The answer to 'which is better preventive treatment or reactive treatment' is that preventive treatment is generally better for managing pests. Preventive treatment involves applying pest control measures before an infestation occurs, such as regularly treating for pests or sealing entry points. This helps stop problems before they start and can be more effective in the long run. Reactive treatment, on the other hand, is when you wait until you already have a pest problem and then take action to address it. This can be less effective and more costly, as you're dealing with an active infestation.
The benefits of preventive treatment include reduced risk of a full-blown infestation, lower overall costs, and less damage to your home. Reactive treatment may be necessary in some cases, but it's usually better to take a proactive approach to pest control whenever possible.
