prepping new soil for bugs question

[cyberaktif]

Hello everyone,
I think i'm bringing in thrips from bagged soil I get from the local growers co-op. What does people do with their soil in prepping for bugs? Should I do a soil drench a few weeks before transplanting? Tired of these pesty little guys. I use a soil-less medium, sunshine mix LC1. It has Sphagnum peat moss, perlite, limestone.

I add 3 things to the soil for bugs-they are solids


Neem cake for 5 gal= 60g/2oz (also has an N value of 4-5)

Bti-bits for 5gal= 15g/1 tablespoon (Misquito bits)

Diatomaceous Earth @ 60-75g topdusted

Gnatnix is a one time application- so once in the final pot- I use it to create a bug barrier.

I usually use an inch of sand as a top dressing on my pots.Keeps lots o stuff away. Cinnamon also works well on the soil and as a spray if there on plants.

I will look into all these items. I had a bottle of "captain jack's deadbug" spray which has spinosad in it. That worked really well. I then bought some "monterey insect gaarden spray" and sprayed my plants. I should have read the destructions because my plants were as brown as brown could be. Come to find out it was full strength and didn't know i had to dilute. Brought them ladies right back to good health and flowered them.

Monterey spinosad goes in your soil not on leaves.

so it is just a soil drench then?

Weed Pharma so even with the gnatnix you can pour the water and nute water over the gnatnix?

[Dutchman1]

Put an inch of sand on the top of your pots. The gnats will stop in a week or two.

cyberaktif, yes- pour water/nutes over gnatnix, as it allows for proper drying of the top portion of soil and allowing more oxygen to the roots. - to deter bugs.
Mulch keeps the soil too moist which in turn-attracts more pests.

Have a look at what these guys offer www.arbico-organics.com. They have some great products but might not be right for indoor.
