The increased cost of protein source in compounding fish feed has prompted scientists to research for easily accessible protein source that will partially or completely replace fish in the diet of fish. Thus this study was aimed at using garlic powder as supplement in the diets of 3rd nymphal stages of Blattodea germanica and Supella longipalpa for antibacterial activities. Adult cockroaches with eggs were collected from indoor apartments within Lapai town, reared under laboratory conditions for ten (10) weeks and fed formulated diets during this period. At the end of the experimental period, cockroaches were sacrificed randomly for their bacterial population on the external body surface and in the gut. Isolates identified include; Escherichia coli, Klebsiella spp., Pseudomonas aeruginosa, Proteus spp., Bacillus spp., Staphylococcus aureus, Streptococcus spp., Salmonella spp. and Shigella spp. respectively. This study therefore supports the use of garlic as an effective antibacterial agent against strains of bacteria.
