Where Stink Bugs Come From: The Unwanted House Guests

Stink bugs are pesty insects that can be a nuisance to homeowners. These bugs tend to seek shelter in the comfort of our warm homes during the winter months. As soon as spring arrives, they invade our gardens and crops, causing great damage. In this article, we will dive into where stink bugs come from and what we can do to prevent them from being our unwanted house guests.

The Origin of Stink Bugs:

Stink bugs, scientifically known as Halyomorpha halys, originate from Asia. These bugs were first spotted in the United States in Pennsylvania during the late 1990s. After that, they gradually spread across the country and can now be found in 44 states. Stink bugs are sometimes referred to as shield bugs due to their characteristic shape.

Stink Bug Appearance:

Stink bugs can be identified by their unique physical features. They are about .5 inch to .75 inch long and .3 inch to .4 inch wide. Stink bugs have a brownish-grey color and usually have the shape of a shield, which is why they are nicknamed the shield bug. When threatened, stink bugs release a foul-smelling liquid from their glands, which is why they are called stink bugs.

Life Cycle of Stink Bugs:

Stink bugs have an interesting life cycle that lasts one year. These bugs lay their eggs during the spring season. The eggs hatch into nymphs, which are black and orange in color. The nymphs gradually grow into adults, and the process can take up to six months. During the winter months, adult stink bugs seek shelter in the warmth of our homes. However, in spring, they venture out to feed on plants as they wait for the next breeding season.

Why Stink Bugs Invade Our Homes:

Stink bugs mostly invade our homes during the winter months to seek shelter from the cold. These pests tend to crawl into any crevice or gap they can find, such as windows, doors, siding, and foundation cracks. They eventually find their way indoors in search of warmth and shelter. While stink bugs do not cause any harm to humans, they can be a significant nuisance.

Remedies to Keep Stink Bugs at Bay:

Many homeowners struggle with stink bugs, and it can be challenging to keep them at bay. Here are some remedies that can help prevent a stink bug invasion:

1. Block Their Entry:

The first and easiest way to prevent a stink bug invasion is to block off their entry points. This can be achieved by sealing any cracks, gaps or entry points in your home. Be sure to inspect your home for any possible points of entry, such as doors, windows, and siding.

2. Use Essential Oils:

Stink bugs are repelled by the scent of certain strong essential oils, such as lavender, peppermint, tea tree, and eucalyptus oils. You can use these essential oils to create a natural remedy to repel these pests.

3. Sticky Traps:

Sticky traps can be an effective way of trapping stink bugs. These traps contain an adhesive agent that sticks to the bug, preventing it from escaping. You can place these traps near entry points and along walls to catch these pests. However, if you catch them, remember to dispose of them carefully and quickly as stink bugs tend to produce a foul odor when they die.

4. Insecticides:

If the stink bug invasion is significant, you can use insecticides to keep them at bay. Insecticides are readily available in stores and can be used to create a barrier around your home’s exterior to prevent stink bugs from entering your home. However, make sure to use the insecticides carefully as they can also harm beneficial insects that are necessary for your garden.

The Bottom Line:

Stink bugs can be a significant nuisance to homeowners, but with proper prevention methods, you can keep them out of your home. Be sure to seal any gaps and entry points, use essential oils, sticky traps or insecticides as a remedy, and you can be stink bug-free.
