Allergic Reactions to Mosquito Bites in Kentucky:
Understanding the Risks for Children and Adults
Pest Expert Matthew S. Hess – 06/04/2025
Mosquitoes begin to emerge in Kentucky with the end of cold weather and your Kentucky property could be harboring them. With their emergence comes the potential for itchy bites and, allergic reactions , as well as the potential for common mosquito-borne illnesses. While most people experience mild discomfort from mosquito bites, some individuals, especially children, may have more severe reactions that warrant attention. My son (Images below) had severe allergic reactions that were unlike anything I had ever seen before. For instance, he was once bitten by a mosquito on the forehead, and his head swelled dramatically to the point his eyes were swollen shut. Not only was his head swollen and his eyes swollen shut, but the area of the bite was also extremely hot to the touch. These types of allergic reactions can be very frightening. Understanding how allergic responses work is essential for effectively managing and treating the symptoms.
From the front angle view, you can see the severity of the swelling leading into the eyes and the blackening of the eyes.
This image from the Doctor’s office shows the severity of swelling on the right side of the head (left side from our perspective view). Although this picture does not fully demonstrate the true severity, it clearly shows magnificent swelling if you pay special attention to the slope of the forehead to the left side (our right).
What Causes Allergic Reactions?
When a mosquito bites, it injects saliva into the skin, which contains proteins that prevent blood clotting and trigger an immune response. For some people, this immune response can be exaggerated, leading to allergic reactions. Children are particularly susceptible due to their developing immune systems, but adults can also experience heightened sensitivity to mosquito bites. Once the body identifies something as dangerous (the allergen), whether it is or isn’t actually dangerous, the immune system reacts to that “danger” by producing antibodies to target the “danger” or allergen. When exposure to the same allergen occurs, especially repeated exposure, antibodies trigger the release of histamines that lead to the characteristic symptoms of an allergic reaction.
Symptoms of Allergic Reactions
The symptoms of allergic reactions to mosquito bites can vary in severity. While many people may not experience any reaction at all, some people may experience extreme reactions. Additionally, pets may exhibit allergic reactions as well. Reactions may include:
- Localized Swelling: A common reaction where the bite site becomes swollen and red, often accompanied by itching.
- Hives: Raised, itchy welts that can develop around the bite area or other parts of the body.
- Pain and Discomfort: Some individuals may experience significant pain at the bite site, which can be especially distressing for children.
- Fever: Sometimes a fever may accompany other symptoms of a mosquito bite.
- Systemic Reactions: In rare cases, individuals may experience more serious symptoms such as difficulty breathing, dizziness, or anaphylaxis, which requires immediate medical attention.
Once a bite has prompted an allergic reaction, itching is usually the first response. For children, especially, this can be concerning as consistent scratching of the bite site can induce infection, creating an even worse situation. Stopping the itch can aid in preventing further problems.
Control and Prevention Measures
To minimize the risk of allergic reactions to mosquito bites, taking steps to reduce mosquitoes and prevent their bites is essential. To help control and prevent mosquitoes and their bites, try the following:
- Use Insect Repellent: Apply EPA-approved insect repellents containing DEET, picaridin, or oil of lemon eucalyptus to exposed skin, especially for children playing outdoors. Personal DIY mosquito control is important.
- Dress Appropriately: Encourage wearing long sleeves, long pants, and light-colored clothing to reduce skin exposure during peak mosquito activity times (dawn and dusk).
- Eliminate Breeding Grounds: Remove standing water around your home to reduce mosquito populations. This includes checking flower pots, bird baths, and clogged gutters. DIY mosquito control using sanitation can eliminate breeding grounds.
- Create a Mosquito-Free Zone: Use screens on windows and doors to keep mosquitoes out, and consider using mosquito netting around outdoor play areas.
- Have Pets Treated By A Veterinarian: Pet Doctors (AKA Veterinarians) understand the needs of your pet and can provide prevention from mosquito-borne illnesses like heartworm. Additionally, professional pest control can aid in heartworm prevention.

When to Seek Medical Attention
If you or your child experiences severe symptoms after a mosquito bite, such as difficulty breathing, swelling of the face or throat, or persistent pain, it’s essential to seek medical attention immediately. Allergic reactions can escalate quickly, and understanding when to act can be life-saving. Several mosquitoes bite humans and it can be helpful to know which may be present on your property.
Conclusion
Mosquito bites can be such a hassle, especially during the warmer months here in Kentucky. For kids, the irritation from these bites can sometimes lead to allergic reactions, which can be concerning for parents. Fortunately, these steps can minimize the risks and help our families enjoy outdoor fun without worry.
