Importance of Using Beneficial Insects for Gardens

The most crucial benefit of using beneficial insects is the reduced use of chemical pesticides. This approach eliminates the entry of toxic chemicals in organic gardens. With this, there are no worries about consuming any chemicals along with food. The use of chemical pesticides is not efficient for killing all kinds of bad bugs and pests. Applying chemicals to your garden will also kill beneficial insects that would be helping your garden stay healthy.

If you keep adding chemicals to deal with insects, the insects can become resilient to chemicals. Chemicals will become useless. According to a statement of pesticide action network, more than 1000 weed species and insects have developed resistance against the registered pesticides. So even the effectiveness of pesticides is not guaranteed in this situation. By using beneficial bugs, the cost of expensive chemicals can be greatly reduced. You attract beneficial insects to your garden easily, reducing the need to spend money on chemicals.

Regulations Before Introducing Beneficial Insects 

All insects have different mechanisms of interaction in different environments and seasons. So, before introducing beneficial insects, it is necessary to consider some crucial points. It is must to follow the permits and regulations. It will be courteous to inform your neighbors if you are going to add beneficial insects to the garden. In addition to the introduction of beneficial species, it is essential to ask neighbors to minimize the use of chemical sprays; otherwise, it will indirectly affect your garden as well. It may happen that the neighbors also become willing to share the cost of purchasing and introducing beneficial insects. 

Just like other living organisms, beneficial insects also need an optimum environment, such as vegetation and climate. It is entirely dependent on the gardeners to provide a suitable habitat for the beneficial insects. It is also essential that the population of pests in the garden should not be more than what the insects can handle. If you have a massive infestation of pests, then chemicals may be necessary. If there is no population of pests in the gardens, then the introduction of beneficial insects is not useful as they may leave your garden in search of a more reliable source of food.
