Mosquitoes bite to obtain blood, a necessity for female mosquitoes to develop their eggs. They use specialized mouthparts to pierce the skin of animals and humans and feed on the blood that flows from capillaries. When a female mosquito bites, it injects saliva containing anticoagulants to prevent blood clotting, ensuring a steady flow of blood for feeding. Male mosquitoes, however, do not bite and primarily feed on nectar and other plant fluids for sustenance.
Why Do Mosquitoes Bite?
Mosquitoes bite to obtain crucial proteins from blood that are essential for the reproduction and development of their eggs. Only female mosquitoes bite, as they need these proteins to produce viable eggs. When they bite, mosquitoes use their specialized mouthparts to pierce the skin and access blood vessels. They inject saliva that contains anticoagulants to prevent blood clotting, allowing them to feed efficiently. This behavior not only sustains their reproductive cycle but also contributes to their role as vectors for diseases like malaria, dengue fever, and Zika virus, as they can transmit pathogens from one host to another through their bites. Working with professional mosquito exterminators is essential in helping to minimize the risk of mosquito-borne diseases.

Mosquito Bite Symptoms
Mosquito bites tend to occur most often on exposed areas of the body. Symptoms of mosquito bites include:
- Itching: Mosquito bites typically cause itching due to a mild allergic reaction to the mosquito’s saliva injected into the skin during biting.
- Redness: The skin around the mosquito bite often becomes red and inflamed shortly after being bitten.
- Swelling: Mosquito bites can lead to localized swelling, making the area around the bite appear raised or puffy.
- Pain: In some cases, particularly if the bite is scratched excessively, mosquito bites can be painful.
- Small Bumps or Blisters: Some people may develop small bumps or blisters at the site of the mosquito bite, particularly if they have scratched the area excessively.
- Mild Bruising: Mosquito bites can occasionally cause mild bruising around the bite area, especially if the bite is particularly forceful.
- Severe Symptoms: In severe cases, fever, severe headaches, nausea, and fatigue can be a sign of a serious problem. Always consult a medical professional when experiencing these symptoms.
Do Mosquitoes Bite Dogs or Cats?
Pets, including cats and dogs, can indeed be bitten by mosquitoes. Cats, with their thick fur, are less prone to bites, but their noses and ears are still vulnerable. Dogs, on the other hand, are frequent targets of mosquito bites. Apart from causing itchy welts, mosquitoes can transmit diseases to pets just as they do to humans. It’s important to take preventive measures to protect pets from mosquito bites, especially during peak mosquito activity seasons.
