An accepted follow-up practice to a carpet beetle treatment is:

The selection of inspecting and installing pheromone traps as an accepted follow-up practice to a carpet beetle treatment is particularly effective because these traps help monitor for any remaining beetles after the initial treatment. Pheromone traps are designed to attract adult carpet beetles, which can provide insight into whether the treatment successfully eliminated the infestation or if there are still adult pests present that could potentially reproduce and lead to a new infestation.

Using these traps allows pest control professionals to evaluate the ongoing situation in a more proactive manner. If insects are still being captured in the traps, this could indicate the need for additional treatments or different strategies to fully eradicate the carpet beetle population.

In contrast, while the other options might seem viable, they do not provide the same level of targeted monitoring and control. Residential fumigation is a more aggressive approach and may not be necessary after an initial treatment unless there is a widespread and severe infestation. Removing all carpets could be an extreme and disruptive measure that is not typically required for carpet beetle control. Daily vacuuming may help reduce some adult beetles and their larvae, but it won't provide the targeted monitoring that pheromone traps offer. Therefore, using pheromone traps aligns with the best practices for ongoing assessment and management after treatment.
