I found it living INSIDE my cactus. this guy was roughly 2.7 to 3 inches long!! can anyone id it? how did it get inside? I saw NO damage from the outside... I only found out because I was doing a random "squish test", and it failed. that cactus is now gone, but it was in a window box with 4 other cacti. Do I need to cut them all open too? Simply change dirt and re-pot? PLEASE, all help will be welcome!!
