The warmer months see insects emerge from hibernation and produce many generations of offspring throughout the summer. So, if you’re looking for a natural way to keep insects out of the house, then this is one of the best indoor plants for the job. 

How does eucalyptus keep insects out of the house? 

‘Pests are alarmed by strong smells, and eucalyptus is typically not a smell that is native to the area, so its unfamiliarity combined with its potency causes pests to perceive it as a threat,’ Jeremy says. However, you can use all the natural deterrents you want, but if you have holes or spaces for pests to enter your house, they will - so fix those spots first. If, for some reason, you can’t seal those entry points, make those points the focus of your eucalyptus placement for maximum deterrent efficiency. It is important to note, however, that this oil can be harmful to animals, so it is best to use it with caution if you have a pet. 

How to use eucalyptus to keep insects out of the house 

As Jeremy suggests, you can use eucalyptus oil to deter insects this summer, but you can also incorporate eucalyptus into your indoor (and outdoor) garden ideas with eucalyptus trees too. Here’s what you need to know.  

1. Use eucalyptus oil in a diffuser 

Lindsey Hyland, the gardening expert and the founder of Urban Organic Yield (opens in new tab), suggests filling a diffuser with eucalyptus oil to keep insects out of the house. This scent will ‘help to repel insects and keep them away from your home.’ 

2. Make a homemade spray 

You can also mix water and eucalyptus oil to create a homemade bug spray, which Lindsey suggests will deter insects from coming into your home. It is best to spray the mixture in problematic areas where the insects are likely to enter your home.  

3. Invest in eucalyptus trees 

Eucalyptus is at the peak of interior and garden trends this season, so it is only natural that you will want to enjoy the plant itself. And while the scent is not as powerful as the oil, these plants will still help keep insects at bay. Lindsey suggests that eucalyptus trees can help keep insects away as they will create a ‘barrier between your home and the insects.’ Now you have every reason you may need to enjoy the benefits of eucalyptus – the only thing left to do is make the investment
