Identifying Insect, Bugs and Their Bites

Ticks

Many bugs give us reason for pause, including spiders, chiggers, bees and lice. But few get under our skin -- quite literally -- like the tick. If you enjoy the outdoors, be careful of ticks -- they can attach as you brush past grass and plants. Ticks don't always carry diseases, and most bites are not serious. But they can carry diseases including Lyme disease and Rocky Mountain spotted fever.

Tick Bites

Once a tick latches onto skin, it often moves to the warm, moist armpits and groin -- feeding on blood and passing on any disease it carries. A tick bite can also trigger an allergic reaction. If you have a tick, it is important to remove it properly. To prevent tick bites, keep your arms, legs, and head covered when outdoors. Use tick repellant with DEET on skin or clothing, or products with permethrin on clothing. Check for ticks after spending time in grassy or wooded areas.

Lyme Disease

In the U.S., the Western black–legged tick and the deer tick can carry Lyme disease bacteria. Infected ticks usually don't spread the disease until they've been attached for at least 36 hours. The first sign of infection is often a circular skin rash. Early symptoms may also include fever, headache, and fatigue. Untreated Lyme disease may spread to other parts of the body, including the muscles, joints, heart, and nervous system. Most cases of Lyme disease can be treated successfully with antibiotics.

Black Widow Spiders: Venomous!

Wood piles and tree stumps -- that's where venomous female black widows hide. She is long-legged and glossy black, with a distinctive orange, red, or yellow "hourglass" shape on her underside. These spiders are roughly 1/3 inch wide and 1.5 inches long, counting their long legs.

Black Widow Spider Bites

Black widow spider bites may cause stabbing pain in the bite area, but they can also be painless. Look for one or two red fang marks, redness, tenderness, and a nodule at the bite site. Severe muscle cramps, nausea, vomiting, seizure, and a rise in blood pressure may follow soon after. Get medical care immediately. Anti-venom medicine is available. If possible, bring the spider with you for positive identification.

Nasty Bite

Hiding in attics and closets -- in Midwestern and Southern states -- that's where you'll find brown recluse spiders. The spiders range in color from yellowish-tan to dark brown, with darker legs. Their venom is toxic, and their bite can sometimes cause serious wounds and infection. Yet you may not even feel their bite until later.

Brown Recluse Spider Bites

When the brown recluse bites, it is often painless -- then skin may redden, turn white, blister, and becomes painful. Sometimes an ulcer forms. These bites can be deadly in extremely rare cases. Get medical care if you have been bitten by a spider. If you can, bring the spider with you for positive identification.

Head Lice: Itchy!

In hair -- that's where you'll find lice. They like to hide in the neck area of the scalp and behind the ears. If you have lice, you likely got it from sharing a hat, brush, or other item with a person who has lice. Lice are itchy, but scratching can lead to infection. In severe cases, hair may fall out.

Head Lice Remedies

To kill lice and their eggs (called nits), use lotions, creams, or shampoos from the drug store or prescribed by your doctor which are designed specifically for lice. Wash clothing, bedding, and brushes in hot water and dry in a hot dryer of dry clean to prevent the spread of lice. Check all household members, and treat everyone who has nits or lice.

 

 Fleas: Not for Pets Only

Fleas are small, wingless, agile insects that live off the blood of their host -- and they don't just bite pets. They dine on people, too.

Flea Bites

Some people are very sensitive to flea bites -- but scratching can cause a wound or infection. The best solution is to get rid of fleas on pets and in your home. Keep pets out of your bed and be sure to vacuum rugs daily. Spray insecticides according to directions on infested areas. Consider using a veterinary approved insecticide on your pet.

Bee, Wasp, Hornet, Yellow Jacket

When certain types of bees sting, they lose their stinger and die. But a wasp, hornet, or yellow jacket can inflict multiple stings because it does not lose the stinger. These stings can cause serious reactions in people who are allergic to them.

 

Bee, Wasp, Hornet, Yellow Jacket Stings

If you don't have an allergic reaction, simply remove the stinger, clean the sting site, apply ice, take oral antihistamine for itching, and take ibuprofen or acetaminophen for pain relief. If you have a severe anaphylactic reaction, use an epinephrine auto-injector if you have one. Call for emergency care. Lie down and carefully remove the stinger without squeezing the venom sac.

Fire Ants: Ouch!

Fire ants look much like ordinary ants -- and are found in most of the Southern states. They produce large mounds in open areas and are aggressive when disturbed. During an attack, the fire ant latches onto the skin with its jaw, then stings from its abdomen. It may inject venom many times.

 

Fire Ant Stings

The fire ant sting typically causes red lesions that burn and itch. Painful pus-filled lesions can also occur. Cold packs, pain relievers, and antihistamines can help relieve the discomfort. A large number of stings may trigger a toxic or severe life-threatening allergic reaction. Get emergency care immediately if needed.

Bullet Ant

Paraponera Clavata is a specie of ant, commonly known as the bullet ant, named on account of its powerful and potent sting due to it venom. These ants are found in Honduras, Nicaragua and Costa Rica from the north, and in Venezuela, Colombia, Ecuador, Peru and Brazil from the south and is ranked as the most painful according to the Schmidt sting pain index, given a "4+" rating, above the tarantula hawk wasp and, according to some victims, equal to being shot, hence the name of the insect.

 

 

Chiggers: Itchy!

Contrary to popular belief, chiggers are not insects; they are arachnids. Specifically, chiggers are the juvenile (or larval) form of a family of mites called Trombiculidae. They only dine on humans in their juvenile form. Their bites are painless, but lesions are very itchy. Itching usually peaks a day or two after the bite occurs.

Chigger Bites

After a few days of being attached to the skin, chiggers fall off -- leaving itchy red welts. Over-the-counter products can help relieve itching. See your doctor if the skin appears infected or the welts appear to be spreading.

 

Scabies: Stealthy Pests

When scabies mites get into the skin, they can cause a big skin problem. The mites spread through skin-to-skin contact with an infected person -- or by sharing towels, bed linens, and other objects.

Treating Scabies

Intense itching and skin sores don't appear until several weeks after mites get into skin. The itching is very severe and usually worse at night. The rash typically is seen on the sides and webs of the fingers, the wrist, elbows, genitals, and buttock. You'll need prescription lotion or pills to get rid of scabies. Wash all clothes, towels, and bedding in hot water and dry in a hot dryer or dry clean.

Bedbugs: Hitching a Ride

Their name tells the tale, as these tiny insects tend to hide in bedding. They are often found in hotels, shelters, and apartment complexes. They will hide in suitcases, boxes, books, wall cracks and shoes to be near or close to a human environment or food supply and can hitch a ride into your home aboard luggage, pets, and boxes.

Bedbug Bites

Bedbugs leave itchy, red bites on the skin, usually on the arms or shoulders. More of a nuisance than a health hazard, it is possible to develop an infection from scratching. If you have an allergic skin reaction, use creams with corticosteroids and take oral antihistamines -- and see your doctor.

Scorpions: Deadly!

Not all scorpions are venomous, but those that are can be deadly. Scorpions are found mostly in the Southern and Western states. Symptoms of a sting include pain, swelling, itching, vomiting, increased sweating, and vision problems. Get medical care immediately.

Deerflies: Painful!

These biting flies live in wetlands, forests, and other damp environs. Keep these painful bites clean and avoid scratching to help prevent infection. Some types of deerflies spread Tularemia, an infectious bacterial disease that requires medical attention. Insect repellant and protective clothing help prevent deerfly bites.

Mosquitoes: More Than Irritating!

Mosquitoes aren't just annoying. Scratching a bite can cause a skin infection. Also, mosquitoes can carry West Nile virus, dengue fever virus, and other diseases. To protect yourself from mosquitoes, apply insect repellent and cover up when you go outdoors. Use window screens, and get rid of standing water in your yard.
