Sorry Ames,I never tried those pellets before, so I can not answer your question. I would suggest looking carefully to see anything moving. Maybe, you can zap the pellets in the Microwave, to kill any unwanted hitchhikers, then cool and use the pellets as needed. Avoid other household plants. Just today,i noticed spidermites on my mother’s gardenia plant. You can tell if there is some kind of web around the leaves, and tiny dots moving along them. Like I said they are teeny tiny and they stick to the leaves and stems very well and don’t come off with soaking, thereby making them very difficult to check.
