Tree roaches do not bite or spray. But they are huge, sometimes airborne and unpleasant to have around. However, unlike their smaller relatives they do not live or breed in your home but wander in from the outside. Unfortunately this means that they are also harder to kill. Because they live out of doors and have no central nest, it is nearly impossible to kill the entire population. However, you can kill the tree roaches that visit your home and keep new ones from coming back.
Seal the perimeter. Tree roaches find their way into your home through cracks, gaps and other openings. Make sure that all doors and windows are properly sealed and check your attic and basement for any possible points of entry.
Stop luring tree roaches to your home. Tree roaches are attracted to food, water and light. Make sure that all food, especially dog food, is carefully sealed and put away. Any standing water, even small amounts, should be dried. If there is a wood pile near your home, remove it. It is likely a food source and breeding ground for local tree roaches. Finally, turn of outdoor lights at night in the summer when tree roaches are the most active. They attract male roaches.
Kill any tree roaches that you find in your home.
Spray possible entry points around your home with an outdoor insecticide. Also spray around the foundation of any firewood piles.
Call a professional exterminator if the tree roach infestation is severe or unresponsive to the above methods.
