Can You Use Old Insecticides And Pesticides?

You should not use old chemicals or any garden products that are two years old or more, because they may do more harm than good to your plants, or they could be ineffective.

If you wish to prolong the shelf life of your insecticides and pesticides, store them in a dry location free from extreme heat and cold. These chemicals do degrade over time, and you should label them with the date when you purchase them.

Where To Store Insecticides?

Store insecticides in a room with a temperature above 40 degrees Fahrenheit. Low temperatures will freeze liquids and will cause breakage to glass containers. Always refer to the package label for storage recommendations.

How Do You Know The Shelf Life Of Pesticides?

The pesticide's shelf life depends on its formulation, storage conditions, and container type. As a general rule, any unopened pesticide container stored at a moderate temperature could remain effective for two to five years.

Should You Use Chemical Insecticides On Your Plants?

There are things to consider if you choose to use chemical insecticides.

  • Check the label for the proper chemical you need for your plants. Ensure that the insecticide can work on the pest you are removing from your plants.
  • Ensure that the insecticides can only kill pests and will not harm your plants.
  • Follow the direction on the packaging. Learn how to use the insecticides, how much you should use, and how often to use them.
  • Do not use pesticides on hot, windy days. Using chemicals during hot weather has a risk of damaging plants.
  • Make a barrier around the plant you are targeting to protect other plants surrounding it.

How Do Insecticides Work?

Insecticides protect plants from damage caused by insects by killing them or preventing them from coming close to the plants. Most insecticides attack the insect's nervous system, while some act as endotoxins or growth regulators.
