Your house will likely be filled with strong, unpleasant fumes after fumigation. The best way to get rid of these fumes is to air out your house. Ideally, you should leave your windows, connecting doors, and fans open for at least 3-6 hours to allow your house to air out.

However, you can keep them open for longer if you notice that the smell isn’t going away. This issue may happen if your house does not have a proper ventilation system. In places like this, it can take up to 1-3 days. Air out your house as often as possible. After fumigation, you’ll want to continue to air out your house for as long as the smell lingers.
