The best plants for natural pest control

Summer is the season when pests like flies, roaches, ants, and mozzies visit your home uninvited. You can use bug sprays and chemicals to alleviate the problem, but doing so may put people and your pet’s health at risk.

Toxic chemicals sprayed around your home leave poisonous residue for some time, unseen to the naked eye. As mentioned earlier, this can be a health hazard.

Adding plants inside and outside your home does not only repel insects and other pests naturally. It also eliminates the need to use toxic chemicals that may harm you and your family’s health.

What is natural pest control?

Natural pest control is the method of controlling pests and insects without the use of highly toxic chemicals, either creating natural elixirs and sprays or using flora which is the topic we will discuss in detail.

Some people prefer natural pest control to tackle problems with insects and harmful pests around their property for health reasons and to be eco-friendly.

Furthermore, to repel pests, you can use naturally-derived materials that keep pests away. These types of treatments include the technique of growing plants like rosemary, thyme, mint and many others.

Placing insect and pest repelling plants strategically around your garden or on the patio can help you enjoy spending time with family in your backyard comfortably. These plants can help create a pest-free garden year-round.

Remember that the first line of defence to protect your family against harmful pests is to prevent them from getting inside. Take advantage of the beneficial properties of deterring plants you can grow as hedges around your property.

Of course, plants that deter pests are often called low impact, but that does not mean they aren’t effective. Nature’s gifts have guaranteed performance without leaving you with the many disadvantages that synthetic chemicals do.

This plant contains citronella, a chemical that we all know has a pest-repelling ability. You might love the aroma that lemongrass emits, but insects detest it.

Outdoor plants that deter pests

Natural pest control for plants and veggies requires a little bit of effort, but it’s worth it. You can imagine putting in the effort to grow food in a raised bed around your home. Then, having it ruined by pests is very disheartening. Although there are insecticides you can buy, chemical treatments generate harmful effects on your vegetables and plants too.

An all-natural DIY pest control spray is a great alternative. However, if you are not familiar with mixing the right ingredients, you might not be able to create an effective repellent solution.

Furthermore, frequently spraying your vegetables with natural insecticides to keep pests away is a time-consuming task. What you need are pest control plants for the garden that work wonders at naturally preventing pests.

Weeds are a headache not only to professional gardeners but even to newbies who love to grow food and flowering plants around their backyard.

In making your garden free of weeds, some plants can help you get rid of weeds without resorting to synthetic chemicals.

Low growing shrubs

Tucking plants like hosta and corn bells around small trees can help control weeds. Creeping shrubs that grow very low is another option you can use to control weeds. They are fast-growing and can cover a specific area you want to suppress weed growth quickly.

Impatiens and petunias

Impatiens and petunias are flowering plants often used as weed suppressants. You can grow them as ground cover and make your garden bed colourful while eliminating the chance for weeds to invade spaces you don’t want them to be. These plants are excellent in repelling aphids too.

In addition to vetiver grass and catnip, marigolds, mint and garlic were recommended by EPA for the control of termites.

These houseplants are versatile as marigold can add a kerb appeal into your home with its bright colour, while garlic is excellent in spicing up your cooking.

Grow these annuals, and enjoy their naturally beneficial components. These include getting rid of termites around your home.

Making your home pest-free through a DIY pest-control plant project is not as difficult as you think. Mother nature provides you with the best plants to naturally repel pests around your home.

Of course, you can get pest control chemicals from Bunnings, or hire a pest control service. However, some people prefer not to use chemicals around the house as they could be harmful to the health of the people and animal residents who live there.

Taking advantage of nature’s gifts can save not only time and money, but it also eliminates the possibility of causing a threat to your health over the use of toxic chemicals.
