Venom therapy involves building up a tolerance to identified allergens
in insect venoms through gradually increasing doses of the specific
venom causing the allergy. The therapy is delivered by
injection and once tolerance is achieved, it must be maintained through
periodic (usually monthly) injections. Because of the frequency and
expense of repeated injections, most people will probably not find this
option feasible unless they work regularly around stinging insects.
I hope this information is helpful.
