The answer to 'how long does bed bug treatment last' is that the duration of bed bug treatment can vary, but it typically takes several weeks to fully eliminate an infestation. Bed bugs are notoriously difficult to get rid of, and a single treatment is rarely enough to completely eradicate them.
In most cases, a professional pest control treatment will need to be followed up with additional treatments over the course of 2-4 weeks to ensure all bed bugs and their eggs are killed. The exact number of treatments required will depend on the severity of the infestation and the effectiveness of the initial treatment. Homeowners should be prepared to work closely with their pest control professional to monitor the situation and schedule any necessary follow-up treatments.
