7 Homemade Bug Sprays For Indoor Plants

Having a go to DIY homemade bug spray for indoor garden plants is a must in my house. Years ago people only thought about plants belonging in the vegetable garden and out in the sun. 

They were used to placing them away from homes and indoor spaces.  But today, that’s just not the case anymore.

7 Homemade Bug Sprays For Indoor Plants

We love having plants in our homes and offices.  It’s one of the simplest ways to bring nature inside.  Whether you live in an apartment or you work in a high rise, you can grow your own little garden indoors in boxes, pots, or hanging planters.  They help us relax and bring some of the outdoors inside.

Houseplants are the best natural air purifiers.  They cleanse the air from toxic chemicals and raise the air’s humidity to protect us from dry coughs, sore throat, and respiratory problems.

If you’re feeling stressed at work, having plants in your office or home can lower your blood pressure, heart rate, and respiration.  They help reduce your stress and anxiety.

However, one of the pest problems you can face when keeping plants indoors is different bugs and adult fungus gnats especially.  These little insects and natural predators live and feed on the leaves of your plants.  They are not only annoying — they can do serious damage to your plants, too.

Make sure to do a closer inspection of your plant every now and then to check for signs of pests. If there is a sticky substance or black spots on your plant, that could be a sign you’ve got a pest you need to deal with.

However there are different ways you can get rid of these aphids, mites, and other creepy, crawly creatures, including beneficial insects with a bug killer for indoor plants.  You don’t have to use chemical pesticides, insecticidal soap, or even vegetable oil which large numbers of people used years ago to treat for bugs indoors but that made quite a mess. 

They are not only dangerous for you, your family, and your pets, chemical pesticides are also very expensive and do not always work.

But, we also want to be sure we use all natural pest control on the house plants and all natural garden pest control.  So if you’re looking for the best homemade insecticides, best indoor use bug spray, best organic common houseplant pest control, best bug killer for indoor plants, or just great natural pesticides and bug spray for your healthy plants, we have you covered. With these homemade sprays made, with more natural ingredients!

Instead of using store bought pesticides for chemical control with who knows what in them, (I mean, I know they print what’s in it on the product – but I am not a scientist, so I have NO idea what they are!) you can try these homemade bug spray recipes for your indoor plants. 

They are safer and more effective methods of getting rid of the indoor plant pests and indoor plant bugs your houseplants may encounter.  Most of the items to make these you might find you already have at home!
