Mealy Bugs

Unluckily, I found two mealy bugs on one of my orchids today. I got rid of them and sprayed the plant w/ the "best stuff ever". Do I need to quarantine that plant from the others for a bit?

akkk!! yes, where you see one, there is a nest somewhere hatching out oodles of the little monsters! search till you find it, and i suggest spraying with a systemic insecticide....kill them quick and take names later.....gl

I fundamentally disagree with this statement.
Going in with the big guns right away is not necessarily a great idea and can lead to resistance.

I would thoroughly inspect all your orchids for any presence of mealies. Definitely isolate the one that you found the adults on. Continue to be vigilant in removing/killing them (neem oil, the best stuff ever, alcohol etc....whatever you prefer).

If you find them on a good number of your orchids, then I would suggest using a stronger insecticide (such as a systemic).

So far I've only found three mealies on a total of two plants, so it's not a hostile takeover. I'm hoping I caught them early and that'll be the end of it. I know they only showed up today because I watered this morning and found them this afternoon.

These buggers hide well check daily maybe a few times a day check in the nooks and cranys of the leaves where stems join them and yes chec all clips on the spikes they hide in those too.
Good luck!

Ummm... I was fighting these guys this winter. I have about 70 orchids, and here is my view - FWIW...

Yes - QUARANTINE that orchid and the surrounding one(s). Don't be overly aggressive with the insecticide (I used neem), and spray, watch, repeat. The plant will tell you if it's in distress by the color and leaves by either the mites or the insecticide. Just watch them..

As well, where the mites like to hide out (in my case?), was on the underside of the leaves, new growth and tender shoots/stalks.

Best to you,

John

How long should I leave the plant quarantined?

That's a really good question..

I'm never really sure when to reintroduce a plant out of quarantine. I still have my new orchids that I bought in march in a separate area than my other orchids.

I hope someone answers hehe!

I usually quarantine for about two weeks after I've finished the neem treatment (and I'm sure I have gotten all those tiny little critters ). I've been told one week is sufficient, but I just go a little longer.. I'd be interested to hear what others say as well..?

Hope this helps!

John

While I've had mealies here and there,I have found using a q-tip with alcohol works well for me. I watch the plant carefully after getting the mealies and repeat after af ew days. thankfully I've never had a major infestation. And for me they seem to appear on phals more than other orchids I have.

Thanks guys! I've only found three bugs so I'm not worried. I haven't seen any since I killed those three on Monday. So, I'm thinking that I'll leave them another week, and if I don't see any more bugs I'll move them back to my orchid shelf.

I found a Mealy bug today too. Then spent the next half hour looking over all the other orchids for more. Luckily I found only the one, and it was a new one I bought yesterday
