The onset of autumn brings a plethora of changes, from the vibrant hues of changing leaves to the influx of various insects seeking shelter from the impending cold. Among these, the boxelder bug stands out as a common nuisance for many homeowners. These flat, oval-shaped insects, typically around 1⁄2 inch long and characterized by their red or orange coloration with black wings, are not harmful but can be a significant nuisance due to their tendency to invade homes in large numbers. Understanding what attracts boxelder bugs is crucial for effective prevention and management.
Boxelder bugs are primarily attracted to the seeds of the boxelder tree (Acer negundo), from which they derive their name. However, their attraction is not limited to these trees alone. The bugs are drawn to a variety of factors, including:
Food Sources: Beyond the seeds of boxelder trees, these bugs feed on the seeds of other maple trees and can be attracted to gardens with an abundance of seed-producing plants. They also consume aphids and other small insects, which can be found on a wide range of plants.
Warmth and Light: As the weather cools, boxelder bugs seek warmth and light, often finding their way into homes through any available opening. South-facing walls and windows, which receive direct sunlight, are particularly attractive to these insects.
Moisture: Like many insects, boxelder bugs are attracted to moisture. Areas around homes with poor drainage, leaking gutters, or where the sprinkle system creates persistent dampness can attract these bugs.
Shelter: The primary motivation for boxelder bugs to invade homes is the search for shelter from cold temperatures. Cracks, crevices, and any opening in the structure of a building can serve as an entry point.
Given these attractants, preventing boxelder bugs from invading your home requires a multi-faceted approach that addresses their nutritional, environmental, and shelter needs. Here are some effective prevention tips:
Seal All Entry Points
- Inspect and Seal Cracks: Use caulk or weather stripping to seal cracks around windows, doors, vents, and any other potential entry points. This is the most critical step in preventing boxelder bug invasions.
Eliminate Attractants
- Remove Seed Sources: If possible, remove or trim back boxelder trees or other seed-producing plants near your home.
- Manage Gardens: Keep your garden free of debris and weeds that might attract aphids or other small insects that boxelder bugs feed on.
Reduce Moisture
- Fix Leaks: Ensure that your home’s gutters are clear and functioning properly to direct water away from the foundation.
- Improve Drainage: Modify your yard to improve drainage if necessary, to prevent water from accumulating near your home.
Use Deterrents
- Essential Oils: Certain essential oils, such as peppermint, lemongrass, and lavender, can repel boxelder bugs. These can be used in diffusers or mixed with water and sprayed around entry points.
- Diatomaceous Earth: A natural, non-toxic substance that can dehydrate and kill insects. Sprinkle it around the perimeter of your home and in gardens.
Professional Assistance
In cases of severe infestation, it may be necessary to consult with a pest control professional. They can provide targeted treatments and offer additional advice tailored to your specific situation.
Conclusion
While boxelder bugs do not pose a significant threat to human health or property, their invasions can be a significant nuisance. By understanding the factors that attract these bugs and implementing effective preventive measures, homeowners can reduce the likelihood of an infestation. Remember, prevention is key, and addressing the issue before it becomes a problem is the most effective strategy.
