that contains proteins that prevent your blood from clotting.
Mosquito bites usually appear as small, round, red bumps that are very itchy. While mosquito bites themselves are just a nuisance, mosquitoes can transmit dangerous diseases like West Nile virus, malaria, yellow fever, dengue fever, and Zika virus.
Tick Bites and Lyme Disease
Ticks are tiny arachnids that feed on the blood of mammals, birds, and reptiles. Virginia has large populations of ticks, particularly the blacklegged tick (also known as the deer tick) which can transmit Lyme disease through its bite.
Tick bites often go unnoticed because they don't hurt or itch at first. The first sign is usually a expanding rash around the bite area, along with flu-like symptoms like fever, headache, fatigue, and muscle aches. Without antibiotic treatment, Lyme disease can cause long-term joint swelling and pain, nerve pain and weakness, heart palpitations, and memory problems.
Spider Bites
Most spider bites in Virginia come from yellow sac spiders, black widow spiders, brown recluse spiders, and hobo spiders. Their venom can cause redness, pain, swelling, blisters, headache, fever, chills, nausea, and muscle aches.
Black widow and brown recluse spider bites can be particularly dangerous and need emergency medical care. Black widow venom attacks the nervous system while brown recluse venom destroys skin tissue and can cause organ damage.
Chigger Bites
Chiggers are tiny red mites belonging to the Trombiculidae family. They inhabit fields and grassy areas and attach themselves to passing animals and humans. Rather than biting, chiggers pierce the skin and inject enzymes that digest skin cells.
The saliva of chiggers causes severely itchy red welts on the skin that can last up to two weeks. Chiggers tend to concentrate around the ankles, waistline, armpit, or groin where clothing fits snugly against the skin.
Bed Bug Bites
Bed bugs are small, flat, parasitic insects that feed on human blood, usually at night. During the day, they hide in cracks in furniture, floors, and walls. Their bites appear as tiny red bumps or rashes, usually in lines or clusters.
Bed bug bites typically show up on exposed areas like the face, neck, arms, and hands and tend to be extremely itchy. Scratching the bites can lead to skin infections. In rare cases, someone may have an allergic reaction and require medical care for swelling, hives, or breathing trouble.
Flea Bites
Fleas survive by feeding on the blood of their hosts, including mice, squirrels, raccoons, opossums, rats, and pets. If wild animals venture close to a home or pets bring fleas inside, fleas can infest a house.
Flea bites often appear around the feet and ankles in the form of small red dots. Symptoms include intense itching and inflamed bumps or blisters. Secondary bacterial skin infections can develop due to scratching. Some people also have allergic reactions to flea saliva.
Fire Ant Bites
Red imported fire ants are aggressive, stinging insects found throughout Virginia. When threatened, fire ants bite with their sharp mandibles and then sting from their abdomen, injecting venom through a stinger.
Fire ant bites cause a burning sensation, followed by intense itching and a raised welt that forms a white sore at the top. The welts can blister, ooze liquid, and become infected if scratched. Those allergic may react more severely with choking, shock, seizures, or loss of consciousness.
Horsefly and Deerfly Bites
Horseflies and deerflies are large biting flies that feed on the blood of livestock, wildlife, pets, and humans. Only female flies bite, as they require blood to produce eggs.
The bites feel extremely painful and itchy. A red, swollen bump surrounds the bite puncture. The swelling may last a week and cause puffy bruising as the venom triggers an immune response. In rare cases, people have dangerous allergic reactions.
Preventing Bug Bites in Virginia
You can minimize bug bites by taking some safety precautions when spending time outdoors in Virginia:
- Use EPA-approved insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus on exposed skin.
- Wear long sleeves and long pants tucked into socks.
- Avoid wooded and marshy areas where ticks thrive.
- Treat your home and yard for fleas and ticks.
- Don't leave open food or garbage to attract flies, mosquitoes, and ants.
- Repair any cracks or holes in your home's foundation, walls, and screens.
- Set up bedbug monitors under furniture legs and along walls.
Treating Bug Bite Symptoms
Most minor bug bites will heal on their own, but you can take steps for relief:
- Wash the bite with soap and water to remove any remaining saliva/venom.
- Apply hydrocortisone cream or calamine lotion to alleviate redness and itching.
- Take antihistamines containing diphenhydramine (Benadryl) to reduce swelling and itchiness.
- Place an ice pack (wrapped in cloth) on the bite area to reduce swelling.
- Discourage scratching the bites to avoid infections.
- See a doctor if bites show signs of infection or you have an allergic response.
Learning to identify the most common bug bites in your area can help you react appropriately. While most cause only mild irritation, some can potentially transmit disease or trigger dangerous allergic reactions. Protect yourself using repellents and proper attire, treat symptoms for relief, and seek medical care if concerns arise.
