Interesting - that must be a lot of lava rock! May I ask where you got it? Online the prices & quality fluctuate all over the place

It is indeed.

That said, good luck trying to find exactly what's in it

You don't say that you have actually tried the two applications 24 hours apart. I assume you have, as you are dismissing the possibility of it working? They do suggest weekly or fortnightly applications afterwards to catch the next generation for full eradication. I am dismissing it because I know ...

If you have serious fungus and/or insect problems and are serious about eradicating them, go on a PA1 pesticide spraying course.

You will then have the the freedom to use professional products.

How else are nurseries able to grow such good specimens? It's not by accident

Yes but with cacti especially there are so many nooks & crannies where mealies hide that it's pretty much impossible for a product like SBPI to work effectively.

Unless you get every single one, including eggs, they will just breed and appear again.

Dehumdifier pads will eventually become saturated, so you'll have to 'dehumidifiy' the dehumidifying pad. All a bit of a pain. You might be better off just using fans 24/7 to circulate the air. Alternatively, the best (but most expensive) option is to run a dehumidifier 24/7. I've been using a Meaco...

Very nice, you can't beat small cacti with big flowers

Not much use to the rest of us... Useful to me as I have a licence too. As an amateur grower, pests & disease are by far the #1 problem in growing cacti. Growing cacti & other plants means everything to me, it's my obsession so I've found the time and expense acquiring the licence is well w...

Very pleased to see this Steve Brack plant flower for the first time today. I wasn't expecting it to flower - ever - given the low light levels we get compared to its habitat.
