If you’re like me, you’ve probably wondered, “does lemon juice kill roaches?” The short answer is yes, it does! Lemons, with their antipathogenic properties, are a natural and effective way to keep roaches and many other bugs at bay. Roaches can’t stand the strong citrusy smell of lemons, which makes them a great deterrent.

How Can You Use Lemon To Kill and Repel Roaches?

Now that we are aware that lemons can serve as a roach deterrent, let’s delve into the practical aspect of employing this natural solution.

Squeezing Out Lemon Juice

A great way to make use of this citrusy weapon is by extracting lemon juice and putting it directly on roach territory. Here’s what you can do: take some lemons from your refrigerator and squeeze out their juice. Take that extracted juice, transfer it to a spray bottle, and sprinkle it on known roach infestations. To get the most bang for your buck, target the lemon juice directly onto the roaches themselves. If you’ve noticed roaches in your cupboards, closets, or the cracks of your windows, don’t hold back; squeeze that lemon juice right on them!

Drying Lemon Peels

Do not, I repeat, do not discard your lemon peels after extracting the juice. These peelings are just as valuable as the juice itself. You see, the harsh, citrusy taste and smell of lemon peels are hated by roaches. So consider drying these peels, grinding them into a fine powder, and then using this to further your roach repelling mission. Sprinkle this powder in areas where you’ve noticed roaches or even at your home’s entry points to discourage these pesky bugs from stepping foot into your space.

Preparing Lemon Water

Lemon water is another fantastic, easy-to-prepare solution. All you have to do is cut lemons into two pieces, add them to boiling water, and let it simmer until it reduces to a quarter of the original volume. Use this lemon-infused water at places of infestation. Like lemon juice, this potent concoction can be used to wipe down areas where you’ve seen cockroaches, effectively repelling them. Moreover, if you spot eggs or smaller roaches, this lemon water can help remove them instantly.

Using Whole or Sliced Lemons

Aside from these approaches, whole lemons or their slices can also be handy. The strong smell of lemon serves as a red flag for roaches, making them scuttle the other way. Using slices or whole lemons in high roach traffic areas will help maintain a vermin-free zone.


So does lemon juice kill roaches? It’s not a silver bullet but it can be a useful tool in your pest control arsenal. The strong citrus scent of lemons can deter roaches and keep them at bay. While it may not eliminate roaches entirely, it’s a natural, non-toxic method that helps in controlling them. It’s important to remember though, that using lemon is just part of a comprehensive approach to roach control. Alongside this, maintaining cleanliness and sealing off entry points are crucial steps in keeping these pesky bugs out of your home.
