Western Boxelder Bug
A red and black bug very similar to the eastern boxelder bug but found in western North America. It forms large overwintering aggregations on buildings and fences near boxelder trees. It is a nuisance pest but causes no structural damage.
Did You Know?
When crushed, it stains fabrics and surfaces with a reddish-orange dye from its body fluids, which is why it should be vacuumed rather than squashed when found indoors.
Warehouse Beetle
A stored product beetle closely related to the khapra beetle that infests grain, cereals, and dried foods. Its hairy larvae contaminate food products and can cause allergic reactions.
Did You Know?
It is so similar to the quarantine-regulated khapra beetle that expert identification is needed to tell them apart.
