Review on Fluker Labs Repta-Bark: The Ultimate All Natural Bedding Solution for Reptiles by Darryel Tokarczyk

Too much substrate leaves a lot of residue in the water bowl. These are good sized pieces of bark, up to half an inch. I haven't experienced any problems with bugs as I've seen reports with other brands. I also put some peat moss on top after soaking in water to keep moisture needed at different times of the year. I also recently changed the landscape to use large flat rocks around the water/swimming bowl to keep the substrate a little further from the water and less likely to make a mess.
