If you're willing to make the drive, Pets-A-Plenty up in Hockley; North 290, has tons of reptile supplies. I try to make the drive all the way from Sugar Land because it's the only place in Houston like it. I searched all over Westheimer, more sad stories than good unfortunately, and they're about as close as it gets. Give them a shout to see what they have. In the mean time, West Coast Roaches is AMAZING! Also, Small Pet Feeders has just about everything you could look for at pretty good prices when you add it all up. I think they're based out of Georgia. Mulberry Farms has an awesome deal on 1000 superworms last I checked.
