Houseplants that Keep Bugs Away

Let’s face it, bugs exist and they are living organisms that also need food and shelter. Both of these may be available in our homes which is why they may visit us often or even become our housemates. Unfortunately, these uninvited guests secretly eat a share of our food, are annoying, scary, and even bite. The bites of these bugs may cause redness, swelling, itchiness, and irritation to the skin.

In worst cases, their bites may trigger severe allergic reactions like anaphylaxis, which may be lethal, especially if not applied with a proper first aid treatment. Furthermore, these bugs may also transmit diseases that may be deadly through their bodies and their bites. Such undesired effects may be avoided if these bugs cannot enter our homes in the first place. Fortunately, this may be possible with the help of the below house plants that are said to be effective in repelling bugs.
