Probably because the itch, is actually an allergic reaction - so histamines are released, causing a reaction even in small areas previously affected.

What has worked for me quite well, is to dab white vinegar on the bites, and the itch goes away immediately.

Avon's Skin So Soft oil still works wonderfully for me to keep them at bay.

May they not be hungry today!
