Lybius bidentatus eats fruits and insects. They search in the foliage for food, usually staying below ten meters. Of insects, they eat beetles, termites, ants, and Hemiptera, which they find in the tree bark or in clusters of leaves. Often a double-toothed barbet will capture winged ants or termites while in flight. They also eat fruits: figs, papayas, avocados, and the fruits of the umbrella tree Musanga and of Solanum. Double-toothed barbets will eat the seeds of some fruits.
These barbets can be found in pairs or small family groups with helpers; lone double-toothed barbets are rare. Their territories are large.
Double-toothed barbets roost communally, as all the barbets in a group roost in the same hole. Nests are made by excavating a tree, often rotting, at above two meters. Both barbets in a pair will dig out the nesting hole, and both will defend it. The entrance the nest is circular, five or more centimeters across. Some nests have an entrance tunnel. At maximum, a nest is 46 centimeters deep.
When a male double-toothed barbet displays for a female, he swings his tail and body around. He also shows the patches of white feathers on his flank. The courting birds will preen each other and go back and forth. The male will sometimes tap a nest entrance to attract the female toward it.
Breeding happens year-round. The female lays between two and four eggs, which are white. Incubation of the eggs lasts for about 13 days. At first, adult birds feed the hatchlings insects, then later mostly fruit. The hatchlings' parents and the helpers remove feces from the nest. After 37 to 39 days, the hatchlings fledge.
