Pests can bite us, spoil food material, cause health problems, etc. Therefore, to live a safe and healthy life, pest control is necessary.
If you do pest control once and expect them not to enter your home again, then you are wrong. When the pest control effect vanishes, they enter again. Therefore, you should do pest inspections regularly.
DIYs provide short-term relief from pests. They are also not safe to use without professional guidelines. Thus, DIYs are not as effective as professional treatment services.
