Final answer:
The two insects that infest and feed on upholstery and feathers are the clothes moth and the carpet beetle. Prevention and control methods are vital to protect household items from these pests. The correct answer is c) clothes moth and carpet beetle.
Step-by-step explanation:
The two insects that feed on upholstery and feathers are the clothes moth and the carpet beetle. These insects have larvae that are particularly known for consuming materials like wool, silk, fur, and feathers, which can be found in household items such as clothes, carpets, and upholstered furniture.
Clothes moths and their larvae often reside in dark, undisturbed areas where they can feed on these materials without being disturbed. Similarly, carpet beetles can cause significant damage to fabric-based items by feeding on them during their larval stage.
It is important to manage and prevent infestations of these pests to protect your household items. Measures include regular cleaning, storing items in airtight containers, and using pheromone traps or insecticides if necessary. By understanding the habits and life cycles of these insects, we can better prevent and control their populations.
