Insect Allergy

What Is an Insect Allergy?

An insect allergy occurs when the body overreacts to venom or saliva from insect stings or bites. While these allergies can sometimes cause severe reactions, understanding them allows you to take control and live confidently.


To diagnose an insect allergy, your doctor will review your medical history and perform targeted tests to identify the specific trigger. If confirmed, your specialist will create a personalized treatment plan, which may include:


  • Guidance on avoiding insect stings or bites.
  • Emergency medications like epinephrine to manage reactions.
  • Venom immunotherapy to reduce the risk of severe allergic responses over time.


With the right care, you can effectively manage insect allergies and minimize their impact on your daily life.

Symptoms of Insect Allergies

Insect allergies can trigger a wide range of symptoms, and it's essential to recognize them early for effective management. Common reactions to insect stings may include:


  • Localized Reactions 
  • Symptoms: Redness, swelling, and pain at the sting site.
  • Severity: Usually mild and self-resolving.


  • Systemic Reactions 
  • Symptoms: Hives, itching, or swelling extending beyond the sting area.
  • Severity: Can be more severe but not life-threatening in most cases.


  • Anaphylaxis
  • Symptoms: Difficulty breathing, throat swelling, dizziness, and rapid heartbeat.
  • Action: Call 911 immediately if these symptoms occur.

What are the Causes of Insect Allergies?

Insect allergies are caused by an overreaction of the immune system to venom or saliva injected during stings or bites. San Antonio’s warm climate and active outdoor lifestyle increase the likelihood of encountering common allergy-triggering insects, such as:


  • Bees
  • Wasps
  • Hornets
  • Fire ants


Allergic reactions may range from mild discomfort to severe life-threatening responses.

Insect Allergy Treatment and Diagnosis

Diagnosing an insect allergy begins with a review of your medical history, including any previous reactions to insect stings or bites. Your doctor may perform skin tests where small amounts of venom from different insects are applied to your skin to assess allergic reactions. 


In some cases, blood tests may also be conducted to detect specific antibodies related to insect venom. Combining these tests helps identify the exact allergen, enabling your doctor to develop an effective treatment plan tailored to your needs.


How is Anaphylaxis Treated?

For immediate relief, patients are offered the following insect bites and stings treatments:


Antihistamines :

These medications help relieve itching, hives, and swelling. Over-the-counter options, such as diphenhydramine (Benadryl), can be effective for mild reactions.


Corticosteroids :

Topical corticosteroids may be used to address the swelling or inflammation at the sting site. For more significant reactions, a healthcare professional might prescribe oral corticosteroids.


Epinephrine :

For patients at risk of anaphylaxis reaction, the specialist will recommend bringing an epinephrine auto-injector around. This medication can quickly counteract severe allergic reactions, and our compassionate team can help you learn how to use it and assist you with insect allergy symptoms!


For a more proactive approach, your specialist may also recommend these treatments to build tolerance and prevent future reactions: 


Avoidance Strategies :

Learning to identify and avoid potential triggers is vital. This may include staying away from certain areas during peak insect activity or wearing protective clothing outdoors.


Venom Immunotherapy :

This treatment involves regular injections of small amounts of venom to gradually desensitize the immune system. It can significantly minimize the likelihood of severe reactions from future stings and is particularly effective for those with a confirmed insect sting allergy.

Insect Allergy FAQs

  • Can you develop an insect allergy as an adult?

    Yes. Many people can become allergic to insect stings later in life. Repeated stings over time can trigger an insect allergic reaction, even if you’ve never had one before.

  • What should I always carry if I know I’m allergic to insect stings?

    If you know you have an insect allergy, always bring an epinephrine auto-injector (EpiPen). This life-saving medication can quickly treat severe insect allergic symptoms, buying you crucial time until you can get emergency care.

  • How can I keep my child safe if they’re allergic to insect stings?

    If your child has an insect allergy, teach them how to avoid stings, such as wearing closed-toe shoes outside and staying calm around bees or wasps, rather than swatting at them. Ensure they always carry an EpiPen and inform any teacher or caregiver about their allergy and the necessary actions to take in case of an emergency.

  • Do insect allergies run in families?

    While an insect allergy is usually not hereditary, having a family history of other allergies can raise the chances of developing an allergic reaction to insect stings.

  • What’s the best way to avoid getting stung?

    To lower your chances of getting stung and avoid an insect allergy reaction, wear light-colored clothes, avoid strong perfumes, cover food when eating outdoors, and stay calm if there’s a bee or wasp nearby.
