Does Clove Oil Kill Roaches? The Truth Behind This Solution

Cockroaches reproduce quickly and can be challenging to eliminate once they inhabit your house. Consequently, it’s crucial to deal with roaches as soon as you notice them. You can try out different homemade DIY like clove oil.

Clove oil (Syzygium aromaticum) can kill and repel roaches because it contains Eugenol, a natural insecticide. Crushed cloves produce a strong smell that roaches don’t like, and they will keep away from it.

Using clove oil alone can be a good way of repelling cockroaches, but if you want to eliminate them, you might have to apply some degree of ingenuity.

Does Clove Oil Kill Roaches?

Clove oil can kill and repel roaches because it contains eugenol, a natural insecticide.

Crushed cloves produce a strong smell that roaches don’t like, and they will keep away from it.

However, clove oil alone may not be very effective in eliminating roaches, as they can run and wait until the oil dries out.

How long does it take for clove oil to kill roaches?

Clove oil takes about 6 hours to kill roaches and about 30 minutes to completely repel the creatures from an affected surface. However, the duration may vary depending on what you mix with the oil, its concentration, the extent of a cockroach infestation, etc.

Clove oil is often used as an additive to different types of insecticides. It is much more potent when mixed with chemicals such as diatomaceous earth (a powder-like substance formed by grinding fossilized diatom shells) and other treatments to attract and contain the insect’s populations.

How to get rid of roaches with clove oil?

You can opt for several techniques when dealing with a roach infestation within your space.  Although clove oil can kill cockroaches by itself, the insects are more likely to run and wait till the substance dries out. 

Clove oil without additives is better suited to repelling roaches rather than killing them. A downside to relying on a clove oil solution is that the remedy is only effective for a limited duration.

Mixing the oil with peppermint oil, citrus extracts, and other viable organic chemicals not only acts as a safe homemade solution to roaches but also helps to ensure that your mixture remains potent for longer.

Using clove oil without any additives

Clove oil has numerous uses and benefits within your living space. The oil doubles up as an organic solution to insect attacks, weed control, air purification, etc. You can also use clove oil for your hair and skin as a food additive.

You can try mixing clove oil with different bait types to ensure the insecticide becomes more appealing, lethal, and long-lasting. But clove oil works fine if you only intend to engage in DIY roach prevention. 

How you can make a clove oil insecticide at home;

Quantity: 1 liter 

You will need:

  • 1 Litre of warm water
  • 10-15 drops of clove oil
  • 10-15 drops of a liquid soap solution

  1. Mix 10-15 drops of clove oil concentrate with 10-15 drops of liquid soap stabilizer.
  1. Add about 1 liter of warm water to the blend and shake thoroughly.
  1. Pour the mixture into a spray bottle and spray under the sink, shelves, and other dark spaces where the insects are likely to hide.

Mix clove oil with Diatomaceous Earth

Diatomaceous earth (DE) is a fine powdery substance that effectively eliminates roaches and other pesky insects from your space. The product works by breaking down the waxy layer of the insect’s exoskeleton, causing it to die from dehydration.

Roaches carry the chemical to their hiding spots through their legs as they scurry around for food. Mixing clove oil with diatomaceous earth creates a potent and efficient method for controlling large cockroach infestations for a more extended time.

Quantity: 1 Liter

What you need:

  • 1-2 tsp diatomaceous earth powder
  • 10-15 drops of clove oil concentrate
  • 10-15 drops of liquid soap
  • 1 liter of warm water
  1. Prepare a clove oil-based insecticide by mixing10-15 drops of the oil concentrate with an equal amount of liquid soap stabilizer and shake thoroughly.
  1. Add a small amount of DE powder to the concentrate while adding water to keep the mixture from becoming too thick.
  1. Pour the blend into a spray bottle and spray on the affected areas.

Another alternative involves spraying the clove oil insecticide on its own before using a squeeze bottle to spread the powder over the moist surface.
