Bob writes,

How often should Cyonara 9.7 be applied?

I sprayed around the perimeter of the house and in the boiler room mostly for crickets, but also for spiders and the infrequent American cockroach.


Cyonara is formulated to last up to 90 days, however for optimum results we recommend you apply at least every 45 days.  Most liquid insecticides will last 60 - 90 days inside a home, but when you apply them outside and they are exposed to UV light, they breakdown much quicker and typically may only last about 30 days.
