Boxelder bugs are nuisance pests. They do not sting or transmit disease, and are generally not known to bite, though there are rare reports of defensive biting. Boxelder bugs are not known to cause damage to homes or significant damage to plants. However, their feces can stain light colored surfaces. Smashing them can also release an unpleasant odor. They are often found in homes and on the sunny exterior sides of buildings. During the spring and summer, boxelder bugs feed and reproduce on female (seed-bearing) box elder trees. Occasionally, they may also feed on male box elder, maple, ash, and some fruit trees. This can sometimes result in minor deformities in fruits and leaves or yellow leaf discoloration. As winter approaches, boxelder bugs seek out shelter from the cold. They can fly up to two miles to find a suitable location in tree stumps, under debris, or within homes. There they remain mostly inactive until the early spring when temperatures begin to rise.

Control tips:

  • Boxelder错误有时会混淆other similar looking insects. Consider contacting your合作延期服务for proper identification.
  • 如果Boxelder错误在您的家中,请考虑将其吸尘并迅速设置袋子。真空袋也可以冷冻过夜以杀死里面的虫子。
  • 在您家中发现的Boxelder虫子也可以用手挑选或扫除并在户外丢弃。
  • Boxelder bugs do not reproduce inside homes, but find their way inside through windows, doors, ceiling lights, soffit and dryer vents, outdoor faucets, and along siding.
  • 考虑填缝或密封在您家周围的任何裂缝和裂缝,并安装屏幕和天气剥离以排除Boxelder错误。
  • Wood stacks, leaf and rock piles, and overgrown plants near your home may provide shelter for boxelder bugs. Consider removing them.
  • 考虑用水从家外部洗箱虫。Boxelder虫子,特别是年轻人,可以淹死。
  • Their primary food source, female (seed bearing) box elder trees, can be removed. If desired, male box elder trees (non-seed bearing) can be planted in their place.
  • If you don't want to remove female box elder trees, consider keeping the ground below free of fallen seedpods.
  • 如果您选择使用杀虫剂,try alower toxicityproduct first, and be sure tofollow the label.

Through its county agents, the Cooperative Extension Service gives individuals access to the resources at land-grant universities across the nation. These universities are centers for research in many subjects, including entomology (the study of insects) and agriculture. Each county within the United States has an Extension office, which is staffed with agents who work closely with university-based Extension specialists to deliver answers to your questions about gardening, agriculture, and pest control.
