Amblyseius Cucumeris Prevention Sachets
Amblyseius Cucumeris Prevention Sachets
Amblyseius cucumeris Sachets provide preventative pest control for thrips larvae and several mites on houseplants. Each sachet contains live Amblyseius cucumeris in all life stages—eggs, juveniles, and adults—that emerge over time and feed on small, soft-bodied pests. This fixed-release tool delivers 3–5 weeks of coverage before replacement and does not establish long-term populations in your crop. Because cucumeris feed on the larval stage of thrips—not adults—these sachets are designed for prevention rather than rapid knockdown of active outbreaks.
For use, place 1 sachet per plant for individual plants; 1 sachet every 6 feet for a preventive perimeter; and 1 sachet per plant or every 3–4 feet on high-risk crops. Start sachets 5–7 days after bottle release and replace every 3–5 weeks. Do not open the sachet; hang near foliage above the watering line and keep out of heavy mist zones or direct irrigation. Best conditions are 66–80°F with moderate to high humidity, and they are suitable for both natural and artificial grow lights. If conditions are dry or variable, consider a Plus style sachet for improved release consistency.

Let customers speak for us
from 71 reviewsReally nice soil and awesome service
Never used because I ordered the wrong Water Filter. Mike was very helpful with the return and refund. Excellent Customer Service.
Great service. Soil is what I wanted and it off loaded exactly where I asked.
Plants are doing really well with this soil. Deep and rich looking soil, plants seem really happy. Much more cost effective (and no plastic bag waste) compared to buying bags of soil mix from a store.
Thank you for shipping so soon. Great service
The quality of the craftsmanship is superb! My formula one fan absolutely loves it!!!!
Worked like an absolute charm!
These markers were perfect for ones that we were replacing. The quality is great and they seem sturdy. The gold detail stands out and is visible from a distance. Shipping was very fast.
Good solution. The little flies have disappeared. We were sure to mist/moisten the surface of each plant once a day for 4 or 5 days, after the initial application of the nematodes, to keep the little guys mobile and able to get to any remaining eggs. So, go for it!
Plant was well packed and shipment was very fast. Received a very nice fully rooted plant in the pot!
The organic garden soil is doing very well in my garden bed. The company was professional, nice, and accommodating to my needs. They provide many types of things for your landscaping at a reasonable price.
Product was delivered promptly and the quality of the product was very good, as hoped for. I was thrilled to receive the product so quickly! Thank you!
Product is great. Didn't care for having to pay am extra $17 tariff to UPS to get it delivered, but I guess that's not your doing. Thank you Mr. President.
