Dubia problem

[timscrape]

I'm having a problem with my dubias. They are climbing the walls of their container. They even cross my Vaseline safety barrier around the top. I though that they couldn't climb walls at all. And I really thought the Vaseline would catch any talented ones. What do I do?

It depends on the type of container, some will have a very fine grit on the inside and outside. Try lining the inside with clear packaging tape or vasaline, it will be too slippery for the roaches to climb. I find it really bizarre that dubias were climbing the sides of the container. Are you sure they're dubias?

Consider getting a new plastic container, and ensure that is is completely SMOOTH. As Ryan said, some of the plastic bins (usually the heavy duty types) have just the slightest bit of texture that the smallest nymphs can take advantage of. I had a tougher rubbermaid bin at one point and was finding baby dubia everywhere in the house until I realized they were able to climb out. Look for plastic bins that have reflective sheen to them, and feel them out to ensure they are totally and completely smooth... Sterilite usually does a good job. I have a brand from Home Depot or Lowes that is a lightish blue plastic which works well for most of my colonies (I want to say the brand is HDX or something, I honestly can't remember).
