Can a spider lay eggs in a human body?my friend said a spider laid eggs in his arm before

for everyone that says this is only a legend... 

yes spiders can lay eggs inside a body.. if they can get inside..

more or less all insects hachin time is determend by tha heat around tha eggs,, and human/animals are optimal heatsource for this.

 i work as a bucher.. and iv seen meny insect Eggs youst insde of tha animals skin.. but most times these are eggs from Flyes.
