15 Indoor plants that repel insects
Growing indoor plants that repel insects is a natural way of keeping them away from you or your home. Using this natural way to keep insects away is the best option.
However, some indoor plants can be toxic for pets. If you keep your indoor plants out of the reach of your pets, they will do their duty very well and keep the insects away. And they will also smell good.
Below, I have mentioned some indoor plants which are excellent choices for keeping bugs and insects away.
So, without any delay let’s look at 15 indoor plants to keep pests away:
It is believed that burning sage helps to get the negative energy out of homes. For using them as a repellent, take cuttings regularly, dry them up and then burn them. They will keep ants, flies, and mosquitoes away from your homes.
If you want to grow sage, make sure you give them direct sun. A south or west-facing window would be great. Soil should be well-drained. Maintain temperature between 60°F-70°F. Water them regularly.
As these plants will remain under the direct sun, they will need more water. But water them only when the soil is dry. They won’t like standing in wet soil.
Basil is a popular herb. They are used in preparing food and work great as a repellent, especially for flies. They produce an intense smell that flies cannot stand. They are even safe for pets and children.
Basil grows best when exposed to the direct sun daily for 6 to 8 hours in the day. A south or west-facing window will work great. This herb enjoys moist soil conditions, so they need to be watered frequently.
