Depending on an individual's sensitivity, maggot exposure through direct skin contact can cause various reactions.  For those with no allergies or sensitivities towards insects such as flies or mosquitoes, coming into contact with a maggot should not result in an adverse reaction.  However, individuals who experience irritation from other biting insects could find that similar problems occur when near certain types of larvae. Generally, most people will feel a tingling sensation, but no further damage will follow.
