These are tried and tested methods that are usually used by farmers and gardeners trying to go for 100 percent organic gardening. So If you are not interested in any chemical insect killer and want to control your garden pest in an organic way then bellow mention tips are for you.

 Beneficial insects

As mentioned, where some insects damage your crops, some are considered beneficial for your gardens. Ladybugs and damsel bugs eat the pests and creatures that are harmful to your garden.

 Diatomaceous Earth

Diatomaceous Earth
Diatomaceous earth is soil-like material that can be spread on the ground of your garden. It is extremely harmful to the pests but is not at all toxic for other animals, humans and the environment. The Diatomaceous Earth basically works by damaging the exoskeleton of the insects leading to death eventually.

 Intercropping

Intercropping means planting different types of crops or plants next to each other. This is different than the traditional methods, where all the same type of crops are planted together. The heterogeneity confuses the pests and it gets difficult for them to find the type of plant they want to munch on.

Handpicking

This might sound gross, but it is one of the most effective methods to prevent pests from infesting your vegetable garden. If you don’t want to use a chemical insect killer, there is a huge chance that pests will show up in your garden every now and then. Hand-picking them every few days will keep their population in control. However, make sure you wear gloves before you touch the creepy crawlers.

Garden insects and pest identification

There are hundreds of different types of garden insects. The type that prevails in our garden depends on the type of crops we have planted and the area we live in. It’s not possible to talk about all of them. In this article, we’ll talk about some of the most common harmful garden insects and pests that are usually found in North America.

They are as follows…

 Slugs

slugs

The most common type of garden pest is a slug. If you live in a moist and humid area, you might find many of these lingerings around your garden. They are not exactly insects rather are soft-bodied mollusks. These little creatures are by far the most damaging and can consume your plants at an alarming rate.

 Squash bugs

Squash bugs

These are small ant-like bugs that mainly attach squash and pumpkin plants. As a matter of fact, all plants belonging to the cucurbit family are endangered by these insects. These bugs or insects sap out the leaves leaving yellow spots that later turn into brown. If you see any such spots, that’s your cue. These bugs also called leaf-foot bugs, leave a cluster of eggs on the plant leaves which can also be taken as an indication.

Aphids

Aphids

These insects usually attack growing plants due to which flowers and fruits can grow up to be deformed. They are sap-sucking insects like squash bugs. Viruses and diseases usually spread due to feeding aphids. They cause galls to form on roots and leaves which are an indication that your plants are being preyed on. Fortunately, they are very easy to spot and kill.

 Japanese beetles

Japanese beetles

Japanese beetles are one of the most common pests that are found in moderate temperature areas. They feed on more than 300 species of plants. They chew anything and everything from grassroots to fruit plants. This can kill a whole plant by ingesting the roots. The best way to kill them is either by using neem oil or by chemical insecticides.

Types of insecticide

Powders-specks of dust

As the name suggests, these insecticides are in powder or dust form. Some need pre-use preparation such as mixing in water while others can be dusted on the ground and on the plants. This type of insect killer is not suitable for the regular rainfall area. Because then these types of insecticide can easily be wasted away and contaminate our environment and water. So its always better to use powder insecticide during the dry season or in an area where rainfall is not regular.

 Granules

These insecticides are similar to the powdered ones but are more manageable. Granules are mostly added directly to the soil.
