How long after exposure to Cyonara 9.7 will a bed bed die?

I bought Cyonara 9.7 to help treat bedbugs, I also got dust and growth regulator, I was wondering if bedbugs die instantly or is it a delayed process after they are sprayed with Cyonara?


Cyonara is not an instant knockdown insecticide. It could take anywhere from a few minutes to several hours for bed bugs that contact the direct spray or treated areas to die, depending on the size and health of the insect and how much active ingredient they contact. Keep in mind that you should plan on doing follow-up treatments for bed bugs until you have had 30 days with no signs of bed bug activity. We have more information and treatment tips in our Bed Bug Treatment Guide online here.
