Ok, where do you get this BT at or what is it's trade/marketing name that it goes by. Have fungus gnats too. Not bad, but enough to be pesky

Bacillus thuringiensis israeliensis strain--called Bti.
That's the one that nails fungus gnats..

You Americans are lucky.
You've got "county extension agents" for advice.
Try phoning him or call a farm supply company.

We've got government horticulturists and they're all laid off 😐

I don't have Btor Bti either.

But I noticed today I've got soft-bodied scale AGAIN on a couple of palms 👿 👿
Even AFTER Dimethoate 480.
Maybe I didn't use enough (cough, cough).

Found this application chart for both 3% and 35%(food grade) Hydrogen Peroxide use for plants.

3% is easy to get at any grocery or drug store. 35% may only be found at health food stores where I buy mine. I will say to wear protection on hands and on any surface you plan to add drops, or transfer into bottle with dropper. It WILL burn your skin, and delaminate/discolor most counter surfaces. Also, 35% needs to be stored in freezer, or refrigerator at the very least.

Uses for Hydrogen Peroxide it seems is endless.

Yeah, tons of uses (kinda like WD-10) 😆

Today, I'll be using the Q-tip/hydrogen peroxide on the soft-bodied (beige) scale on the small Brahea armata and Sabal minor.
Same thing for the mealybug on the Cocos nucifera.

Beats the heck out of vacuuming... 😐
