However, you may want to proceed with some caution. Instead of blasting these mischievous beasts with chemicals, you can instead introduce a popular fall flower to naturally repel them. The flower in question? A chrysanthemum. This stunning plant will help you to naturally deter any cockroaches that dare to enter your flourishing garden space, leaving you to tend to your plants in peace. As a result, you should end up with a thriving garden — as long as there are no other lurking invaders marching across your land.

Thankfully, you can get this natural solution up and running quickly. So, how exactly do you use these flowers to your advantage? Below, we’ll break down the most straightforward way to utilize them. Now, you can get ready to lock down your plant-filled fortress once and for all.

It’s no secret that chrysanthemum flowers can help to ward off pesky cockroaches, but how do you use them? All you need is to take some that are already or almost flowering and plant them in your garden. This should be done during the months of spring, and they are one of the many perennials that will bloom every autumn. Alternatively, you can also temporarily use some chrysanthemum cuttings. Either option should work, but planting the flowers and allowing them to root helps you reap long-term benefits, and it will require less effort on your end in the future. 

Of course, you can always plant more if you feel it’s necessary. This tactic will likely have a greater impact compared to only planting one or two. However, you’ll be able to see what works and what doesn’t as you begin to observe your results. You can adjust your planting accordingly once you know what’s going on. Don’t worry — you won’t need to spend a fortune.

So, what is it about chrysanthemum flowers that cockroaches hate so much? As it turns out, cockroaches are very sensitive to odors. This explains why they are easily repelled by your flowers, which have a unique scent. Although it smells pleasant enough to us humans, cockroaches are simply repulsed by it. Of course, this makes mums the perfect option for warding off these pesky beasts. However, using this method doesn’t come without its downsides.

One pitfall of this hack is that it may not be effective during certain seasons, as the flowers don’t bloom all year round. This will affect the strength of their smell and how well it can repel cockroaches. Once the odor is gone, you may find that the army of dreaded cockroaches is once again knocking on your garden’s door. Instead, you may have to resort to using other methods.
