Can you hatch a praying mantis egg in winter using a heat lamp for 8 weeks in doors?

Yes, you can hatch a praying mantis egg case indoors during winter using a heat lamp. Praying mantis eggs typically require warmth and humidity to hatch, and a consistent temperature of around 70-80°F (21-27°C) can help facilitate this process. Ensure that the egg case is kept in a suitable container with adequate ventilation and moisture. After about 8 weeks, if conditions are optimal, the nymphs should emerge.
