The difference between beetles and roaches is that beetles are much more advanced insects.
The dissimilarity seen with the naked eye is that beetles have a hard outer covering on their wings.
All these insects really have much in common, but, of course, the differences between them exist.
Obviously all these pests have many common features: their size (from 30 to 50 mm in length); dark color from reddish brown to black; wide and glossy body.
And their living habits are much alike as well: they all tend to live in Palmetto trees (that is where the name “Palmetto Bugs” comes from).
You will not enjoy your life in Florida if you can’t stand these insects.
If you take the efforts, at least their penetrations into your house will be less frequent.
To do that close all the ways the pests can use to enter your house.
The Palmetto Weevil is a rather small black and red beetle with a long snout.
And it has nothing common with anything what may be called a Palmetto Bug.
