Marlene from Charles Town writes,

How long does an application last?

Once I apply this product, when does it need to be re-applied? In other words, how long is an application effective before it needs to be re-applied??


Maggies Farm Spider and Insect Dust can last for many years in wall voids depending on how often it is disturbed. We would recommend using the dust every 7 months or so to continue to combat insects.
