Want to Stop Spider Mites and Broad Mites Before They Start?

If you’ve dealt with mites before, you know how this goes: the damage shows up fast, the webbing follows, and suddenly you’re in full-blown rescue mode.

Amblyseius andersoni sachets are how you stay out of that cycle.

These slow-release sachets deliver consistent, preventative coverage against spider mites, broad mites, russet mites, and more—especially in grow environments that won’t commit to one temperature or humidity level.


Amblyseius andersoni Sachets

Preventative Control for Spider Mites, Broad Mites, and Russet Mites

Each sachet releases all life stages—eggs, juveniles, and adults—over 2–4 weeks. That steady release gives you continuous protection before mites have a chance to build momentum.

Unlike more climate-sensitive species like persimilis or swirskii, Andersoni thrives in the real world—where tents run hot one day and cold the next, and humidity doesn’t always behave.


What It Prevents

Mite Type Early Signs You’ll Avoid
Spider mites Fine webbing, stippling, leaf speckling
Broad mites Twisted or hardened new growth
Russet mites Bronze, rough-textured leaves
Cyclamen mites Deformed growth at crown or leaf center
Eriophyid mites Unexplained blistering or leaf curl


Andersoni is one of the few predators that targets all of the above—making it your best option for broad-spectrum prevention across mite types.


Why These Sachets Work for Prevention

This is your set-it-and-forget-it solution to prevent spider mites and broad mites from setting up shop.
