just a tip...

It has been sometime since I learned how to kill roaches without using any of those harmful insect sprays. The discovery came while I was washing dishes using detergent bar soap instead of liquid dish washing soap. A cockroach came out from a crevice on the kitchen wall and approached the sink rather fearlessly. It irked me a bit so I squeezed the sponge I was holding and gave the cockroach a sudsy bath. The roach performed a break dance at once and within a few minutes was dead. From that day on, I have a plant sprayer full of sudsy water ready for intrepid crawling insects.
