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.
If you're bitten by fire ants , you may see white, fluid-filled pustules or blisters pictured a day or two after the sting. These last three to eight days and may cause scars.
If the rash persists or becomes infected, contact a medical professional immediately. Bed bugs are blood feeders that depend on blood for their food source, so they must consume blood for survival. One bed bug will usually take more than one bite.
Once a bed bug inserts its mouthparts and finds a suitable blood vessel, it will begin feeding. However, finding the right blood vessel may take more than one injection into the skin. In addition, bed bugs are very sensitive to movement by the host they are feeding on. Therefore, if a sleeping person moves, a feeding bed bug will probably withdraw its mouthparts and begin its search for a blood meal on another part of the body. Scratching bed bug bites and failure to keep the bites clean and disinfected may lead to a secondary infection that can cause further swelling and bleeding.
Children, the elderly, and individuals with weak immune systems, particularly those who are bedridden, may develop secondary infections that result from bed bug bites. Bites on dogs and cats will look much like bites on people, and the pet owner may actually suspect a mosquito or flea bit the pet. As with people, bed bugs do not stay on pets, but return to a protected harborage site after feeding.

Bites from spiders in the UK are uncommon, but some native spiders — such as the false widow spider — are capable of giving a nasty bite. Spider bites leave small puncture marks on the skin, which can be painful and cause redness and swelling. Some spiders bites can cause you to feel or be sick, sweating and dizziness. Bites can also become infected or cause a severe allergic reaction in rare cases.

All ladybirds can bite, but a type called the harlequin ladybird found throughout much of the UK is more aggressive and tends to bite more often.
