Roaches are increasingly recognised as a valuable live food source for insectivorous pets, including reptiles, amphibians, and certain birds. Their high nutritional value, ease of breeding, and relatively low maintenance make them an excellent choice for pet owners. This paper explores various types of roaches commonly used as feeder insects, detailing their nutritional benefits, breeding requirements, and suitability for different pets.
Introduction
Feeder insects are a crucial component of the diet for many insectivorous pets. Among these, roaches have gained popularity due to their high protein content, ease of care, and ability to stimulate natural hunting behaviours. This paper examines several species of roaches that are commonly used as live food, providing insights into their characteristics and benefits.
