Top 9 Ways To Keep Stink Bugs Away - The Pest Rangers

What Are Stink Bugs?

The brown marmorated stink bug is a small insect typically found in gardens, fields, or around homes. An invasive species native to Asia, it was mistakenly brought here in the mid-1990s.

The defining feature of these insects is the scent they release when deterring predators. While they may seem non-threatening, they can cause some pretty big problems for such little bugs.

How to Identify Stink Bugs

Stink bugs are known for their distinct appearance, most notably their shield-shaped torsos and speckled brown coloring. Stink bugs also have smooth, rounded shoulders and alternating dark and light bands on their abdomen and antennae.

On average, stink bugs are about 12-14mm long and known to be pretty good flyers. While the sound of them buzzing around your head may be worrisome, they will not sting you.

Before they hit maturity, their earlier form is known as a nymph. Unlike the brown color of the adult, the immature nymphs are yellow and red with red eyes. As they mature, the yellow tapers off to white.

How do stink bugs get into my home?

Like most insects, stink bugs enter a home through the smallest of openings—ripped or torn window screens, gaps in a window or door frame, or cracks in a wall.

Once inside, stink bugs are skilled at hiding and prefer low-traffic areas of a house. Look for them in folds of curtains or draperies, attics or crawl spaces, or basements.

The most effective way to protect your home against stink bugs is to secure any openings. Walk around your home’s exterior and inspect it closely. Seal any cracks or crevices, close all windows and doors tightly, and fix any gaps in windows or door frames.

What Attracts Stink Bugs to Your House?

There are a few main reasons stink bugs enter residential homes, with the biggest being warmth, food, and light. Stink bugs cannot survive the harsh temperatures during the winter months, making them more likely to seek the warmth of your home this time of year.

Stink bugs are also in search of food, particularly fruits and vegetables. Keeping your kitchen clean and properly disposing of garbage can deter these pests from entering your home in search of food. Lastly, stink bugs are drawn to light sources, which is why you may notice these pests swarming around lamps and outdoor lighting.

9 Ways to Get Rid of Stink Bugs

1. Essential Oils

An easy and natural way to repel stink bugs and other winter pests is by using essential oils like mint. Mint is a pleasant herb that emits an aroma that stink bugs can’t stand. It acts as a repellent, not a killer.

Lemongrass oil is another essential oil you can use to deter stink bugs from your home. These are safe and non-poisonous deterrents that can leave your home smelling fresh as well. You can spray a mixture around window frames, doors, or any possible entry points.

2. Diatomaceous Earth

Diatomaceous earth is a natural sedimentary rock that will keep stink bugs away. This compound contains silica, alumina, and iron oxide. This rock breaks down the protective waxy layer on the exoskeleton and dehydrates it, making diatomaceous earth effective in getting rid of stink bugs.

If you choose to use this method, be sure it isn’t heat-treated. You can spread this around any point of entry, and it will kill off invaders.

3. Garlic Spray

Another potent but non-deadly repellent is garlic. While humans may love this delightful and flavorful bulb, stink bugs are less enthusiastic about it. This natural method keeps stink bugs away with an odor they can’t stand. Spread garlic cloves on window panes or create a spray to deter any would-be pests from entering or staying in your home.

4. Block All Entryways

The best way to keep stink bugs away is to stop them from entering in the first place. Preventing stink bugs requires a thorough inspection of your property, so be sure to check your windows and doors for any cracks or open spaces.

Additionally, make sure all screens are patched or replaced. Cover vents and any other openings with a screen as well. Another step you can take to be sure these pests stay away is putting up repellent. You can use dryer sheets on screens, spray garlic or mint, or spread the diatomaceous earth. Build up a barrier to keep stink bugs out!

5. Vacuum Them Up

If stink bugs manage to sneak their way inside, an easy way to take care of them is by vacuuming them up. You don’t want to squish them; otherwise, you will get to experience why stink bugs are called stink bugs.

You can trap these invaders in a sealed bag or container by scooping them up in a vacuum. After vacuuming, empty them into a trash bag and seal it tightly. From there, you can discard the bag outside or put the bugs in soapy water, ultimately killing them.
