There's massive variation across insect species, relatively little research and no industrialisation on the scale of current farming. It's not useful to generalise all insects and all production techniques simply to "bugs are less efficient".
In a study of 236 edible species, protein content of dry matter ranged from 6% to 77%. [1]
And a study of a particular grasshopper found it had higher protein content than lamb, beef, pork, chicken, turkey and fish [2].
AFAIK it's very hard to keep them sterile, and a large volume of crickets may look like a lot but not produce much protein. If packed too densely, maybe they crush each other or otherwise die?

less efficient in what way? you could probably raise crickets in a smaller space and with less resources.
