Hello. Today I completed your initial pest control service. Upon inspecting your home and the records of your pest activity, the carpet beetles are likely to be coming from outside, considering they are adults. I was unable to find a source at this time. I treated your cracks and crevices in the unfinished basement, office, bedroom, playroom, kitchen and entryways and exterior foundation with a non-repellent liquid solution, targeting ants, spiders, beetles, and other general pests. Please allow two weeks for the treatment to take full effect. If you have any questions or concerns, please contact customer service. Thank you for choosing Greenpest solutions.
