What are Symphylids?

Symphylids are small cannabis pests that are tan to white colored and look like centipedes. They are very deadly to cannabis plants because they burrow down into the soil and cause extensive damage by feeding on the roots.

With that, the leaves of your cannabis plants will begin to die off. Symphylids are found mostly in soil composites that have not been cleaned, like soil that has additives in them such as animal manure.  It’s quite easy to tell if you have symphylids because they come to the topsoil when your plants are being watered.

How to Get Rid of Symphylids in Cannabis

I know it will sound (and smell funny!) but sterilizing the soil in the oven for 30 minutes can kill any symphylids and other marijuana bugs in the soil. Heat to 350℃ for 30 minutes. Also, if you have or can find them at your garden supplier, use a fungus gnat killer containing a non-chemical biological control agent like Bacillus thuringiensis (Bt for short) in powder form. One application should kill symphylids but just to be safe, repeat every 7 days to kill off the larvae. Tobacco juice and nematodes kill symphylids as well and are very good alternatives if you can’t find Bt.

Emma BakerGreat company! I was about to kill all my plants and shut down because of frustration with two-spotted spider mites and broad mites. So happy Ryan verified this through a Dino lite microscope at 220 x magnification. Extremely satisfied in his service, my mites died, no eggs spared.

Paul EvansAnt & Garden Pest Control deserves 10 stars saved me from bankruptcy. I had root aphids in my indoor garden there’s nobody that knows how to kill them and has posted it on the internet. Ryan has dealt with them before and knew exactly which olcc approved products to buy and how to prevent reinfestation. I just harvested my first pest free crop in years! I am now going with his maintenance sprays 1 time a week Ryan has all the best lab grade equipment and knowledge. Easier to let him focus on my pests my time can be spent growing bumper crops of exceptional quality. This harvest I yielded 50% more than normal and sold everything I grew for 30% more than last time. Not only are my pests gone but Ryan’s service made me money.

Michael WrightThe commercial-grade soil baggage compost I used for my plants has root aphids. I had to reach out to Ryan of Ant & Garden Pest Control for assistance. The last three months have been quite pleasing as the destructive aphids were gone. Ryan was reliable, providing a constant level of quality with strong results. You can’t beat the peace of mind he offers. I had my first harvest smoothly with his maintenance spraying. We yielded over 2 grams a watt, nearly double our personal best.
