To care for a mosquito bite, wash it with soap and water, hold an ice pack on it for about 10 minutes, use an over-the-counter anti-itch or antihistamine cream, and try not to scratch. Most bites cause a puffy, red or itchy bump that fades within a few days, but children and people with immune system problems can have larger reactions. Saela Pest Control is a residential and commercial pest control company, based in Orem, Utah, that offers mosquito control for yards. This guide covers why bites itch, how to treat them at home and which symptoms mean you should see a healthcare provider.
Why do mosquitoes bite?
Only female mosquitoes bite, because, as the CDC explains, most female mosquitoes cannot produce eggs without a blood meal. Male mosquitoes do not bite people or animals. Some people seem to get bitten more than others, and this guide to what attracts mosquitoes to your yard covers the outdoor side.
Why are mosquito bites so itchy?
The itch is your body’s reaction to mosquito saliva. As a mosquito feeds, it pierces the skin with a long mouthpart called a proboscis and injects saliva, and your immune system responds with a bump and itching. The CDC says a bite may show up as a puffy, reddish bump within minutes or as a hard, itchy, reddish-brown bump a day or so later. Severe reactions can include a large area of swelling and redness, low-grade fever, hives or swollen lymph nodes, and they are more common in children, in adults bitten by a mosquito species they haven’t encountered before and in people with immune system disorders.
How to care for mosquito bites at home
The most important step is not to scratch, because broken skin can let in bacteria and the bite can become infected. For a typical bite, the CDC recommends these steps:
- Wash the bite and the skin around it with soap and water.
- Apply an ice pack for 10 minutes to reduce swelling and itching, and repeat as needed.
- Make a paste of 1 tablespoon of baking soda with just enough water, leave it on the bite for 10 minutes, then wash it off.
- Use an over-the-counter anti-itch or antihistamine cream to relieve itching.
When to see a doctor
Most mosquito bites are mild, and the bumps usually go away on their own within a few days. See a healthcare provider if symptoms get worse or if a scratched bite looks infected: red, warm to the touch or with a red streak spreading from it.
Mosquitoes can also spread viruses and parasites, and you can’t tell from the bite itself whether you’ve been infected. For West Nile virus, the CDC reports that about 80% of infected people have no symptoms, while about 20% develop flu-like illness, usually 2 to 6 days after the bite. Watch for these symptoms in the days and weeks after being bitten:
- Fever with a headache.
- Body aches and joint pain.
- Vomiting or diarrhea.
- Rash.
- High fever with neck stiffness.
- Confusion, disorientation or tremors.
- Muscle weakness, numbness or vision loss.
The CDC advises seeking immediate medical attention for high fever, neck stiffness, muscle weakness, confusion or tremors. Fewer than 1% of people infected with West Nile virus develop severe illness affecting the nervous system, but it can lead to hospitalization, so take these signs seriously. The CDC also lists dengue and malaria among diseases mosquitoes spread, and this guide to the health threats posed by pests covers them in more detail.
Preventing bites starts in your yard: the CDC recommends that once a week you empty, scrub, turn over, cover or throw out anything that holds water, since mosquitoes lay eggs near water, and that you use EPA-registered insect repellent outdoors. Saela’s mosquito control service uses mist treatments aimed at resting sites such as shaded foliage and areas beneath porches, along with guidance on reducing standing water. In a March 2026 HomeAdvisor review of Saela’s Denver North location, Pearl M. reported seeing dead insects after the first treatment.
On Google, Saela’s Altamonte Springs, Florida location is rated 4.9 out of 5 from 341 reviews as of October 2026. Between any visits, emptying standing water every week remains the most useful step you can take.
Frequently asked questions
How long does a mosquito bite last?
Most mosquito bites fade within a few days, though larger reactions in children or people with immune system disorders can take longer to settle. See a healthcare provider if a bite gets worse, spreads redness or feels warm.
Should I pop a mosquito bite blister?
No, leave a bite blister alone, because breaking the skin, like scratching, can let bacteria in and lead to an infection. Wash the area with soap and water and use a cold pack or anti-itch cream for relief.
Can you get sick from one mosquito bite?
Yes, one bite from an infected mosquito can transmit a virus such as West Nile, although most bites don’t cause illness and most people infected with West Nile have no symptoms. Watch for fever, severe headache or neck stiffness in the two weeks after a bite, and read more about West Nile virus and how it spreads.
How much does professional mosquito control cost?
Saela quotes mosquito control based on pest type, location, property size, visit frequency and treatment products, so there is no single universal price. The pricing page explains how plans, scheduled visits and return visits work.
