He was bit three times (the doc found the bite marks), and the reaction was so bad that the doctor came out to tell his parents they'd better call next of kin - he was going to die. His blood pressure was so low, they had no idea how he ended up surviving when he started coming back around. He went to the allergist when we knew we were going someplace with fire ants again, and the allergist didn't even want to test him because of his near-death experience last time. Instead, he prescribed the epipen and said to be very cautious.
The whole incident happened when he was a very small child, so there is some hope he outgrew the allergy (according to the doc). However, we're not banking on it, and they wouldn't even test his allergy this time, even with 25 years since the last bites. My hope is that we won't have a problem at all - I will make certain we don't sit on or near planters, that we look at handrails before touching them, keep out of the underbrush, don't sit on grass, etc. I'm so glad to have all of these tips - and to be reminded that Disney has a quick response team. I think even if he's bitten, if I can use the epipen and Disney can get him to the hospital, we'll still be ok.
Also a good reminder that there are just regular old red ants. Boy, I'm going to be a nervous wreck by the time we get there!!!
