David Grays Carbaryl Garden Insecticide 500ml – Caterpillar, Grasshopper & Chewing Pest Control

David Grays Carbaryl Garden Insecticide 500ml: Control for Chewing Pests

David Grays Carbaryl is a broad-spectrum garden insecticide that controls caterpillars, grasshoppers and other chewing insects on ornamental plants, lawns and outdoor areas. The active constituent is 100g/L carbaryl, an anticholinesterase compound that works on the insect's nervous system, and this 500ml bottle is a concentrate that you mix with water before spraying.

It's best understood as a chewing-pest product. Carbaryl is taken in as insects feed on treated foliage, which is why it's a go-to for the caterpillars and grasshoppers that chew leaves, along with lawn pests like armyworm. It covers a genuinely wide pest list, including leaf rollers, lace bugs, harlequin bugs, cabbage white butterfly caterpillars, cutworms, wingless grasshoppers, European earwigs, Portuguese millipedes, black-headed cockchafers and lawn armyworm.

Pests It Controls

• Caterpillars, including leaf rollers and cabbage white butterfly caterpillars

• Grasshoppers, including wingless grasshoppers

• Lawn armyworm, lawn grub and black-headed cockchafers

• Lace bugs, including azalea lace bug, and harlequin bugs

• Cutworms, potato moth and tomato caterpillar

• European earwigs and Portuguese millipedes

Where and How to Use It

This is a concentrate, so shake the bottle well, then mix with water at the rate on the label for the pest and situation you're treating. Spray thoroughly over the foliage so you cover both the upper and lower leaf surfaces, since good coverage is what makes a contact-and-ingestion insecticide work. It's suited to ornamental garden plants, lawns and general outdoor areas. Because the exact mixing rate depends on the target pest, follow the label rates rather than estimating.

Important Use Restrictions

Carbaryl carries some specific label restrictions that matter for both results and safety:

• Do not apply to food-producing plants such as fruit, vegetables or herbs

• Do not mix with lime sulphur or Bordeaux mixture

• Do not apply in hot or humid conditions, or if rain is expected within 24 hours

• Do not apply to plants that are dry or suffering from moisture stress

• Wear gloves and eye protection when mixing and spraying

Carbaryl is also harmful to bees, so avoid spraying flowering plants or spraying while bees are active. Keep it away from fish, ponds and waterways, store it in its original container out of reach of children, and always read and follow the full label.
