3 Plants That Repel Palmetto Bugs (Get Rid Of Them For Good)


Palmetto bugs are one of the most resistant cockroach species on the planet. They can withstand high levels of radiation and can go without food for up to 40 days.


In fact, in addition to poisoning palmetto bugs, chemicals also poison other animals, plants, soil and humans. Also, be aware that in general, these cockroaches are able to resist chemical insecticides. The ideal is thus to use plants that the palmetto bugs hate such as catnip, mint, or laurel.


How to get rid of palmetto bugs?

To limit the invasion, we advise you to replace dead or decaying wood with fresh wood or a new layer of mulch. Cockroaches are looking for water, humidity and heat and will seek another environment more conducive to their development.


Also look outside for possible sources of food: garbage, soft fruit, leftover lunch on the garden table, food and your pet’s water bowl. In addition, remember to close the lid of your garbage cans tightly to prevent the insect from coming to help itself at nightfall.


You can then place bait near the areas where you spotted the palmetto bugs: near your terrace or near vegetation. Although the baits and sprays that you will find on the market will kill individuals, be aware that these techniques are not very effective. It will take time without convincing results.


3 plants smells that palmetto bugs hate

The catnip

It is a scented plant which is generally used in decoration and medicine. However, it is also an insecticide that helps in the fight against palmetto bugs.


Like laurel, its scent keeps these pests away. Indeed, they cannot enter the house when they smell the leaves or catnip branches scattered in the house.


The laurel

A very fragrant shrub that has a scent that has the benefit of not pleasing the palmetto bugs, in addition to mosquitoes. In this way, it is quite possible to use it to fight against this particular pest.


Mint plant

Mint is supposed to be a good repellent because of its strong pungent odor that would bother the delicate sense of smell of palmetto bugs, in addition to rats and mice. They won’t care about peppermint in any form, plant, essential oil or lozenge.




Other ways to keep Palmetto bugs out of your house

Cucumber and bitter orange

Still in the list of cockroach repellents are cucumber and bitter orange. As with the first plant, these insects hate their smell. Here is how to use them :

  • Cut them into pieces
  • Place them in a container
  • To deposit them in the places where there are the most palmetto bugs.


Cayenne pepper

It is also used for the prevention of palmetto bugs. It can be used in two ways: sprinkled in the house or boiled with garlic and onion. For this second method, here are the instructions to follow:

  • Cut a clove of garlic and an onion into small pieces.
  • Add a quantity of cayenne pepper (enough to give off a strong smell)
  • Boil the mixture
  • Pour into several containers and place in places where these pests regularly pass through.


The onion

When combined with baking soda, onion is deadly to palmetto bugs. It is even one of the most widespread natural methods. The aim is to form a paste from the mixture of these two components. Here is how to proceed:

  • Chop half of an onion into thin slices
  • Mix it with two tablespoons of baking soda.
  • Put the dough in the path of the cockroaches

If this is not homogeneous, flour can be added.



It is a boron derivative that is generally used in the manufacture of detergents, but it can also be used to control palmetto bugs. Borax is a natural contact insecticide, meaning that insects dehydrate just by brushing against it. For it to work, it simply needs to be spread in the places most frequented by intruders. On the market, it comes in two forms:

  • White or colourless powder
  • Sequined

In any case, it is odourless. Its advantage: it is also used to exterminate wood-boring insects, i.e. those that gnaw on wood.


Are cockroaches afraid of insecticides?

These insects are very resistant, indeed, they present a notable defense against chemical insecticides. If you opt for more natural products or decoctions, you can try to combine white flour, sugar and plaster. The result should be placed near a flat container with water.


Another solution is to buy packets of boric acid in powder form. A spoonful of boric acid can be mixed with a spoonful of honey, a little water and a tablespoon of flour. Then, with this mixture, you will have to compose a ball. Make small piles in places where cockroaches circulate. You will get a guaranteed result!



It is always difficult to remain indifferent to a cockroach infestation. Not only do they carry disease, but they also give off a disgusting smell. Fortunately, there are natural solutions to eliminate them and keep them away from the house.


Laurel and catnip are two plants that have the effect of scaring away the palmetto bugs.
