Eliminate Insects, Bedbugs, and Flies Naturally: A Simple DIY Solution for Your Window Rails
As the warmer months arrive, so do the bugs—from buzzing flies to sneaky bedbugs that seem to appear out of nowhere. But before reaching for harsh chemical sprays, consider this: there’s a safer, natural alternative to keep insects at bay, using common ingredients you probably already have in your kitchen.
This DIY insect-repellent spray is simple to make, highly effective, and gentle on your home and the environment. Here’s how you can protect your window tracks—and your peace of mind—naturally.
How Insects Find Their Way Inside
Flies, bedbugs, and other pests are attracted to warmth, moisture, leftover food, and even dust. They often enter through small cracks, open windows, or door gaps. Even in the cleanest homes, bugs can still sneak in. That’s where natural repellents come in—offering added protection without the harmful side effects of chemicals.
A Natural Bug Spray That Actually Works
This all-natural solution targets one of the most overlooked entry points: your window rails. That’s where insects often crawl in or gather. The spray uses just four simple ingredients:
-
Rubbing alcohol – disinfects and naturally deters insects
-
Ground cinnamon – repels bugs with its strong scent and antimicrobial qualities
-
Used coffee grounds – discourage nesting and create a scent barrier
-
Distilled water – helps everything mix well and apply evenly
How to Make the DIY Insect Spray
Ingredients:
-
1/2 cup rubbing alcohol (70% or higher)
