Very small white larva, Hedera helix

smishgibson(7b)November 27, 2013

Found these on some variegated hedera helix cuttings i have under lights.

I held a 200x loupe over the leaf and took a picture through it with my cell phone.

To the naked eye, they are larger than adult spider mites, but still very small.

For now, i removed all i could find manually with a paper towel wet with 50/50 water/isopropyl alcohol.

An aphid. Squish them all.
Then check daily in case you missed any of their kin. ('Cuz you probably did!)

Aphids. These are quite simply controlled with sharp water sprays that knock the wee buggers off the plants.
Alcohol is not a good insecticide and can do far more damage to plants then the insects the alcohol is meant to control. Alcohol can interfere with photosynthesis as well as cause a plants leaf to loose cell moisture, just as it draws moisture from your bodies cells.

Kimmsr, rubbing alcohol is very commonly recommended as a safe and efficient control for mites, aphids, mealybugs, and other small pests. I've used it for years on a wide variety of indoor plants with zero problems.

It is often applied as a diluted spray mixed at the rate of one part alcohol to three parts water. Hedera helix would certainly be one of the safe plants.

Thanks so much for the ID guys. I feel silly not knowing something so common as an aphid. I guess I'm just lucky I haven't had to deal with them yet. Two treatments of manual removal with water/alcohol seems to have done it. I will watch this and all plants in the same room closely for a week or so before I call it done.

Rubbing alcohol is my go-to treatment for any plant with smooth (not fuzzy) leaves. You can also use it on a cotton ball or q-tip, to gently wipe leaves, whatever's appropriate for the plant/leaf shape and your patience level.

For a similar look without so much potential for pest population, consider variegated Hoya carnosa, Philodendron 'Brasil,' Ceropegia, Syngonium, Columnea, Aptenia cordifolia. These all have very pretty (IMHO) leaves, a dangling habit, without the reputation for being virtually impossible to keep pest-free (like ivy) though any plant can get some kind of pest.

i am with kimmr on the water ... its basically free ..

if small enough.. start shower .... invert in one hand .. and give it a shower ... presuming i suppose.. you have a hand held shower head ...

just wash it off for a few weeks running.. interrupt the breeding cycle ... trying to avoid making the media sodden ....

all my house plants are outdoors for summer... in mid fall.. i treat with a systemic .. outdoors... to insure that what i bring in.. has sterile media [in terms of bugs] ... as well as clean plants ... prevention is so much easier than the cure ...

I'd love to see a pic of one house plant of yours, Ken.
