If you are concerned with applying DE in smaller areas like nooks and crannies, we recommend that you use one of the applicators we have on offer. The JT Eaton Duster is an exceptional tool for getting into small areas like along door sills and baseboards; in hard to reach corners and cupboards; and even behind faceplates of switches and sockets.
Fill the applicator and shake.
Point the nozzle at the desired area or location and spray.
Repeat after vacuuming.
