Just been to look at my indoor plant and found blotches on the leaves. On closer inspection i found these.
Can anyone help to identify them?

Thanks for your help

it looks kind of like spittlebugs

I think I’m wrong about spittelbugs I’m watching to see the answer on this one

No clue @markky what part of the world are you in so I know who to tag? Country is fine.

white fly pupa?

“The nymph is a flat, elliptical, scale-like object, closely fastened to the underside of a leaf. It becomes fixed after the first molt. The nymphs, after the first instar, are flattened, oval, and are similar in appearance to the early instars of the unarmored scale insects.”

In Russian, but translatable. I think you were right: scale.

With that " HERE YA GO " I added the Sooty Mold and Ants

Scale (Outdoor Problem)

Scale can be found on stems, underside of branches, trunks, young trees or shrubs. They usally emerge from there eggs around March to Aug and make there homes on the plant. They pierce the cells and feed on the sap of the plant. After they have a place on your plant they devlop a very hard shell which protects them from other preadatory insects and chemical compounds to get rid of them. After they develop this hard back the secreation they drip attracts ants. Now since the ants travel over the scales thus dragging it all over your plant spreading the scale from one place to another on the plants. When the secreation falls on leaves it can make a type of mold called Sooty Mold which makes the leaves look dirty and black.

Sooty MOLD

The problem with this type of fungi is that it attracts several types of sucking insects,like Aphids, Mealy Bugs, Thrips, and Whiteflies…This mold is so dark that it affects the plant by inhibiting the light from reaching its leaves which stops photosynthesis, which in turn makes the plant die.


The waxy layer that is on scales protects them from insects and other pesticides. In order to get rid of them Use a horticultural oil to kill the adult populations throughout the year. If you can combine the oil with the insecticide, such as, Orthene, Sevin, or malathion it can almost wipe out the scale population along with the sooty mold it causes!Neem soil works very well too!

You can do a few things… more if your not nearing the end of harvest…

  1. take a pack of chewing tobacco, mix it with a gallon of water, let it brew for a day… spray the plants down as needed… if your a cigarette smoker no worries spray em down till harvest… watch for mold…

  2. take some safers natural soap, mix it with some water so its a soapy slippery mixture, soak em down… the idea is to suffocate the bugs in the soapy bubbles…


Ants are all over the place indoors and outdoors. Ants can be a pest in your garden, because there homes are underground in the colonies which require them to burrow through and thus causing root hairs and roots to be damaged from there digging.
Though generally they do not cause damage to the leaves from biting they may be eating dead leaf tissue, there may also be a hidden side to ants. Ants can carry aphids to your plants and thus causing the infestation, they can also be attracted to your plants if you already have a pest infestation. Aphids, mealy bugs, white flies can secret a sticky substance known as “honey dew” which is a sugar concentrate from the plant’s sap after aphids have excreted it on the plant. Ants love this and which is why they are attracted to plants that have an infestation. This honey dew that is secreted from pests can attract sooty mold where ever the honey dew is secreted on the plant.( See Sooty Mold for Details) If your plants do not have an infestation of pests, but you see ants you need to get rid of them, because of them being able to carry pests to your plants.
Ants are generally attracted to plants that already have aphids; white flies mealy bugs and scales. You can see ants on the plant and around the soil and in the soil. Your plants may show a different number of problems, but the main damage is not caused by the ants, it’s the pests that the ants may bring in or what they are attracted to on your plants.

Prevent and Control

To make sure you can keep ants away from your plants, you need to make sure your plants are free of insects and other pests that ants are attracted to. There are many ways you can deterrent ants from wandering into your grow area.
Boric acid is an inorganic powder that must be kept away from children and pets. Sprinkling it around your soil will help kill them when you water your plants, while the boric acid gets into the soil. Boric acid will not be toxic to your plants; it is also used for a cure when your plants have a boron deficiency. Do not apply boric acid on the plant itself; this is for soil plants, and areas around your plants that are outdoors.
Sticky traps or tangle foot can help for the upper parts of the plants that have ant infestation. Cucumber parings can also be used as a repellant. Lemon Juice mixed with 50/50 water can be sprayed on the plant as a repellant. Using common herbs like sage, mint leaves, and spearmint. Mixing some of these with water can be used to spray onto the plant. Using peanut butter ball with a bit of sugar on it can be a sticky trap where they can’t get out of. You can put it near the soil or small bits on the leaves, or where high infestation areas on your plants. Watering your plants with apple cider vinegar can make them come up and can also kill the larva in the soil. Flushing well before using methods can help out a lot due to flooding the nest makes them come up out of the nest and killing there larva from drowning. When they come up using a deterrent can chase them away, if not use any one of these items to kill them or deterrent them. Chemical Control should always be the last resort for cannabis plants. Other ways to combat ants with chemical ways:

Chemical Control

Malathion Plus
Insect spray concentration
Ant Baits
Ant be gone baits

Organic Control

Instant Grits (causes dehydration)
Cayenne pepper
Citric extracts
Cream of tartar
Cucumber parings
Peppermint tea
Schultz-Instant Insect Spray

(Deterrent and Kill)
Water with apple cider vinegar
Flooding the nest with lots of water
Boric Acid
Orange peels, chopped, or grinded and lay on the soil top.
Orange Guard
Boric Acid mixed with sugar and water added a bit of peanut butter and laid in the soil.
Safer Sticky Stakes

Hi Everyone,
Thanks for your posts and information esp. garrigan62.

Just for info this is indoors.

You got to be careful when you come in from outside. If you have been out in the woods or close to it you should change your clothes before entering your grow room
