what you could do ... if cover the soil with rocks, rocks heavy enough that they cant lift them. most nursery's sell rocks for this purpose, id get polished rocks so they dont eat them by breaking pieces off, that can be very dangerous.
try that and see if it works to keep the bugs out and id use some grapefruit seed extract when you water the plant, mixed into the water to keep it from getting moldy, which can also be a huge problem and make them sick.
http://www.vitaminshoppe.com/store/en/br...;ci_sku=NQ-2001id put about 30 drops in 1cup of water for that purpose.
you can also put about 2-3 drops in the water 3 days in a row then pure water 3 days in a row without it
this will help cleanse their system.
apple cider vinegar also works the same way, but different ratios, for the plant id 2 parts apple cider vinegar and 1 part water
in the drinking water id do 1 part ACV and 3 parts water. 3 days in a row then 3 days pure water, 3 days with ACV and 3 days pure water and so on ...
it must be apple cider vinegar not any other kind of vinegar.
