Wow, that actually makes sense.
I’m pretty sure these things came out of the seed itself.
When I first noticed them, they was all huddled together in the seed shell.
Any ideas on how to get rid of them?
I sprayed them with Pyrethrin, but it didn’t kill them all which is something I’m not used to.
I thought Pyrethrin killed all insects.
I really appreciate all the advice. I will definitely use some mosquito bits to treat the soil for any potential eggs or larvae.
You guys rock!
The problem is that the adults laid eggs inside the seed when it was soft and developing still. By then, it is already too late (for the next generation of the plant, anyway).
Pyrethrin kills a lot of insects, but I would recommend against it outdoors, as it hurts bees and other pollinators, where they bring it back to nests and wipe out everything.
Mosquito bits are corn kernels soaked in BT, a species of bacteria that kill the larvae of insects. While it might work to water an infected seed with BT to kill the larvae before they turn into adults with legs, I think by then the plant embryo would be too damaged.
Also, BT has a few different variants that target specific types of larvae. Mosquito bits contain the “israelensis” sub-species, which target the larvae of some very small flying insects like mosquitos and fungus gnats. The other common variant is “kurstaki” which targets large larvae, like caterpillars. Once they are no longer larvae, BT has no effect, making it a safe option in the garden, keeping the beneficial insects around in the soil.
Anyway, if you have weevil eggs in your seeds, I’d toss those seeds and get new ones…it’s not worth the trouble. They are a known cannabis pest.
All good points @resimax thank you.
The plants I sprayed are indoors. I would not spray outdoors because of the bees. But I should have also warned about cats and Pyrethrin. It can be harmful to cats, so please keep that in mind.
While the mosquito bits may not kill any weevils , it’s part of my ipm anyway. I have fungus gnats as well.
I agree, I should dispose of the seeds.
I started three seeds from the same pack. Only one seed has the weevils.
If you want to save some money, get this and thank me later:
The 2oz for $20-something will last you years. It’s concentrated BTi…made for large ponds and ditches. You only need like 1 drop for a few gallons of water. The directions state 6 drops for 100-gallons of water. For the garden, 1 drop for any amount of watering is more than enough. I usually put in 2 or 3 for good measure, and my 2oz bottle is 2 years old now, and still full 
Also you don’t need to steep it like you do with mosquito bits.
Excellent. Thanks a ton
The bits seems to lose their effectiveness after a while. This should work better and sounds like it has a long shelf life. Win win.
I added it to my Amazon shopping list and I took a screen shot of your directions for use. Thanks again.
very true, although spider mites are satan so its an easy to see why that is 
does that microbe lift work on spider mites? I got these fuckers carrying them in
horrible little fuckers.
