Background & objectives: The common bedbug Cimex lectularius Linnaeus 1758 (Hemiptera: Cimicidae) is a globally re-emerging pest of serious public health concern. We investigated bedbug infestation in randomly selected apartments in Gbajimba community in Guma Local Government area in Benue state, Nigeria.
Methods: Beddings and furniture (bed frames, pillows, mattresses, cushion chairs, mats, mosquito nets and bamboo beds) were thoroughly inspected for bedbug infestation using the hand-picking technique. Data were analysed using chi- square analysis for differences in the infestation levels in harbourages and sampling locations.
Results: Only 16% of the apartments investigated showed no evidence of bedbug infestation as egg cases and faecal marks were sighted in 62.2% of apartments surveyed. The highest infestation rate was observed in Angwan Jukun area and infestation here was higher compared to other study locations within the town though the difference was not statistically significant (x2 = 7.92, df = 6, p >0.05). Bamboo beds harboured the highest number of bedbugs collected, accounting for 35.8%, while other harbourages like iron bed frames and sleeping mats had 23 and 22.7% infestation rates respectively. The infestation rates in these household items were significantly higher than other items inspected (x2 = 11.8, df = 4, p > 0.05).
Interpretation & conclusion: This study demonstrates the urgent need for identification of evidences of infestation and bedbug management involving community participation in inspection, detection and education, including physical removal and exclusion as well as pesticide application.
