You can kill cockroaches with the help of diatomaceous earth. It eats through the exoskeleton of the pest killing it within 24 hours. Often we see the roaches getting dehydrated and coming out after it is applied. But this may not eliminate the entire colony.
A particularly stubborn or severe infestation could require this level of treatment. It is possible to completely get rid of roaches in your home with the right type of treatment but they will not stay away forever. Once you eradicate the current infestation you need to stay proactive about keeping them away.
Clean Up. Remember: roaches need three things to survive – food, water, and shelter. ...
Use Sticky Traps. Sticky traps aren't only for indoor use – you can place them outdoors, too. ...
Place Bait. To decrease the number of roaches entering your home, kill them with bait before they get inside. ...
Spray Pesticide.
