Yes, ticks are very common in temperate zones, especially on wooden beds, which can be scalded to death with boiling water. In the past, 223, 666, trichlorfon and dichlorvos were used to control bedbugs. Due to the discontinuation of 223 and 666, dichlorvos and trichlorfon were short-lived, and these organic chlorine and organophosphorus pesticides easily made brown sheds brittle and broken, which was not only unacceptable to the public, but also difficult to achieve the purpose of eliminating bedbugs. Therefore, these drugs are currently used.
