Do geckos like dead roaches

Most gecko species will only feed on live feeders. The reason for this is that the geckos need some sort of movement to stimulate their interest. I do not feel that a dead roach is going to capture the animals attention. There is a product made by fluckers i believe that is a battery operated mechanism that has what seems to be similar to a speaker on the top, that when activated it vibrates up and down. The dead feeders are then put onto this and they bounce up and down. I do not recommend feeding dead feeders as they do not carry the same nutritional value that live feeders would.
