Roaches are everywhere and depending on where you live you could have one or more of a variety of roaches right outside your door. Common species found around homes include American, Brown Banded, Asian and Smoky Brown cockroaches. Once any variety has established its presence in your yard or lawn, it is only a matter of time before they find their way inside your home.
Exclusion

Step 1
Remove the things that pests require, such as food, shelter and water. This is what pest control professionals refer to as exclusion. It is the best way to live pest-free without having to resort to using pesticide controls.

Step 2
Clear away any and all forms of clutter that provide shelter, including raking and removing excess grass clippings and leaves, storing firewood off the ground away from your home, and cutting back encroaching wooded areas.
Step 3
Remove water sources by repairing any leaks, filling areas that hold rain water, ensuring that gutters are kept clear of debris, and limiting watering your lawn to the morning so that it has time during the day to dry.
Treatment Options
Step 1
Spreading diatomaceous earth on your lawn is a non-toxic way to kill roaches. Made from fossilized microscopic shells that are ground into a powder, it works by penetrating an insect's body; it dries them out, yet it is harmless to people and animals. It is available on the Dirtworks link below.
Step 2
Use a pest control duster or a power duster to lightly dust your yard with diatomaceous earth during dry conditions because moisture limits its effectiveness. Spread it throughout your yard, particularly near areas where roaches can hide, such as around shrubbery, trees and areas with dense foliage or higher grass.
Step 3
Spread a granular insecticide on your lawn using either a push spreader or the handheld type. Unlike spray insecticide, which breaks down quickly in sunlight and rain, granular insecticide is activated by water and will last significantly longer. They are available at most home centers, such as Lowe's and Home Depot.
