Natural Repellents

Pests, insects, and bugs are part of nature—insect pests come in many forms and can do varying degrees of damage. For example, house flies are not only annoying, but they may also carry disease-causing germs. Termites can destroy property. Mosquitoes and bed bugs cause discomfort by sucking people's blood and spoiling their sleep. Thunder flies and corn borers destroy crops.

Many commercial repellants are available in the market. Unfortunately, they are loaded with chemicals that can harm human beings. It is advisable to find alternative ways to repel harmful insects, bugs, and pests.

To the best of my knowledge, termites hate catnip and vetiver grass.

Gary Danjou on March 10, 2018:

What plant fragrance is good to stop termites??

Cinfy on October 29, 2017:

I raise Monarchs in the summer and want to keep predators off the milkweed.

What can you recommend that won't also repel the adult female from laying eggs on the milkweed?

Welcome.

Very helpful information. Thank you.

Tomato leaf spray and garlic oil spray are effective against aphids.

Colin Peckham on April 25, 2017:

I have two problems in my very narrow shaded garden beds.

1. I get lots of aphids on my climbers, and ants travel up to get and harvest them. I would like to plant something underneath the climbers that would deter them, but its very shady at ground level, and the aphids are often at high level. Most plant deterrents appear to be sun loving herbs, so is there anything else I could use.

2. Ants: I am using diatamaceous earth which they dont like as well as taping the base of things and putting vaseline on it, and this seems the best way to stop them climbing up plants and structures.

Srikanth R (author) on February 23, 2017:

Yes. Also try camphor plant, sweet pea, lavender, daffodils and catnip.

Mary Norton from Ontario, Canada on February 22, 2017:

I was happy to have seen this hub. I plant mint and basil and love them in food but did not realize they are good for repelling insects. Do you have to put a lot of mint to repel mice?

Srikanth R (author) on February 06, 2017:

Hi Joyce! If none of the remedies I have mentioned work, it is advisable to contact an expert locally.

Joyce on January 30, 2017:

I fail in my attempt at organic gardening for the past two years. This is due to the fact, I have a infestation of Japanese beetles and aphids and spider mites. I have used milky spore for 2 years straight with only a small different with population of beetles. The aphids and spider mites have been resistance to even chemical pesticides. How can I get rid or keep these pest at bay?

Srikanth R (author) on August 25, 2016:

If you can manage to grow them indoors, if you have space, light, etc, nothing like it. You just need to ensure their good health.

CLD on June 10, 2016:

I have raised beds for my garden, do I have to grow these things inside or can I place additional pots around the boxes or sprinkle the herbs on the garden? What is best?

Srikanth R (author) on May 12, 2016:

Well, the fact is carpet beetles hate sweet woodruff. They run away from this flowering perennial plant.

Donna on May 12, 2016:

I've just seen a site showing carpet beetles feeding off the sweet woodruff plant, with statements by other people saying they've found this also. Your site says sweet woodruff repels them though! I'm not sure what's correct now - please help. Thanks.

Srikanth R (author) on July 19, 2015:

Basil is effective against most of these.

Howard on July 17, 2015:

In your introductory paragraph Srirad you mention Thunderflies (in the UK) but not which plant is the best deterrent. Can you offer more advice please? I have a problem with them crawling into my large computer monitor behind the clear and then dying inside to remain there forever...! Very annoying...! So I will need to place around the monitor whatever plant you suggest, is that practical?

Srikanth R (author) on June 12, 2014:

I am glad that the hub was useful.

Lizolivia from Central USA on June 12, 2014:

Very useful information. I grow many of these plants in the garden such as coriander, marigold, thyme, basil, rosemary, nasturtium, chives and mint. I didn't know about bay leaves repelling weevils in dry grains and the red pepper with dish liquid mixture to repel ants. Thanks for the helpful tips.
