How Pest Repellent Plants Save the World

Plants are useful, no question about it. Other living beings depend on them for food. Humans and animals won’t be able to survive without the oxygen that they release. Most plants around us can be used to cure a lot of diseases. However, one uncommon use of plants is their natural ability for controlling pests.

Can you imagine a world with no pest controls? What would happen to our food when they are not safe from meddling insects? How can we sleep soundly if we can’t get rid of the bugs under our beds? Will we be confident with our clothes if they are torn and threadbare because of rats? Would it be safe to live in houses which foundations have been eaten up by termites? Will there be crops to harvest if pests have already taken over them? How can we protect ourselves from getting sick if there are disease-carrying creates strolling around us? Surely, it would be chaotic without pest control.

But the world has survived against pests even before men discovered chemical pesticides and insecticides. How? The world is saved by plants which are naturally pest repellents. These plants are called pest repellent plants. They keep our food safe from the dirty feet of bugs. They make our beds comfy from sleep-depriving creepers. They safeguard our belongings from biological crop-raiders and shelter-burglars. They cloak us from deadly infections.

There are intelligent people who have created hand-operated or electricity-activated instruments to chase off pests like fly swatters and rat traps. But unlike these implements, pest deterrent plants don’t come with a price and are readily available. They have been on earth for millions of years waiting for us to utilize them to their full potential. And even if chemists have formulated artificial versions of these pest management plants, the synthetic ones are considered detrimental both for humans and for the whole ecosystem.

How do pest control plants work? They contain biological substances, those which are not meant to harm other living things, but can drive away pests, insects and other animals. A number of them have really strong odors which pests loath so much they will try their best to move away from them. These plants are fit for wrapping other plants, especially crops from infestations. By placing crops with adjacent to pest repellent plants, destructive insects will think twice before attacking.

Some pest repelling plants are also useful for maintaining a house free from usual household pests. Some may be strategically positioned near doorways and windows to avert pests from getting in. They are located inside or outside the house while taking into consideration their sunshine needs.

However, some of the plants that battle against hostile and virus-carrying pests have certain limitations. They need human intervention before their abilities are activated. For example, their leaves must be crushed to give off the pest-repelling substances that they hold. Extracts from the leaves and other plant parts are rubbed on clothing and other effects for pest protection.

Even with these manageable limitations, pest repellent plants have really saved, and still are saving, the world.
