Federal and state officials are sounding the alarm as thousands of Americans report receiving unsolicited seed packets in the mail, an eerie repeat of the 2020 scare that affected all fifty states.
The seeds, mostly shipped from China and other Asian countries, often arrive in unmarked white or yellow pouches labeled as jewelry, toys, or earbuds. Experts warn that planting them could unleash invasive species, plant diseases, or noxious weeds that threaten crops, native plants, and entire ecosystems.
A Problem That Never Really Went Away
The phenomenon exploded in the summer of 2020 when the USDA received more than 80,000 reports nationwide. Investigators later determined most packages were part of “brushing” scams, where third-party Amazon sellers send unsolicited items to real addresses, then post fake five-star reviews as if the recipient had purchased them.
The practice largely died down by 2022. But it never fully stopped.
Since late 2024, reports have surged again. Texas alone has logged more than 1,200 cases in the past fourteen months. Colorado, Alabama, Virginia, Ohio, Kentucky, Louisiana, and Utah have all issued fresh warnings in 2025.
The Colorado Department of Agriculture told KJCT this week they are once again working with federal partners after multiple residents in Grand Junction and across the state received the mystery packets.
Why Officials Are So Worried This Time
Wondirad Gebru, director of the Plant Industry Division at the Colorado Department of Agriculture, explained the danger plainly.
“These seeds bypass all import inspections,” Gebru said. “They can carry insect pests, fungal diseases, or noxious weeds that our farmers and native landscapes have no resistance to.”
In 2020 testing, some packets contained invasive species like dodder, Palmer amaranth, and morning glory variants that can choke out crops and native plants within a single season.
One Virginia farmer who planted “free sunflower seeds” in 2020 spent three years and thousands of dollars eradicating the aggressive weed that took over twenty acres of his soybean fields.
Plant just one packet, and you could accidentally introduce the next kudzu or Japanese knotweed.
What You Must Do If a Package Shows Up
Do NOT open it. Do NOT plant the seeds. Do NOT throw them in the trash or compost.
Follow these exact steps:
- Leave the seeds inside the original packaging
- Place the entire package in a sealed zip-top bag
- Put that bag inside another sealed zip-top bag (double-bagging prevents escape)
- Mail or deliver it to your state’s designated USDA office (Colorado address below; other states have similar drop-off points)
- Report it to your state department of agriculture and to the USDA at stopunsolicitedseeds@usda.gov
Colorado residents should send double-bagged packages to:
USDA APHIS PPQ
3950 North Lewiston Street, Suite 104
Aurora, CO 80011-1561
You can also call Colorado’s Plant Industry Division at (303) 869-9052 with questions.
The Human Stories Behind the Warnings
In rural Louisiana this spring, an elderly couple nearly planted what they thought were free wildflower seeds. Their grandson, a county extension agent, recognized the familiar yellow pouch from 2020 alerts and stopped them just in time.
In Utah, a mother on Facebook shared photos of the “cute earrings” that arrived for her daughter, only to discover seeds when the package was opened. Hundreds of comments poured in from people who received the exact same packets the same week.
These are not harmless freebies. They are unregulated plant material entering the country illegally.
The USDA continues to investigate the source. While many packages appear tied to brushing scams, officials have not ruled out intentional ecological sabotage, though no evidence currently supports that theory.
What is certain: the risk is real, and the cost of inaction could be measured in billions of dollars and decades of environmental damage.
Americans opened their mailboxes to mystery in 2020 and learned a hard lesson. Five years later, those strange packets are back. This time, we know exactly what to do, and exactly why we must do it.
If you have received one of these packets, or know someone who has, share your story in the comments below. Our agriculture and native landscapes depend on all of us staying vigilant together.
