If I use live ladybugs indoors will they completely get rid of the spider mites. And if they do completely get rid of them then how do I keep the ladybugs alive if they have no more spider mites to feed on. I figure this would be the best most natural way to get rid of pests. Any help appreciated. also how many ladybugs do I need for an 8x8x12 room with about 12 plants?
i do believe you will need 2 for each plant unless they are small than about 1 per plant, lady bugs dont have a long life span anyway i think 4-8 weeks but not sure
