Insects will sting humans only to defend against a perceived threat. When injected into your skin, the venom causes most of the itching and pain associated with the sting. It can also cause an allergic reaction.
Scorpions have a reputation for stinging. Many species have barbed tails equipped with poison, some strong enough to kill a human. The venom injected into your body from the bite or sting of an insect will cause your immune system to respond.
This can cause the throat to tighten and make breathing difficult or cause low blood pressure. Anyone can be bitten or stung by an insect, and bites and stings are very common.

Because spider bites can get infected with tetanus, the CDC also recommends staying on top of your tetanus booster shots and getting one every 10 years. A bite from a poisonous spider like the black widow or brown recluse is extremely dangerous and can cause a severe reaction.
The black widow's bite, which shows up as two puncture marks, may or may not be painful at first. But 30 to 40 minutes later, you may have pain and swelling in the area. Within eight hours, you may experience muscle pain and rigidity, stomach and back pain , nausea and vomiting, and breathing difficulties. You might not have seen the spider that bit you, but always seek medical attention immediately if there's a possibility you could have been bitten by a poisonous spider.
The brown recluse spider is poisonous and usually lives in dark and unused spaces. Some people feel a small sting followed immediately by a sharp pain, while others don't realize they've gotten a brown recluse bite until hours later. Four to eight hours afterward, the bite may become more painful and look like a bruise or blister with a blue-purple area around it. Later, the bite becomes crusty and turns dark. Symptoms of a brown recluse spider bite occur within a few hours and include fever, chills, itching, nausea, and sweating.
Because some people will have a serious reaction that can lead to kidney failure, seizure, and coma, it's important to get medical care at once, according to the National Institutes of Health NIH National Library of Medicine. Be sure to seek medical attention immediately if you could have been bitten by a poisonous spider; call or the American Association of Poison Control Centers at Some tick bites can be dangerous because the insects may carry disease.
Black-legged ticks, formerly known as deer ticks , may carry Lyme disease, and dog ticks can spread Rocky Mountain spotted fever. Up to 30, cases of Lyme disease are reported each year in the United States.
You may also have fever, fatigue, headaches, muscle and joint aches, as well as irregular heart rhythms. But 20 to 30 percent of people who get infected never develop a rash. Symptoms such as swollen or painful joints, memory loss , or other autoimmune responses that mimic those of other diseases may present themselves when Lyme disease is in its advanced stages.
A diagnosis may remain elusive because many doctors will not initially equate these nonspecific symptoms with Lyme disease. Rocky Mountain spotted fever from a tick bite is rare, with about 2, cases per year in the United States. It causes a fever, a headache, muscle aches, and a skin rash. The rash of pinpoint red spots begins on the ankles and wrists after a few days of fever, but later the rash spreads to the rest of the body; in some people, a rash never develops.
Although this infection can be severe — and even fatal — it is preventable and can be successfully treated with prompt medical care, according to the CDC. Another type of tick to avoid is the lone star tick. It can transmit several viruses, the CDC notes. Symptoms of flea bites may begin within hours after you're bitten, and the bites tend to appear in groups of three or four.
You may notice itching, hives, and swelling around an injury or sore, or a rash of small, red bumps that may or may not bleed. Flea bites are most common on your ankles and legs, but may also appear in your armpits, around your waist, and in the bends of your knees and elbows. A flea-bite rash turns white when you press on it and tends to get larger or spread over time. Scratching the rash can lead to a skin infection, according to the NIH National Library of Medicine , and may need medical attention.
In extremely rare cases, fleas are infected with the bacteria that causes plague. The disease can spread from wild rodents to pets and people. Over the past 10 years, as few as 1 and as many as 17 cases of plague were reported in the United States, according to the CDC , most in the rural West. Symptoms of plague include swollen lymph nodes, headache, fever, and chills that appear from one to six days after the bite. Beestings cause a sharp pain that may continue for a few minutes, then fade to a dull, aching feeling.
The area may still feel sore to the touch a few days later. A red skin bump with white around it may appear around the site of the sting, and the area may itch and feel hot to the touch.
If you've been stung by a bee before, your body may also have an immune response to the venom in the sting, resulting in swelling where the sting occurred or in an entire area of your body, including your throat and lungs. If you have this type of allergic response, called anaphylaxis , it is a medical emergency that needs treatment immediately.
Symptoms of a severe allergy to a beesting include hives, swelling, trouble breathing, dizziness, cramps, nausea, diarrhea, and even cardiac arrest. Lice bites are tiny red spots on the shoulders, neck, and scalp from small parasitic insects that can live on your clothes or in your bedding.
Some people may develop a larger, uncomfortable skin rash from lice bites. Continual scratching of the itchy spots could lead to an infection, marked by symptoms including swollen lymph nodes and tender, red skin. An infected lice bite may also ooze and crust over; it will need to be treated by a doctor, but lice are not known to carry other diseases. Ant bites and stings are typically painful and cause red skin bumps.
Some types of ants, like fire ants, are venomous, and their bites can cause a severe allergic reaction. Fire ants bite first to hold on and then sting, giving a sharp pain and a burning sensation.
