A dry powder supply with a duster included

Harris Diatomaceous Earth Crawling Insect Killer is a 4 lb bag of dry powder with a powder duster included inside. The format suits gardeners who want a 4 lb supply for careful, label-led placement around listed crawling-insect areas.

The included duster turns the bag into a controlled routine. Thin puffs stay visible, direct cleanly, and keep the area tidy near edges and tucked spaces.

Read the label before every placement

This is a pest product, so the label matters. Read the product directions before use, especially around edible crops, pets, wildlife areas, indoor surfaces, and water routes. The label should guide where the powder belongs and how the area should be handled afterward.

Dry placement is the heart of the routine. Powder that stays dry remains visible, and the duster helps keep the line thin.

Store it away from watering gear

The bag belongs in a dry shelf zone, separate from watering cans, sprayers, and rinse tubs. A sealed bin or dry plant-care shelf keeps the duster, label, gloves, and notes together.

During use, a light hand helps. Heavy piles create mess, and thin placement keeps the area readable on the next garden walk.
