The American Roach is an African native that migrated to the states around 1625. It is considered the second most popular Roach beside the German cockroach. They are larger than their German brethren and tend to live in moist areas.
The odorous house ant typically does not have any smell. But when step upon they will emit an unpleasant odor similar to rotten coconuts. These ants will often invade your home looking for food and then settle within your walls or floors.

The ghost ant is an extremely small, translucent and pale in color insect that tends to vanish against its background, hence its name. They often gravitate toward locations where larger amounts of water are located. Their appearance can also suggest a moisture/water issue within your home.
