As long as the Nuvan ProStrips are sealed in a bag and not just sitting out in open living space, they are safe.
Nuvan ProStrips do work well to kill any insects including bedbugs within electronics or items you can't put in a dryer or treat with chemicals like shoes, books, etc. You would need to put the strip in with the item and leave it in an air tight container completely sealed for 2-4 weeks to kill anything within it. It will not harm anything you have in the container but the manufacturer does suggest if you have any leather clothing to keep the strip off the fabric directly and to lay it on something else within the container.
NuVan ProStrips do work in confined areas like small closets. You can leave them in there for 2 weeks to four months for the listed pests. Please let us know if you need anything else.
As Nuvan ProStripes are labeled to be treated for flies we do not recommend using in food handling areas such as kitchens, or in large open spaces where people make occupy for an extended amount of time. Nuvan ProStrips are most effective in confined spaces.
When treating for bed bugs on items with the Nuvan ProStrips the standard treatment time is 2 weeks minimum per the manufacturer but the product label gives information about it lasting 4 months for other pests. If it is a severe infestation some customers feel more comfortable leaving items sealed for longer
You can place books in large trash bags or rubber tubs that have a top with Nuvan Prostrips. Nuvan Prostrips utilize controlled release technology to slowly diffuse a deep penetrating vapor in enclosed spaces. The clean, odorless vapor is evenly distributed throughout the enclosed treatment area, killing visible and hidden insects on contact and preventing new insect infestations. The books do not need to be tightly packed in the bins/trash bags. No, the vapors will not penetrate pages.
Nuvan Prostrips are only effective for up to 4 months. Once that time period has passed, they will no longer be as effective as they were when they were first opened. We recommend changing them out every 4 months to make sure you are getting maximum performance out of the product. Please read the product label for further information.
