How long does the talcum in interceptors remain effective? Had traps for a year and seeing no bugs in traps. Is this because no bugs are attempting to access an active bed or because the talc is old?
Talcum powder doesn’t move once it’s applied like it had been from the manufacturer - you would only need to reapply the powder if the old powder had been wiped or washed away.
Newer ClimbUps actually don’t come with talcum powder anymore. It was found in testing that the material is already too slick for any bed bugs to climb and escape from.
