Zomites were a species of "intelligent insects" native to the planet Skaro. They resembled blue spheres with four stub-like limbs.
When the First Doctor, Ian Chesterton and Barbara Wright landed on Skaro, the insects swarmed the trio from holes in the ground and attacked them. Daleks then arrived at the scene and attacked the Zomites, easily destroying them with their gunsticks. The Daleks stated that the Zomites were their pests and because the three assisted their extermination, the Daleks allowed them to leave unharmed. (COMIC: The Daleks Destroy the Zomites)
