The answer to 'how long does stink bug treatment last' is that a typical stink bug treatment will provide effective control for 2-3 months. Stink bugs are persistent pests that can quickly re-infest a home, so regular treatment is often required to keep them under control. The length of time a treatment lasts can vary depending on the severity of the infestation, the treatment method used, and environmental factors like weather.
For a severe stink bug problem, a professional pest control company may recommend monthly or quarterly treatments to maintain control. They will use a combination of insecticide sprays, baits, and exclusion methods to eliminate the existing population and prevent new stink bugs from entering the home. DIY treatments like insecticide sprays or traps may only provide temporary relief and last 4-8 weeks before needing to be reapplied.
