the problem with this is usually when mealworms or superworms burrow they are going to pupate and turn into beatles, so they will not really be a whole lot of vibration from them once this is trigger. once the metamorphosis is complete they are beetles and go back above ground to procreate and end their life cycle. this is why I don't feed them to trapdoors they just don't trigger a response like crickets do.Are trapdoor spiders curious animal I was wondering what if you put the tall enclosed it was in in a mealworm bin on the mealworm,s food will it dig to the bottom of the cage to find out what is making the sound ageanst the cage
