Summer is a wonderful time to be outside – a time to play golf, to attend summer camp, to hike in parks, and to garden at home.

Unfortunately, summer is also a time for Hymenoptra stings (honey bees, wasps, yellow jackets, and hornets). Luckily, there are allergy treatment options available to help take the sting out ... literally!

Our allergy office is located in Creve Coeur. Come see us for a quick and convenient treatment option for insect stings. tinyurl.com/bdf29v68

Signature Allergy & Immunology is committed to the diagnosis, treatment, and management of asthma and allergy conditions.

Insect stings, including bee and wasp stings, are often overlooked and ignored until a severe reaction occurs. Testing is available that can help determine the severity of the reaction, and appropriate treatment can be discussed.

If you experience any summer stings, come see us for an evaluation: tinyurl.com/s5b9f2m8
