This phenomenon is called a cross-reaction. Cross-reaction with honeybee venomīecause bumblebee and honeybee venom contain similar albumen structures, some people are sensitive to bumblebees as well as to honeybees. that an allergic person will have more serious reaction with every new sting. Allergic reactions have the tendency to become more serious by repetition i.e. A general reaction manifests within 30 minutes after the sting. In serious cases, the heart and vascular system can also react: drop in blood pressure, loss of consciousness and anaphylaxis shock may occur. The respiratory system can also react the allergic person could feel a tickle in the throat with a cough reaction, or tightness in the chest and squeezed throat with difficulty in breathing as a consequence. vomiting and diarrhoea), and/or dizziness, abundant sweating and cold shakes. It is possible that these symptoms can be accompanied by unexpected intestinal complaints (e.g. The symptoms are nettle rash with itching, and sometimes swelling of the face and neck. Generalized allergic reactions (“anaphylaxis”) do not occur frequently and are characterized by the appearance of symptoms on body parts other than the one where a person was stung. Local reactions which are getting bigger can sometimes precede a generalized allergic reaction. Sometimes, even an entire limb can be affected in the reaction. The chance on an allergic reaction to the first sting is usually very small because no antibodies are present before the first sting.Īn allergic reaction can manifest through a big to very big local reaction. People who are “positive” for the presence of IgE antibodies can show an allergic reaction to the next bumblebee sting. The presence of these antibodies can be determined by a blood analysis. Allergic reactions to a bumblebee stingįor some people, the body reacts to the bumblebee venom through the production of IgE antibodies against albumen structures in the venom. A sting in the mouth or throat can be dangerous because of the risk of suffocation. Normally, the local reactions disappear quickly but can last for a couple of days in some cases. Sometimes, the swelling is really pronounced, especially on parts of the body with looser skin, such as the eyelids. Most people have a local reaction with painful swelling, redness and itching around the place of the sting. Local reactions to a bumblebee stingīumblebee venom, like in wasp and honeybee venom, contains certain substances that have a direct effect on the blood vessels in the skin. Contrary to a honeybee sting, the bumblebee sting has no barbs, which means that a bumblebee can pull back its sting without the sting detaching from its abdomen, thus a bumblebee can sting several times.įor most people, a bumblebee sting will only cause local swelling, but can cause an allergic reaction in some cases. Only female bumblebees (queens and workers) have a sting male bumblebees (drones) do not. When a bumblebee stings, it injects a venom into its victim. In general, bumblebees are peaceful insects and will only sting when they feel cornered or when their hive is disturbed.
