Boxelder trees produce the seeds that these pests feed on, hence the name. Fortunately they will not bite or sting. However, they can stain carpet and other fabrics. After they are found dead from exposure to our pest control product, be sure to sweep or vacuum them up before you accidentally step on them. If smashed, they will release a fowl odor, and create a stain mark on wood, cement, or other household features. ...Gross!
