Bug traps can be hit or miss, unless you follow expert instructions and make your own.
in Charlotte, North Carolina, offer an easy stink bug trap, mosquito trap, and fruit fly trap that actually get the job done, and explain why they work. Omnipresent stink bugs, with their pungent coriander-like odor , can make a home uninhabitable. Ashcraft has a quick fix. Start by cutting off the top 2 inches of a two-liter bottle. Then invert and tape the neck to the opening so the top sits within the bottle. Drop a small battery-powered light into the container.
Connelly suggests a low-tech “ovitrap,” which uses standing water to lure, two common breeds. First, cut off the top of a two-liter plastic bottle, and spray-paint the outside a solid black. Then drill two 3/8-inch overflow holes below the brim. Cover them, and the top, with fine mesh. Secure a wet cloth around the brim and fill the trap with water. Eggs, laid on the fabric, will hatch, fall through the mesh, and grow too large to escape.For fruit flies, Connelly’s recommended trap is simple.
