'Skeeter Syndrome': Is My Kid's Bug Bite Infected?

When to see your pediatrician after an insect bite, including mosquitoes and ticks

School’s out for summer! It’s time for playing at the park, swimming and catching lightning bugs. Unfortunately, it’s also the time when I see many office visits related to insect bites and their complications. It seems like no matter how hard I try to prevent them, my kids always end up with at least a few itchy bug bites. Parents are often concerned about whether or not a big red swollen spot is infected and if it needs antibiotics.

Most people develop some redness and itching after a mosquito bite. Unfortunately, some children will have what’s known as a large local reaction, or “Skeeter syndrome.” This happens due to an allergy to mosquito saliva. These patients develop redness and swelling within hours of a mosquito bite. The swelling can be very large (like an entire arm or leg) and typically worsens over 1-2 days. In the worse reactions there can be bruising and even blistering!

It’s not always easy even for your doctor to tell the difference between “Skeeter syndrome” and a skin infection. One of the big differences is the timeline. Skin infections usually happen several days after a bite or an injury, but “Skeeter syndrome” usually starts within a few hours of a bite. Most often children with a large local reaction will complain about intense itching. Only in the more severe cases are pain and fever seen with allergy. It’s not common, but some even develop severe allergic reactions to mosquito bites that lead to difficulty breathing.

Large local reactions are best treated with oral antihistamines (Benadryl or Zyrtec) and topical over-the-counter steroid cream (hydrocortisone 1 percent). Fingernails need to be trimmed very short, because scratching causes local skin damage that can become infected. Cold compresses several times a day help alleviate some of the discomfort. In patients who have a history of this type of reaction, I recommend daily antihistamines such as Zyrtec during the time of the year when bites are difficult to avoid. This doesn’t totally prevent the reaction, but can help keep the swelling from being as extreme. I don’t recommend topical antihistamines (Benadryl cream) because some people develop a contact allergy that actually worsens the problem

So, when should you come to the doctor? 

Any child with significant eyelid swelling or swelling that is limiting activity or skin blistering deserves an office visit because they require further evaluation and sometimes even need oral steroids or more potent prescription topical steroids. Red/swollen/hot areas of skin that are associated with pain or fever should also be examined to rule out a bacterial infection.

Tick bites don’t usually cause itching like mosquitos, but are more of a concern due to infections they can transmit. Ticks are predicted to be more prevalent this summer due to the winter being relatively warm. Ticks can transmit several infections with Lyme being one that is often discussed.

If you find a tick on your child it should be removed with tweezers by grasping the tick as close to the skin as possible and pulling straight up. Different types of ticks spread different infections. For example, infected deer ticks can spread Lyme after being attached for 36 hours or longer. Certain areas of the country have a much higher rate of local tick infection than others. Texas is not a part of that area, but cases of Lyme do occur every year.

It is best if children bathe after coming in from playing outside to wash off ticks prior to attachment. It’s a good idea to look in hidden areas such as behind the ears and on the scalp. Remove ticks if you find them and watch for a rash. Certainly, a rash that looks like a bull’s eye or a target (erythema migrans) is concerning for Lyme infection and needs to be seen for further testing.

Insect bite avoidance is important (and hard)! The large local reactions are definitely very uncomfortable, but infections transmitted by mosquitos such as West Nile or Lyme from ticks are potentially very dangerous. Using DEET containing insect repellant and wearing long sleeves during peak mosquito times are helpful.

As always, see your pediatrician if you are worried about a bite or rash and we are happy to help.
