The methods of raising earthworms are as follows:

1. Breeding box selection: Choose a container suitable for breeding earthworms. You can use plastic boxes, wooden boxes or other suitable containers. Make sure the container has ventilation holes to allow air circulation.

2. Feed preparation: Ground beetles mainly feed on organic waste, such as vegetable peels, leftovers, coffee grounds, etc. Make sure the feed has no added salt or harmful chemicals.

3. Substrate preparation: Soil beetles need to live and reproduce in a suitable substrate. You can use piles of rotten leaves, soil, wood chips, etc. as substrates. Make sure the substrate is moist but not too wet.
