When the majestic Wasatch Front begins to show its autumn colors, Salt Lake City homeowners look forward to the crisp weather. But unfortunately, this season also brings the large-scale invasion of the Box Elder Bug. These are red-striped insects and are generally harmless to humans. But they can be a nuisance in the house if present in large numbers.
If you live in a neighborhood with mature trees, especially in areas like Sugar House, The Avenues, or along the East Bench, and your home is south-facing, you are the number one target. The entire population is actively migrating from trees to your structure.
Do not let thousands of Box Elder Bugs crawl on your walls and invade your living space. Protect your home’s boundary today and call experts from saelapest.com for an autumn inspection.
How Salt Lake City Sun Trap Is A Seasonal Strategy
Box Elder Bugs are a big nuisance pest. Their behavior in Salt Lake City is entirely dependent on the sun and the colder season. They spend the summer feeding on Box Elder trees (their preferred host). You will also find them on maple, ash, and other deciduous trees common in older Salt Lake neighborhoods.
When the days become short and the nights become colder, the bugs start to mass-migrate towards homes that offer warmth and security.
A south-facing home experiences the most of the sun and holds the maximum amount of daytime heat. It offers the most desirable place for thousands of Box Elder Bugs to cluster together and increase their chances of survival. They literally follow the heat into the smallest cracks and voids to hibernate.
High-Risk Zones: Where Box Elder Bugs Hibernate
In Salt Lake City, Box Elder Bugs seek dry and protected spaces that are safe from snow and ice. They do not burrow into woods; instead, they squeeze into cracks.
1. The Gable And Attic Vents
These pests are excellent climbers and will follow the warm walls all the way to the top of your house. They will cluster near attic and roof vents, pushing their way through screens that are even slightly damaged. Since heat rises, the space beneath the roofline and in the attic is often the warmest part of the home. This makes it an ideal hibernation spot until spring.
2. South-Facing Window Frames
The spaces around windows and doors on the south side of the home are critical entry points. As the sun beats down, the sealant around older windows can shrink or crack. This gives the bugs easy access to the narrow space between the sash and the frame. Once inside the wall cavity, they can find their way into your living room or kitchen.
3. Rock Foundations And Porches
Many established homes in the valley have basements or porches with rock or brick facades. The mortar joints between these materials can deteriorate over time. This can create thousands of tiny cracks for Box Elder Bugs to come through. They will often cluster heavily in these areas, especially where landscaping is dense and protects the insects from wind.
What Not To Do When Box Elder Bugs Invade
These pests are driven by heat. So, it is important to be mindful of certain actions that can make the problem worse for Salt Lake homeowners:
- Do not squish them. Doing so will cause them to release a pungent chemical odor, which is their defense mechanism.
- Do not spray them with household insecticide.
- Do not seal too early. If you seal the cracks before treating the exterior, you trap the migrating bugs inside the wall voids.
