I just want say I know nothing about scorpions. I obtained 4 scorpions from my sister that she found in her house. She did not want to throw them back outside because of fears of them coming back in the house or stinging their dogs outside. The environment around her house is Juniper and sagebrush common in Central Oregon High Desert. I have lived here since 1993 and this is the first time I have run across scorpions here, so I don't know how rare they are. So far they are living together large tank filled with native soil and rotted wood. From the internet I learned to feed them small crickets and give them water by a dish with damp cotton balls. Learned a lot from the scorpions. They really like to dig burrows. I cut some pine needles about less than an inch long just to see what they do with them. I was surprised they used them to reinforce their burrows or sometimes cover them up. I am not sure what kind of scorpions they are so I added photos.
I always have had plans to let them go once the weather was warm enough and insects plentiful again. I wanted to let them go close to where they were found. I do have crazy ideas to make use of them in my 8 by 6 garden surrounded by wire fencing to keep out animals. Just need some lawn edging to go deep enough in the soil and high enough to keep the scorpions in. I would create some livable area made of rock and wood in each corner of the garden. I am guessing if I am lucky they will stay there in the day and come out to feed on pests at night.
My other idea was creating a winter hardy cactus garden enclosed with lawn edging around 8 by 6 in size. Hopefully the cactus will be enough to keep animals out. Enough loose soil to burrow in and dead wood to hide under.
Any issues with my ideas? Like where I decide to let them go if I do that. If I do an outdoor enclosure, will it be big enough and what I need to attracts bugs they can eat. For example what plants would be good to attract prey they would like to eat.
