Acting quickly can reduce your risk of a serious reaction.
First remove stinging insects or their stingers. In most cases you can simply brush the insect away. You may need to pull fire ants off -- be sure to check for multiple ants and get rid of all of them.
Putzing in the garden is nothing less than therapy. It's even good exercise,
if you exert enough effort. But the sneezing and stuffy-headed feeling that
lingers afterwards -- that's the downside of gardening with allergies.
