How to Get Rid of Boxelder Bugs: Easy Ways to Keep Your Home Bug-Free

Understanding Boxelder Bugs

Boxelder bugs are members of the Coreidae family that also includes stink bugs and cicadas. These are insects of the order Hemiptera but are also referred to as the ‘true bugs’. Although they resemble certain other insects, people can distinguish boxelder bugs.

Physical Characteristics

Boxelder bugs are easily recognizable due to their distinct appearance:

• Color: They have all black bodies, with red-orange patches on their thorax and forewings, which are the most identifying feature.
• Size: Boxelder bugs that are adults are approximately 1/2 inch (12-14mm) long. They are so small that people won’t notice them the first time, but they are very irritating when they congregate in masses.

Habitat Preferences

Boxelder bugs follow a strict feeding and nesting pattern:

• Feeding Habits: They feed mainly on the seeds of boxelder, maple and ash trees that keep them going.
• Winter Habits: Boxelder bugs seek a warm place to settle when the weather becomes cold during the fall. They prefer to go indoors into houses, buildings, and other warmer places not exposed to weather conditions.

Behavioral Traits

Boxelder bugs are especially annoying because they have behaviors that make them hard to control.

• Indoor Migration: Boxelder bugs initiate their indoor migration in late fall, and they enter indoors utilizing cracks and crevices around windows, doors, and vents. Once inside, they are attracted to the warmth and become a problem inside.
• Odor Emission: The bugs can have a foul smell when they are crushed and this is one of the reasons that residents always want them exterminated. This defense mechanism is intended to protect against predators; however, it also causes discomfort to the homeowners.

1. Identify a Boxelder Bug Infestation

Boxelder bugs can be spotted easily as they seek warmth inside houses in the fall and winter. This may become an infestation.

Visual Indicators

The first signs of infestation with boxelder bugs should not be overlooked since it could make the situation easier. The following are some things that should be looked at:

• Clusters of Bugs on Sunny Sides of Buildings: Boxelder bugs tend to gather in large groups, especially on the warmer sides of buildings. They prefer being warm and hence during the fall, they congregate in large numbers on sun facing exterior walls.
• Presence Near Windowsills, Doors, and Attics: People may discover bugs near windowsills or the frame of doors. These are the points where the bugs enter a home. This is where they come seeking protection and shelter. 

Signs of Infestation

When on the inside, boxelder bugs will show several traces that they reside there:

• Small Black Stains or Spots (Fecal Matter): The fecal matter of a boxelder bug is the tiny black stains or spots that they leave behind. These marks can be found on window sills, walls and other areas where the insects clustered together.
• Visible Damage to Trees: Boxelder bugs eat the seeds of trees, such as boxelders, maples, and ash. They usually do not feed in a way that harms established trees, but will cause leaves to discolor or branches to die by feeding on them. Excess boxelder insects around the base of a certain tree are also indicative that the tree may be serving as food to the bugs.

Seasonal Patterns

One of the traits boxelder bugs exhibit is that they show decidedly seasonal behaviors that can help identify their presence:

• Increased Activity During Late Summer and Fall: Boxelder bugs become more active during late summer and fall, as they forage for food & warmth. They then move from trees into houses, looking for openings and cracks to gain entry.
• Reduced Visibility in Winter: Boxelder bugs enter a hibernation state while indoors during the winter. They are less noticeable because they live in attics, wall voids and other remote places. However, they can still be hiding away and will be more active later in the spring as temperatures rise.

2. Use Effective Methods to Remove Boxelder Bugs

Here are several ways people can keep boxelder bugs away from the home, using a combination of traditional tactics, chemical methods and natural solutions to reduce the infestation.

Manual Removal

One of the easiest and fastest ways to deal with boxelder bugs inside the home is manual removal. Some effective methods include:

• Vacuuming: A vacuum works fast on removing the boxelder bugs. It dislodges the bugs off the walls, windowsills and other smooth surfaces without making them scatter away or cause a mess to happen.

Natural Remedies

There are a couple of natural ways that allow people who wish to eradicate boxelder bugs to do it in an environmentally friendly manner.

Chemical Solutions

Fall and winter are the best seasons to be proactive in preventing and controlling boxelder bug infestations to ensure the most success. Here are some of the recommendations:

Pre-Fall Preparations

Before the cool autumn months set in, being proactive can greatly reduce the likelihood of a boxelder bug infestation:

• Inspect and Seal Potential Entry Points: In late summer, survey the house for entry points such as cracks, gaps, and broken screens around windows, doors, vents, garages, and the foundation. Seal any openings with caulking or weather stripping to avoid allowing the bugs inside.
• Trim Trees and Remove Debris: Boxelders are attracted to trees for food and shelter. Eliminate any branches that come too close to the house, and clear any fallen leaves and debris in the yard. This will significantly reduce the likelihood of the bugs entering the home in search of a warmer spot.

During Fall

Autumn is the time when boxelder bugs are most active and looking for entry points into the home. Here are some tips:

• Monitor for Early Signs of Infestation: Look for clusters of boxelder bugs on the sunnier sides of the house and near the areas people would expect them to enter. The moment you observe an exceptionally great number of the insects, they act fast.
• Apply Preventive Treatments as Necessary: If boxelder bugs often infest the living space, using natural repellents or insecticidal treatments around the previously determined entry points may discourage the insects from forming an infestation.

• Maintain Indoor Cleanliness: Regularly vacuum and cleanse the areas where the bugs collect, such as windowsills, door frames, and attics. This will discourage the pests and prevent the situation from spreading further.
• Address Any Indoor Sightings Promptly: If the boxelder bugs reveal themselves in winter, act quickly. Use a vacuum or sticky tape to catch and remove them from the living space manually. Do not squash the bugs, as they will release an odious stench.
