Brief Answer:
Seems to be an allergic reaction.

Detailed Answer:
I read carefully your query and understand your concern.

It seems to be an allergic reaction.Since these red itchy dots appear only in his legs and arms (probably in the exposed area) something is causing this allergic reaction to him.

In my opinion there are 2 options:
1) Your son is allergic to something (tree,flower etc) in your outside environment
2) He is allergic to this bug repellent you spray him.

First thing to do is don't spray him when he goes outside and if the red itchy dots still appear then it is clear that bug repellent isn't the problem.

You can use an antihistaminic like Benadryl to relieve the symptoms.

I suggest to consult an allergist.Your son need to do allergy tests to identify the environmental agent which is causing this allergic reaction.
Once identified it,he should avoid the contact with it.

Hope my answer has helped.
Let me know if you have any further question or doubt to clarify.I will be happy to assist you further.

I'm a 62 year old healthy male and have a tested allergy to wheat even though I can eat wheat products daily without any ill effects. I have regular allergic attacks lasting fom 24hours to 3-4 days. My IgE levels have been tested on a number of occasions recently and show levels between 600 and 7000+ Ul/ml as opposed to a normal range of 0-100. How can i reduce my levels to a normal range?

Hi... I have had very swollen and droopy eyelids for several months and have had blood work done and allergy tests and everything is negative. I had botox about a year and a half ago and did get droppy eyelids but it went away. I wake up sometimes with it so severe that it looks as if someone has hit me!! I don't know if this could be caused by something more serious. I look as if I've aged 10 years in a few months!
