They can spread slowly, nonetheless invade the intire collection. keep them seaparted from other plants and try spraying with methylated spirits

I put the 2 in the bathroom away from everyone else. Changed the soil. What Is methylated spirits?
And thanks !

did i say that!!!! i meant use a cotton swab dipped in alchohol and remove them with that

Growing wacky weed in your spare time, teen? Lololol

A plant of mine was infested about 3 years ago. It was severely neglected. I just removed all dead material and sprayed them all off with a somewhat powerful hose and didn't stop until I saw no more. They never came back.

Pls stop repotting the plants, likely you're taking the mealy bugs w/ you to each new repotting.

Don't know whose advice you've been following, you need to treat the mealy bugs to get rid of them. Alcohol swabs or a systemic are the remedies to use.

TG is incorrect in saying they spread slowly, they can actually spread quite fast indeed.

Are you quite sure it's mealy bugs, do they look like cottony fuzz? A pic would say for sure.

Continue to isolate the infested plants. I would use a systemic pesticide as pirate_girl recommended, try mixing something like imidacloprid granules into the soil. It's aborbed by the plant tissue, makes the plant unpalatable to pests, and should work for 6-8 weeks.

You must make sure that, if you do use systemics, they are explicitly labeled for indoor container use.

My favorite mealy bug control is a solution of one part alcohol to three parts water and applied liberally and frequently with a spray bottle. It will get into the folds and layers of the plant.

Good tip Rhizo on the systemics and also the sprayer. So the solution doesn't dry up the foliage?

Sleeper, rubbing alcohol is pretty mild on plant tissue. Isn't it rubbed on a baby's butt before vaccinations? Or your arm? That's full strength, not diluted.

It can't be used on every kind of plant, but spider plants tolerate it just fine.

A staghorn is a fuzzy air plant texture. tissue that's meant for extracting water from the air so I'm not sure how comfortable I'd be just spraying it down liberally. However if I'm just being silly,..please correct me!

...Can't help wondering what the solution would do to scale.

Spraying with soapy water can also help

I've gotten mealybugs under control with alcohol on regular jades, but I'm not sure it would be effective on anything with a lot of crevices. For other plants, I've been successful with holding the plant over the sink and blasting the plant clean with a spray bottle of regular water. Be sure to turn the nozzle so it's a jet, not a mist, and get into all those nooks and crannies. Do this once a week until all evidence of pests are gone. I've also misted plants with soapy water (about a tablespoon of Method dish soap to 10 oz of water, I'm guessing) in a spray bottle between the jet treatments. This combination of treatments worked better than the alcohol.

Still, there are some plants that just seem permanently infested. I have three plants that have been consistently quarantined for about four months. They just keep popping up.
