Carpet beetle infestations are less likely to occur in homes that utilize mostly synthetic fabrics. Synthetic carpets, sheets, and clothes will not easily play host to carpet beetles when properly washed. However, carpet beetles can take still take hold in these environments depending on other factors. For example, collected dog hair in the corner of a room or under a couch can become infested with carpet beetles very quickly.
Common places to check for these infestations are under furniture, the bottom of trash cans, ground-level lint traps on HVAC intake vents and in containers holding certain types of animal feed.
