hi can any one give me advice on a bit of a problem that i have, some while ago i purchased some exo terra rock background to make my viv a bit more pleasing to the eye for ollie my 1 year old yemen, everything seemed fine but just lately the crickets have taken to eating this background at a amazing rate also the are breeding and getting out around the house, before anyone says "no cannot happen" over a month ago i purchased some "black" crickets a mistake i know now, ollie was quite happy in eating all of them or so i thought, last night i had to kill two of the buggers that were running up my living room wall.
