A stinging insect allergy is an allergic reaction to venom from insects such as honeybees, wasps, hornets, yellow jackets, or fire ants. Unlike a normal sting reaction—which causes mild pain, redness, and swelling—an allergic reaction can trigger more serious symptoms throughout the body. Some people experience only local swelling at the sting site, while others may have a systemic (whole-body) reaction.

At Denver Allergy & Asthma Associates, we often see patients who are unsure whether their sting reaction was truly allergic or simply a normal response. Our specialists can help clarify your risk and develop a personalised safety plan.

Who is this service for?

This service is for anyone who has experienced an allergic reaction to a stinging insect sting, or who suspects they may be allergic. You may benefit from evaluation if you have:

Had swelling beyond the sting site after an insect sting
Experienced difficulty breathing, throat tightness, or dizziness after a sting
A family history of severe insect sting allergies
Outdoor work or hobbies that increase sting risk
Anxiety about future stings affecting your quality of life

What to expect during your visit

During your appointment, your allergist will review your sting history in detail, including what insect stung you, where, and what symptoms developed. This conversation helps us understand your specific risk level.

We may perform skin testing (a small prick test using insect venom extracts) to confirm which insects you are allergic to. Blood tests may also be used to measure your sensitivity. These tests are quick, safe, and help guide your treatment plan.

Personalised management planning

Based on your test results and medical history, your specialist will discuss options with you, which may include emergency action plans, prescription medications, and whether immunotherapy (allergy shots) is appropriate for your situation.

Treatment and management options

Treatment depends on the severity of your allergy and your lifestyle. Options may include:

Prescription epinephrine auto-injector (EpiPen) for emergency use
Antihistamines and corticosteroids to manage mild reactions
Venom immunotherapy (VIT)—a series of injections that gradually desensitise your immune system to insect venom
Lifestyle and environmental strategies to reduce sting risk
Education on recognising early warning signs and when to seek emergency care

Venom immunotherapy is highly effective and can reduce your risk of a severe reaction by up to 98% in patients who complete the full course. Your allergist will assess whether this treatment is right for you.

Understanding your stinging insect allergy Q & A

A true allergic reaction goes beyond normal sting pain and redness. If you experienced swelling beyond the sting site, hives, difficulty breathing, or throat tightness after a sting, you may have an allergy. Our specialists can perform skin and blood tests to confirm your sensitivity. We recommend scheduling an evaluation if you're unsure.

Yes, venom immunotherapy (VIT) is a well-established, safe treatment when administered by experienced allergists. It involves gradually increasing doses of insect venom to desensitise your immune system. Studies show it can reduce your risk of a severe reaction by up to 98%. Your allergist will discuss whether VIT is appropriate for your specific situation.

If you experience symptoms like swelling, difficulty breathing, or throat tightness, use your epinephrine auto-injector immediately if prescribed, and call 911. Even if symptoms improve, seek emergency medical care. Your allergist will provide detailed emergency action instructions and ensure you have the right medications on hand.

While you cannot eliminate all risk, you can reduce it by avoiding bright colours and floral patterns outdoors, wearing closed-toe shoes, avoiding perfumes and scented products, and staying away from nests and hives. Your allergist can provide additional prevention strategies tailored to your lifestyle and risk factors.

Venom immunotherapy typically involves a build-up phase (3-6 months) where you receive injections at increasing doses, followed by a maintenance phase lasting 3-5 years. During maintenance, you receive injections every 4-6 weeks. Your allergist will explain the full timeline and what to expect at each stage.

This depends on your allergy severity and whether you pursue venom immunotherapy. If you complete VIT successfully, your risk of severe reaction decreases significantly, and your allergist may eventually recommend discontinuing the auto-injector. Your specialist will guide this decision based on your individual circumstances.
