I have a child extremely allergic to insect bites. If he gets bt by one ant on his big toe his whole foot swells up.
He was 5 when we got our hognose.
We've had closed-mouth strikes for when my kids get too lazy and clean the enclosure without taking out the hoggie... it doesn't even startle them anymore. But, we've never had any bites. But then, my kids are very knowledgeable about their pets' moods.
