When you set out to control harmful pests, it’s important to realize that poor judgment may destroy useful creatures as well as harmful ones.

Should I spray my vegetable garden?
Many gardeners rely on chemical insecticides to eliminate the harmful insects competing for their crops. Some, however, object to the use of chemicals. These gardeners prefer to rely on organic, or non-chemical, means of control. The surest way to control most insects and similar creatures that threaten your vegetable crop is by using a chemical insecticide.
What pesticides are safe for vegetable gardens?
If you decide to use a pesticide to control insects in your garden, here are some important points to remember:
- Read the label completely and follow the instructions
- Wear protective equipment such as gloves, goggles, long sleeves, and pants while handling the product
- Do not breathe in the spray or dust
- Use the product when the weather is calm and not windy out
- Wash your clothes after using chemicals and any equipment you may have used to apply spray as well
A pesticide is any form of chemical control used in the garden. An insecticide is a pesticide used specifically to control insects. A herbicide is a pesticide used to control weeds. If you mistakenly use a herbicide to control insects, you’ll lose your entire crop for the season because it will kill your vegetable plants.
What can I spray on my vegetable garden to kill bugs?
The spray type is bought in concentrated form, diluted with water, and diffused with a hand sprayer or a spray attachment fitted to the end of your garden hose. Dust-on insecticides are powders that you pump onto the plants. Spraying is preferable because it gives more thorough coverage. It’s also easier to treat the undersides as well as the tops of leaves and plants with a spray.
