Delaware is now part of a federal investigation after residents reported being sent mysterious packages from China with plant seeds and other inexpensive items in them. Officials say about 20 residents have reported that they were sent these items but never ordered them. According to reports, the seeds are likely part of a brushing scam which is when shippers send out low-cost items at their own expense in order to rank higher on e-commerce sites and brushing helps the seller create a more legitimate appearance on their profiles. Officials say if you received a package with seeds leave everything inside the envelope and report it to the Smuggling Interdiction and Trade Compliance Program by calling the Smuggling Hotline at 1-800-877-3835
