Garden insect killer dusts are pesticides, so it’s important to use them carefully. Many home gardeners use them safely by following the label.

• Read the label first: Follow all directions, precautions, and reentry timing.
• Protect yourself: Wear gloves, long sleeves, and a dust mask or face covering to avoid breathing particles.
• Apply smart: Use on calm days, avoid creating clouds of dust, and keep people and pets away during application.
• Clean up: Wash hands and exposed skin after use; launder work clothes separately.
• Store safely: Keep the container tightly closed and out of reach of children and pets.

If accidental exposure occurs, follow the first-aid guidance on the label and consider contacting a medical professional for advice.

Coverage varies by product, but garden insect dusts typically list a range of leaf- and stem-feeding pests. Always check the specific label for the approved pest list and where it can be used.

• Commonly listed pests often include beetles, caterpillars, leafhoppers, aphids, earwigs, stink bugs, and squash bugs.
• Where it’s used: Many are labeled for use on ornamentals, shrubs, and certain garden plants; verify the exact plant types on the label.
• Match to your issue: Identify the pest first, then choose a product that names that pest.

For heavier infestations, combining treatments with good garden practices (like removing infested leaves and reducing plant stress) can help, but results may vary by conditions.

Use garden insect dusts exactly as directed on the product label for the plant and pest you’re treating.

1. Check the label: Confirm the plant is listed and note any use restrictions or intervals.
2. Apply lightly: Dust a thin, even layer on upper and lower leaf surfaces and around stems—avoid heavy piles.
3. Time it right: Apply on a calm day, ideally early or late when pollinators are less active.
4. Avoid blooms: Try not to dust open flowers to reduce exposure to beneficial insects.
5. Reapply only as directed: Some labels allow reapplication after rain or if pests return.

Keep people and pets out of treated areas until the label’s reentry timing is met.

Many garden insect dusts are designed for plant-feeding insects and may not be intended for stinging insects like wasps or hornets. Effectiveness depends on whether the product’s label specifically includes those pests and the permitted use sites.

• Check the label: Look for wasps, yellowjackets, or hornets on the pest list and follow any special directions.
• Use safely: Avoid disturbing active nests; that can increase sting risk.
• Consider alternatives: If the label doesn’t include stinging insects or nest treatments, a product labeled specifically for wasps/hornets or professional help may be more appropriate.

Always prioritize safety and follow all precautions on the product you choose.

Choose based on where the problem is and how you prefer to apply.

• Dust: Suited for targeted, above-ground plant pests. It’s applied as a light coating on listed leaves and stems for spot treatments.
• Sulfur dust: Combines insect and disease control on labeled plants, useful when foliar issues overlap.
• Granules: Designed for lawns and perimeter areas. They’re spread with a broadcast or drop spreader and often watered in as directed.
• Compare labels: Check the pest list, approved use sites, reentry timing, and coverage. Product pages typically note square-foot coverage to help size your purchase.

Pick the format that matches your target area and the pests you’ve identified.
