  1. I have used peppermint oil and other essential oils to kill roaches. I mix it into Thieves cleaner and spot spray them on sight; almost immediately they flop over and die. However, it does not rid my oven of the infestation and because the spray dries quickly, it does not protect surfaces for very long. I’m trying a mixture of date syrup and baking soda, with a dish of water nearby.

    1. It depends on how roaches escape and the condition of their legs. When glue traps get roaches, you can use a roach spray to kill them or if the glue trap gets a lot of roaches, then you can simply burn it. So the main idea is to kill these roaches before they escape from your glue traps. However, glue traps are not the best way to deal with them.
