Cricket eggs need a warm, humid environment to hatch. They are usually incubated in soil or a substrate like vermiculite. The ideal temperature range for hatching is between 25 and 30 degrees Celsius, with relative humidity around 75%. As the eggs develop, they require more moisture in order to properly form and emerge from the eggshells. A container such as an aquarium can be used to keep the environment moist enough for successful hatching of cricket eggs. Additionally, once hatched, crickets will also need appropriate food sources (such as fresh vegetables) and calcium supplements (like crushed eggshells) in order for them to survive long-term.
