    Default New mealies after winter?

    I totally apoligize for this photo....I can't get good closeups. But I could not believe when watering this mini cymbidium that I was pretty sure I saw mealies. This thing has been inside the house since October and has not shown any. Can they be dormant so long? Needless to say, I separated and sprayed with insect soap.

    P.S. The mealies are around the new growth on the left.

    Hi , I can't see them on the picture , to answer your question yes eggs can sit dormant for quite awhile temp. and humidity trigger them . I would remove all the bulb coverings , unpot it, clean roots , submerge in a insecticide like Orthene wettable powder with a few drops of dish soap there are other insect products that is just what I use . The crawler stage of scale looks a lot like mealies . I had a battle with mealies several years ago that is the only way I got rid of them on my Cymbids . This is the time of the year in my area for false spider mites , low humidity , warm . Just thought I would mention it . My daughter had a battle with them on her Phals. Hope you can get rid of the little Gin

    I agree with Gin although I like Malathion as my nuke. I don't think these things are anything to mess around with. I know some people swear by less toxic killers like alcohol, but that has never worked for me. I think it's best to just use something you know is going to work and get it over with.

    I had a bad case of these a few years back during the winter. They really seem to love the flowers and suck them to wilting very quickly.

    Ditto to both those replies! Warmer temps and humidity can trigger dormant eggs to hatch out, so if this one was outside last summer, that's what happened.

    As Gin said, remove all the brown sheathing on the PBs--as much as you can. They love hiding under those, and the sheaths can protect them from insecticide.

    I just remembered I had this. A month or so ago, I sat down and figured out the ratios for mixing small amounts of pesticides. Sometime you only need a tiny bit to spray one or two plants and I really hate mixing up these things and dumping them down the drain (environment - bad for). You might find this useful.

    Oh yes, I actually found and verified a website that listed the number of drops in a teaspoon (60).

    Here’s my breakdown based on the ratio of 2 teaspoons pesticide per gallon of water.

    2 teaspoons pesticide per gallon of water (128 oz)
    ½ teaspoon pesticide per quart of water (32 oz.)
    ¼ teaspoon or 15 drops pesticide per pint of water (16 oz or 2 cups)
    7 ½ drops pesticide per 8 oz of water (1 cup)
    3 ¾ drops pesticide per 4 oz. of water (1/2 cup)

    Thanks for that info....this is very slow moving if it is mealies. It was unmistakenly cotton-y looking at first so I don't think it is scale but I don't have that much experience. What causes scale?

    Scale is a bug. Nasty, hard to get rid of, tiny little bug that coats itself with protective armour and it's the armour you see after it's built up. Scale does not really look fuzzy though. So if you have fuzzy-looking critter, it probably isn't scale.
