Most people who have a garden are alarmed by the sight of any kinds of insects. The first reaction to bugs is always disgust and most people decide to use pesticide in order to protect their flowers and plants against invasions of a variety of insects.
This is a natural reaction in a way because there are many insects that feed on leaves of the plants and if there are too many of them, they can cause serious damage to the garden.
However, you should be aware that there are actually many kinds of insects that are very important for the good health of your flowers and plants. Keep this in mind and don't get alarmed when you see them in your garden. These are the good guys!
Some of the most common are the following:
Dragonflies
Dragonflies are beautiful and colourful, and they fit with the lovely flowers in the garden. They have silk like transparent wings and various sparkling colors. They will eat mosquitoes and many other annoying pests that endanger the plants. Dragonflies like water and moist, so they will be attracted to a garden which has wet soil or maybe a fountain or pond in it.
Ladybugs
Ladybugs are very pretty bugs with their little red coat and black dots. But they are more than just pretty: they are very beneficial for your garden because they eat aphids! Aphids are very tiny insects, also know as plant lice, since they eat the leaves of plants. They live in colonies and they can reproduce very fast. Ladybugs also lay their eggs in these aphid colonies, to insure the Ladybug young will have enough to eat when they hatch.
Parasitic Wasps
Of course not all beneficial insects are as pretty as ladybugs or dragonflies. Wasps are thought to be evil and dangerous, but actually there are some wasps that are beneficial for the garden and harmless for humans: the parasitic wasps. They feast on small worms and other harmful creatures that live on your flowers. Parasitic wasps like humidity, so they will be attracted by moisture the same as the dragonfly.
The praying mantis
The praying mantis is a very interesting insect, many people are fascinated by its looks and size. This insect is so beneficial that it can actually be purchased as an egg and placed on a leaf until it hatches. Since they have a big size, they can eat big insects that are harmful for the plants, such as crickets, large beetles, flies, moths, and so on.
Green Lacewings
The green lacewing is another beneficial insect. It is great for natural aphid control. These pretty insects are very tiny, they have transparent, greenish wings. Since they are very small, they can't eat other insects, but they can eat their eggs, and thus keep insects like caterpillars and flies away from flowers. They also consume a large number of aphids every day.
Don't Use Pesticides!
Next time when you want to use pesticides in your garden, think twice. Most of the chemicals kill not only the harmful insects, but also those which are beneficial insects for your garden.
There are many ways to attract these little helpful gardeners.
Some of them can be purchased, while others are attracted by certain plants or conditions. Remember, a garden looks much more alive and natural with some insects living in it.
Beneficial garden insects will help reduce or eliminate the need for toxic pesticides by providing natural pest control for your garden.
How do you go about attracting beneficial insects to your garden?
Apparently, buying and releasing beneficial insects are the best approach that will achieve good results. For example, if you want to get rid of aphids then it is better to release aphid predators such as aphids midge and aphids parasites.
