- During month 13 the walls and ceiling of the hut sprayed with p-methyl EC were covered with plastic sheeting. Between months 15 and 16 the treated walls of every hut were covered with plastic sheeting for one out of every two weeks. Data are grouped according to whether the walls were covered or uncovered. BFI = blood-feeding inhibition compared to untreated control.
