2. Flying ants are not necessarily toxic after being bitten. Flying ants are just an ordinary kind of insects, and the saliva of some flying ants has obvious allergic nature. Therefore, some people may have serious allergic reaction after being bitten, but it is not necessarily a toxic reaction. Because the saliva of flying ants, in many cases, has similarities with the saliva of common ants, the toxicity is not too great. However, due to individual differences, some people may have allergic reactions, resulting in redness and swelling, or even generalized discomfort, such as hives, or even serious symptoms such as choking, vomiting, diarrhea, and so on. If these serious symptoms occur, you need to go to the hospital in time.
