This species was intercepted 16 times on a variety of hosts at U. S. ports-of-entry between 1995 and 2012, with specimens originating from Colombia, Costa Rica, Dominican Republic, Puerto Rico and St. Lucia. We also have examined specimens taken in quarantine from Barbados (Annona); Brazil (Laurus, Thymelacaceae); Costa Rica (orchid); Dominican Republic (Annona); Jamaica (Begonia); Puerto Rico (Dieffenbachia). ScaleNet includes hosts in only 7 plant families. ScaleNet distribution records for P. vitreus include several countries in the Neotropical zoogeographic region and The United States of America (Florida) in the Nearctic region. No other species of Pseudokermes have been intercepted at a U. S. port-of-entry.
