Anti-venom is given in severe cases and is available for only few species in the USA and Australia.
Burmese widow spiders generally lie in undisturbed areas and do not bite people unless disturbed.
They live in tangled webs and do not leave their web unless disturbed.
If these spiders bite anyone accidentally, necessary medications should be administered in a nearby hospital.
Nonetheless, there has been no record of human death from the bite of Burmese spider widow in Manipur.
As such, one need not panic or kill these spiders when they are sighted.
