The problems associated with insect bites are interesting because the medical literature is reap with those kinds of insects that cause tissue destruction, toxins throughout the body, and can really lead to life threatening injuries that require intensive care unit care. That is a bit of an extreme because more often, we see insects, flies, spiders that typically cause a localized reaction in the skin. Something like a little blister or a papule. Occasionally, those get the surrounding redness and the skin becomes infected. That is called cellulitis and requires the use of an antibiotic. There are spiders, like Black Widow's, that can cause more tissue damage, more systemic findings related to the toxin that gets into the child's system. Some of those do require an antidote or a special medication, to counteract the effects of a toxin. If a parent is really concerned about an insect bite or the surround area around that insect bite, they should seek medical care right away. If anything, they should be able to get instruction on how to care for the localized area. If by chance it happens to be one of the poisonous insects, the antidote can be given right away to prevent further destruction of tissue and other systemic problems.
