Some bugs make surprisingly good roommates. Spiders, for example, can act as natural pest control while mostly keeping to themselves. Others, however, are destructive invaders—nesting in food, clothes, or even the walls of your house.
One such pest is Phereoeca uterella, a moth that thrives in tropical climates and has an unusually broad diet. Known as kamitetep in Javanese, this wall-clinging insect feeds on everything from wool and silk to dust and paper. As summer heat and humidity rise, spotting their presence early can save your home from damage.
Plaster Bagworms or Household Casebearers?
Kamitetep belongs to the moth family Tineidae. Officially, it’s called Phereoeca uterella. Commonly, you’ll hear them referred to as plaster bagworms or household casebearers.
Here’s where it gets confusing: some experts argue that “household casebearers” are actually a different species (Phereoeca allutella), while others treat the terms as interchangeable. Regardless of the classification debate, no homeowner wants either species lurking on their walls.
