I know at some point everyone probably has a problem with bugs and now my time has come. I used a mixture of organic soil and cypress mulch, or what I thought was cypress mulch, and immedietly had a bug problem. They were small and darker colored had six legs and little intenae. But too small for my camera to get a picture. They mostly crowded his food dish so i tried to make sure there was no food left in there when Marlin was done eating. I never saw the bugs on him. I threw all that substrate out. I figured it was the mulch that actually wasn't cypress mulch like the people at the hardware said. So I just filled his enclosure with straight organic soil since he likes burrowing in it. I planted some seeds and have had everything set up for about a week and started noticing bugs again. They dont seem to bother him, but am I doomed with bugs if I keep this substrate? How do I find a bug free substrate?
