What do you do if jumping beans won't hop?

If your jumping beans aren't hopping, it could be due to a few reasons. First, ensure they are kept in a warm environment, as they need heat to be active; temperatures around 70°F to 85°F (21°C to 29°C) are ideal. Also, check that the beans are not too dry; a slight increase in humidity can help. If they still don't move, it’s possible they are no longer viable, and you may need to consider replacing them.
