Bro listen to me and listen really Good,there is a pinkish powder that comes in a sachet and goes by the name Dress Force,empty the satchet into a bottle, fill the bottle with a satchet of pure water and shake vigorously,sprinkle it around all the affected areas where the bedbugs are hiding.make sure all ur foods are covered properly and wash ur hands thoroughly. the beauty of it is that it only cost 200 naira and it doesn't smell or choke. I tried it three months ago when all other insecticide had failed me. Use this bro and thank me later.
