Did You Know?

1. Despite their intimidating appearance, boxelder bugs do not bite humans. They possess a proboscis designed for feeding on the sap of boxelder trees, not for biting or puncturing skin.

2. Boxelder bugs are part of the true bug family, known as Hemiptera. This classification is due to their unique mouthparts, which are adapted for piercing and sucking fluids.

3. One fascinating behavior of boxelder bugs is their ability to release a foul-smelling odor when threatened or squashed. This odor serves as a defense mechanism to deter predators.

4. These bugs are known for their aggregating behavior, meaning they tend to gather in large numbers. Masses of boxelder bugs can often be seen clustering on sunny sides of buildings, trees, or other structures during the cooler months.

5. Boxelder bugs undergo a process called diapause during winter, which is similar to hibernation. They find shelter in crevices or structures and become dormant until the arrival of warmer temperatures, resuming their activity and feeding habits.

Boxelder Bugs’ Feeding Habits

Boxelder bugs, scientifically known as Boisea trivittata and Boisea rubrolineata, are small insects that primarily feed on the sap of boxelder trees. They have specialized mouths called proboscis, which they use to pierce the leaves, flowers, and seeds of female boxelder trees to extract the nutrient-rich juice. These bugs can also feed on other trees such as maple, ash, almonds, apple, cherry, peach, pear, plum, and grape.

While boxelder bugs primarily consume plant material, their piercing mouths can sometimes cause deformities or bruises on fruit. This can be a concern for fruit trees when infestations become significant. However, it is important to note that boxelder bugs rarely pose a direct danger to humans. They do not typically bite, and their feeding habits are focused on trees rather than people.

Additionally, boxelder bugs can emit a substance that stains surfaces and emits a foul odor when crushed. The foul odor serves as a defensive mechanism and deters potential predators.

In some cases, boxelder bugs can form large swarms consisting of hundreds or even thousands of individuals. These clusters can be quite unnerving for homeowners, and their presence inside buildings can become a nuisance.

During colder months, boxelder bugs seek shelter in cracks and crevices of homes and buildings, where they may enter through heating systems or when the external temperature increases.

To summarize:

  • Boxelder bugs can leave stains on surfaces due to their excrement.
  • They emit a foul odor when crushed as a defensive mechanism.
  • They can form large swarms that can be unnerving for homeowners.
  • During colder months, they seek shelter in cracks and crevices of buildings.

Boxelder Bugs’ Defensive Mechanisms

Boxelder bugs have developed certain defensive mechanisms to protect themselves from threats. When disturbed or crushed, they emit a pungent odor that can be quite unpleasant. This foul smell acts as a deterrent to potential predators, keeping them at bay. Additionally, boxelder bugs secrete a substance that can stain walls, carpets, and other surfaces. It is advisable to avoid crushing these bugs due to the foul odor and staining potential.

It is worth noting that boxelder bugs are part of the natural ecosystem and serve as a food source for various animals. Rodents, spiders, praying mantises, wheel bugs, chickens, ducks, and guinea hens may feed on boxelder bugs when other food sources are scarce. This natural predation can help in controlling their populations.

Boxelder Bugs’ Habits And Behaviors

Boxelder bugs exhibit certain habits and behaviors that are characteristic of their species. They are attracted to bright spots and sunlight, which is why they may cluster near windows or areas with ample light. As the weather gets colder, boxelder bugs overwinter by seeking shelter in cracks and crevices of homes and buildings, making them a common household pest during colder months.

Female boxelder bugs lay their eggs on female boxelder trees, as these trees serve as their primary food source. The eggs hatch during spring, and the young nymphs go through several molts before reaching adulthood. The lifespan of a boxelder bug can range from a few months to over a year, depending on environmental conditions and availability of food.

Methods For Dealing With Boxelder Bugs

Prevention is key when it comes to dealing with boxelder bugs. Taking proactive measures to discourage their entry and eliminate their food sources can help reduce infestations. Here are some methods recommended by the National Pest Information Center:

  • Professional Pest Control: Regularly enlisting the help of a professional pest control service to spray insecticide twice a year can effectively manage boxelder bug populations.
  • Sealing Cracks: Close any exterior cracks or openings in your home or building to prevent boxelder bugs from entering. Pay attention to areas around windows, doors, and utility openings.
  • Cleaning Surfaces: Clean surfaces, drapes, and carpets with soap and water to remove boxelder bug stains and excrement. This can also help deter their reinfestation.
  • Removing Food Sources: If you have boxelder trees or other preferred food sources in your yard, consider removing or replacing them to reduce the attractiveness to boxelder bugs.
  • Vacuuming: Regularly vacuuming your home can help remove boxelder bugs that have already entered. It is crucial to empty the vacuum bag or canister after each use to prevent their escape.
  • Avoid Crushing: As mentioned earlier, avoid crushing boxelder bugs as they emit a foul odor and can stain walls or carpets. Instead, opt for less invasive methods like vacuuming or using a broom to remove them.

In conclusion, boxelder bugs rarely bite humans and do not transmit diseases. Their feeding habits are focused on plants, particularly boxelder trees, and they can cause some damage to fruit. While they may be a nuisance when entering homes, they can be effectively managed through preventative measures like professional pest control, sealing cracks, cleaning surfaces, removing food sources, and vacuuming. Remember, prevention is key when dealing with boxelder bugs.
