Bites by Insects, Spiders, Scorpions & Snakes

A, Insect Bites,

Insect bites and stings typically cause minor itching, swelling, and pain, which can be treated at home by washing the area, using cold compresses, and applying creams or antihistamines. Seek immediate emergency care for severe allergic reactions (anaphylaxis) like breathing issues, throat swelling, or dizziness. Common culprits include bees, wasps, mosquitoes, fleas, and spiders

Types of Insect Bites and Stings
/ Stinging Insects: Bees, wasps, hornets, and fire ants these often cause immediate, sharp pain. Read more at CDC https://www.cdc.gov/niosh/outdoor-workers/about/insects-and-scorpions.html)
/ Biting Insects: Mosquitoes (itchy, red bumps), fleas (small, itchy, clustered, often on legs), and ticks.

Symptoms
/ Mild Reaction: Redness, itching, burning, and minor swelling around the bite or sting.
/ Severe (Allergic) Reaction: Hives, itching, swelling of the lips/tongue, wheezing, throat tightness, or dizziness.
/ Infection Signs: Increasing pain, swelling, warmth, redness, or red streaks extending from the bite.

Treatment and Care
/ Immediate Action: Wash the area with soap and water, remove any stinger (scrape it off, don't pull).
/ Reduce Swelling/Pain: Apply a cold pack or ice for 10–20 minutes.
/ Itch Relief: Use calamine lotion, 1% hydrocortisone cream, or baking soda paste.
/ Medication: Take oral antihistamines (e.g., Cetirizine, Loratadine) to reduce itching.
/ Pain Management: Use ibuprofen or acetaminophen if necessary.

When to Seek Medical Attention
/ Call 911 immediately if you experience anaphylaxis: Trouble breathing, throat tightness, dizziness, or loss of consciousness.
/ Seek medical attention if: The bite shows signs of infection (pus, spreading redness), or if you develop fever, chills, or body aches.

Prevention Tips
/ Use insect repellent (DEET) and wear long-sleeved clothing.
/ Avoid strong perfumes and brightly colored clothing.
/ Keep food covered when eating outdoors.

B, Spider Bites

Spiders are not insects they are carnivorous Arthropods with eight-legs, two body segments (cephalothorax and abdomen), spinnerets for silk production they possess chelicerae (fanged jaws), but no wings and no antennae. There are over 53,000 recorded species in 139 families worldwide, excluding Antarctica.

Most spiders found in the United States and anywhere else pose no threats to people. Spider bites often cause mild swelling, redness, pain, and itching. These mild symptoms are common and may last from a few hours to a few days. Some people may have more severe reactions. Home treatment is often all that you need to relieve symptoms and treat the skin area.
Home Treatment for yourself:
Don't scratch or rub the skin around the area.
Put ice or a cold pack on the area for 10 to 20 minutes at a time for several hours. Put a thin cloth between the ice and your skin.
Try an over-the-counter medicine for itching, redness, swelling, and pain. Be safe with medicines. Read and follow all instructions on the label.
Take an over-the-counter antihistamine to help calm the itching or swelling.
Put a hydrocortisone 1% cream or calamine lotion on the skin.

However, there are two species in the southern and western United States that can cause serious harm when they are accidentally disturbed - the black widow and brown recluse. Below is a guide to help you identify some of the 2 most common types of spiders and their potential threat to human health. Read more (https://www.pestworld.org/news-hub/pest-articles/spiders-101/)

Brown Recluse Spiders
/ Appearance: Brown recluse spiders are light to dark brown, with a characteristic dark brown violin marking on their back.
/ Region: This species is found in the central Midwest U.S. from Ohio to Nebraska and southward through Texas and Georgia.
/ Habitat: Well known for their secretive or "reclusive" behavior, brown recluse spiders often live outdoors in debris and woodpiles. Indoors, they can be found under furniture, inside storage items and in dark recesses such as baseboards and window moldings. Closets, attics and crawlspaces are the most common hiding places of brown recluse spiders, as they provide warm, dry and dark environments.
/ Threat: Like the black widow spider, the brown recluse spider bites in defense. Bites are usually not felt at first but can produce a stinging sensation followed by intense pain. Restlessness, fever and difficulty sleeping are common symptoms of a brown recluse spider bite. In serious cases, a bite can lead to an open, ulcerating sore that requires medical treatment. Unique Facts: Male brown recluse spiders wander farther from the nest than females and are therefore more likely to crawl into shoes or other attire. Additionally, while other spider species feed on small, flying insects, this species prefers small cockroaches and crickets.


Black Widow Spiders
/ Appearance: Black widows are black and shiny, with a telltale red hourglass shape on the underside of their abdomen. Young black widow spiders appear orange and white, becoming darker and more black in color as they age.
/ Region: This spider species is found throughout United States, but is most common in the southern regions with warm temperatures.
/ Habitat: Black widow spiders tend to seek out dry and dark locations that are protected, such as underneath stones or decks, as well as in hollow tree stumps and in firewood piles. They can also be found in man-made structures such as sheds and barns. Black widow spiders spin their webs near ground level.
/ Threat: While male black widow spiders rarely bite, females are known to be aggressive and bite in defense, especially when guarding eggs. Symptoms of a black widow bite include fever, increased blood pressure, sweating and nausea. Pain from a bite typically reaches a maximum in 1-3 hours. Fatalities are unlikely, as long as proper medical treatment is sought in a timely manner.
/ Unique Facts: Black widow spiders are named after the popular belief that females eat their male counterparts after mating. However, this is a rare occurrence in the natural world.

When should you call for help?
If you know you are bitten by either of these two spiders, contact your doctor now or seek immediate medical care, particularly when

/ you have symptoms of infection, such as:
* Increased pain, swelling, warmth, or redness around the bite or sting. * Red streaks leading from the area.
* Pus draining from the area.
* A fever.

/ You get a blister or sore at the bite or sting area, or the area turns purple. Watch closely for changes in your health, and be sure to contact your doctor if:
/ You have pain or burning at the area after 2 days of home treatment.
/ You have symptoms for more than 1 week.

*Call 911 anytime you think you may need emergency care. For example, call if:
/ You passed out (lost consciousness).
/ You have a seizure.
/ You have trouble breathing.


C, Scorpion Bites

While most Scorpion stings in the United States are painful with skin irritation or swelling but harmless. However, the Arizona bark scorpion in North America is dangerous to humans and can causes envenomation syndrome (read more on scorpion venom toxins). It is important to treat all scorpion bites promptly and monitor for severe symptoms, especially in children and older adults.

Immediate First Aid Steps
1. Clean the Wound: Thoroughly wash the sting site with mild soap and water to reduce the risk of infection.
2. Apply a Cold Compress: Use a cloth soaked in cold water or an ice pack wrapped in a towel for 10–20 minutes at a time to reduce pain and swelling. Do not apply ice directly to the skin.
3. Elevate and Immobilize: If the sting is on an arm or leg, keep the limb elevated at heart level and stay as still as possible to slow the spread of venom.
4. Manage Pain: Take over-the-counter pain relievers such as ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) as needed.
5. Address Itching/Redness: Applying a hydrocortisone cream or taking an antihistamine can help ease local inflammation and itching. Mayo Clinic +8

Critical Warnings
1. Do Not attempt to suck out the venom or cut the wound, as this is ineffective and can cause further injury.
2. Do Not use a tourniquet or take sedatives, which can mask symptoms.
3. Do Not treat the sting as an allergic reaction unless confirmed by a doctor some sources advise against using an EpiPen unless you are specifically having an anaphylactic reaction, as it may worsen heart-related symptoms.

When to Seek Emergency Care
Seek immediate medical attention or call 911 if you experience:
/ Trouble coordinating muscle activity
/ Difficulty breathing
/ Extra salivation
/ Double vision
/ Nausea and/or Fever
/ High heart rate

For expert guidance, you can contact the Poison Help hotline at 1-800-222-1222. They are highly skilled at talking you through next steps depending on your symptoms.

If you’re having mild pain from a scorpion sting, you can put ice on it and take over-the-counter medicine, such as acetaminophen or ibuprofen.
