Firebugs are commonly known as insects of the Pyrrhocoridae family, which are typically found in gardens and forests. However, there are various other terms used to refer to these small bugs with vibrant red and black coloration. One such synonym is "red bugs" due to their striking red hue. Other names include "cotton stainers" since they feed on cotton plants, leaving behind stained marks. In some regions, firebugs are also referred to as "box elder bugs" due to their tendency to infest the box elder tree. Regardless of what they're called, these little insects can be a nuisance, so it's important to keep gardens and yards maintained to discourage their presence.
