    Mealybugs! HELP!

    I'm freaking out...

    Last week I found the cottony "growth" on my S. rubra and isolated the plant. Now I'm finding the little ***** on my N. ventricosa (pitchers only it seems), D. 'pretty rosette' (flower stalk) and the VFT (in and out of the traps). They've also since been isolated.

    I'm super confused as to what is the best angle of attack to take. I was originally told 70% rubbing alcohol, but I've also read adding in dish detergent. From a search on TF here I've seen various pesticides recommended however I've NEVER had to use any so I'm a bit hesitant. Also, in my area it will be probably be impossible to find anything unless Walmart would carry it out of season.

    I've also seen it suggested that submerging the crown completely may take care of the ones hiding within the roots and soil. I uprooted everything and I cannot find any in the media, granted that doesn't mean they aren't there. I'm worried that re-potting will just transfer them over.

    Again, I'm super worried that if I don't stop this soon my entire collection will be infected. So far the plants are still growing well, which I've read isn't out of the ordinary for minor infections. But I don't want it to get any worse.

    I don't think submerging Sarracenia is all the effective. There are just too many areas that trap sufficient air to keep some mealybugs alive unless you submerge the plant for an extended amount of time (4 or more weeks).

    I had a bad root infestation which I hope is under control. I used a systemic insecticide from Bayer Advanced Complete Insect Killer for Soil and Turf. It's the same formula as their Rose and Flower Insect Killer but sold as a concentrate. The instructions said for soil pests to use a concentration 6x that of the spray. I used that to drench the media and roots in combination with spraying (normal concentration). So far I've not found re-infestation. Spraying alone was not effective as the mealybugs in the soil would survive.

    A combination of systemic spray and the alcohol/detergent swab appears (knock on wood) to have control an infestation of Pink Hibiscus Mealybugs, a particularly nasty species of mealybugs (google 'em).

    Even if you isolated the plants I would treat all your plants (where safe depending on Genus). The crawlers get around and you can actually inadvertently transfer insects from plant to plant on your hands or clothing.

    I would say the ICPS website gives sound advice:

    So this is what you used?

    Unfortunately it seems like I have to order online, which is going to take time if I can even find it...Would it be worth starting the alcohol/detergent swabs? What combination of that would I use?

    Also, how long should I treat? The swabbing seems to be recommended at once a week.

    Start with alcohol spot treatments. I have mealybugs in my gecko terrarium, and the spot treatment wasn't enough to get rid of them, even with consistent treatment. That's getting completely torn down, sterilized, and redone.

    Personally, I'd cut off all of the affected leaves, possibly even all existing leaves. These little guys are serious, and sometimes drastic measures must be taken.

    Phew, ok that seems to be an easier product to find even though I may have to order online. How often did you spray/soak?

    Will do.

    Is the detergent worth adding to the alcohol?

    I agree. As you just discovered, they have infected more plants than you realize. While treating plants is a pain, it's worse to have to keep treating them because you continue to find outbreaks in the plants you didn't nuke.

    I drenched once a month for 3 months. I poured the solution on the crown until it began to run out the drain holes of the pot. Individual trays (basket liners). Plants were not watered with straight water until the trays had dried up. Spray at the recommended of every 7(? memory!) days for 6 weeks.

    The detergent helps dissolve the waxy coat of the mealybugs to better drown them with the alcohol.

    One common home recipe I was given by another Sarracenia grower is 1 part 70% alcohol, 1 part 409 cleaner (light detergent), 4 parts water. You can use a spray bottle as long as you don't overdo it. The 409 is rather mild to begin with and further diluted. I would eventually flush your pots out with water though.
