Sorry.

I'll make it up. I had bug issues early in my move to Washington, so moist here lol. I bought the cheapest potting soil I could find that was supposedly sterile. I didn't spray the crevices of my grow rooms, nor the intakes.

Well I had bugs big time. The drainage from watering had creepy crawlies even.

Off to Fox Farms soils. That made a big difference, but once the bugs got to the soil it was all over. I took a risk and sprayed (early in the flowering cycle so it would decompose) Sevin directly on the top of the soil. DO NOT spray on the plant it will kill it!

While I was at that I used the Sevin in all the cracks and crevices of the room (and I do so once a month or so now) and sweep out all webs and really clean good once a month. I sprayed the intakes at both ends with a lot of Sevin.

I put those sticky fly trap tape things at the intakes and an additional in each room. I keep them fresh all the time. Amazing how many bugs the intakes get.

Once I got all that done and got rid of the bugs I did not have to spray the soil again. (NOT a good thing to do and make sure it gets 2 weeks before harvest so it will decompose.) I have been bug free for 5 years now and last summer the spider mites were the worst ever, I had neighbors loose all their shrubs!

Again, caution with the SEVIN, wear gloves and a mask - it is bad stuff.
