Hoping for some clarification on why these dichlorvos strips are not recommended for use in food preparation areas / food prep items if the vapors leave no residue? Is it the case that there is a temporary residue that dissipates fully over time? We ask because we want to treat almost all of our belongings (including cookware, kitchen appliances, baby clothes and items, undergarments, etc) once they are moved into a separated rented storage unit that we have well sealed. We are planning to air the unit out by opening the garage entrance for several hours a day for 1-2 weeks, and then keep our belonging in storage for additional weeks as needed, airing then out for 3-4 hours more once each week. Approximately how long should we keep this up (we understand the answer may be a range) if we want to be sure ALL vapors and residues have COMPLETELY dissipated and our items are safe for all types of contact again without needing to be washed one by one? We do not feel comfortable with residues/vapors of any level on any our belongings and are willing to go to extra lengths to ensure that. Thank you.
Nuvan ProStrips work best in enclosed areas and will not be opened for an extended amount of time ranging from 2 weeks up to 4 months depending on your target insect(s). Airing the storage unit out daily or weekly for several hours a day would NOT be necessary and not advised as this will allow the vapors to escape and slow down the treatment process. The Nuvan ProStrips should be hung in open spaces to allow airflow to circluate around the strip and kept away from light sources or windows (if applicable). You should use one 16gram strip to treat up to 100-200 cubic feet or one strip per enclosed container. If more than one is required, distribute them within the space equally. Keep the space closed. Once you’ve allowed enough time for the Nuvan Pro Strips to treat the items in the enclosed area, that is when you will want to ventilate the storage unit for a minimum of 2 hours. The manufacturer does not mandate, recommend or state that items need to be washed before use therefore this would be up to your discretion and prefrences. Nuvan Pro Strips can be used in cupboards but not in open areas where raw food is stored, prepared or served and do not allow strips to contact cookware, dishes, utenstils per the manufacturer. We do not have any specific information on this restriction or effects therefore we would suggest contacting Amvac directly at at 888-462-6822 for assistance. Nuvan Pro Strips do not actually provide any type of “residual”. Once the Nuvan Pro Strips foil package is opened, the vapors will start acting quickly on the labeled insects but also begin to degrade rather quickly making this actually a non residual product. It is the slow release of DDVP over time for up to 4 months that provides the “residual” type product. View the full product label for information if needed.
