How to recognize aphids?
Aphids have also become emerald flies and whiteflies, and are common pests of mulberry leaves. Depending on where they live, they will appear white, green, yellow, black, brown, and red, and they are widely distributed throughout the world. No matter where hemp is grown, they can become the main pests.
These small whitish bugs are the larvae of aphids, and the larger ones are adult aphids.

Aphids are also black. This is a cannabis plant covered with aphids.

The adults of some aphids will grow wings and fly, looking like tiny black flies or green flies. Regardless of whether they have wings or not, the appearance of adults of aphids is very similar.

Aphids that attack cannabis are often green and sometimes difficult to spot.

What is the harm of aphids to hemp?
Aphids are common cannabis pests, and their life stages are divided into larvae, nymphs, and adults. The larvae are small and generally whitish; the nymphs become longer, oval, and pale in color; the adults will become larger and rounder and look more plump and juicy. The adults of different aphids have different colors but similar shapes.


Aphids use their mouths to pierce the cannabis leaf and feed on tissue fluid. They usually gather on the lower part of the stem and the back of the leaf. If the cannabis is severely damaged, the leaves will yellow and wither, the branches will shrink and deform, and eventually die completely.
Aphids also have a major hazard. When aphids feed on plants, they also produce sugary liquids that attract a fungus called soot mold. This kind of mold will multiply in the secretions of aphids. Covering branches and leaves indicates that it hinders the respiration and photosynthesis of the leaves and exacerbates the death of the plants.
What causes aphids infestation?
When aphids crawl or fly on the hemp, they will lay a large number of eggs, using the new hemp as its breeding base. Winged winged aphids are the most aggressive.
Once hemp is exposed to the outdoor environment, it will face the risk of aphids erosion. This hemp seems to be full of THC and is about to mature, but there are many aphids hidden among these alluring hemp oils. Look carefully, can you see it?
Aphids larvae shed their exoskeleton after 7 to 10 days.
If aphids need new plants, they will grow wings and look around. If they feel that the current plants are nutritious enough, they will not grow wings and focus on multiplying.
Because of their rapid reproduction, healthy plants can be completely dead within a few weeks.
After eating up the plants, they will grow wings to find new victims.
Solution to treat cannabis killer aphids
Prevention is the best way. Try not to let your cannabis contact the external environment. Once infected, you can only use insecticides. Be careful not to use highly toxic pesticides that can destroy the nervous system. Be sure to use low-toxic pesticides that can be used on crops.
- Regular inspection
Every half a week, carefully check whether there are obvious white spots on the roots and the back of the leaves of the cannabis, and take decisive measures if there are any. - Disinfection
Move the plants outside and spray the plants with insecticide to remove the heavily infected buds and leaves. Products that are more effective against aphids are:
Insecticidal soap
Cut off a small piece of soap and dissolve it into the watering can, shake it more after it has melted, to produce a lot of foam, and then spray the cannabis. There are special insecticide soaps on the market.
Neem Oil
The oil extracted from Neem, the Ayurvedic herb, kills insects very effectively and is fast and lethal. But this insecticide has a strong smell and is slightly toxic. Spraying around the buds will destroy the taste.

Spinosad
This product is organic and completely harmless to humans and animals. Its effect is not as good as those powerful insecticides, but it can be sprayed on the plants in large quantities, killing aphids while washing them.

Essentria IC3
It is an insecticide mixed with organic ingredients and is called “Bed Bug Killer”. It is completely safe for animals and storage, and can be used frequently and short-term. But its effective time is short, only 8 hours. If you use it to remove insects, you must insist on using it until all the pests disappear.

After killing the pests on the plants, the indoor environment must be thoroughly disinfected to prevent the pests from resurgence.
- Introduce beneficial insects
If your planting scale is large, and often affected by aphids. A large number of beneficial insects can be introduced from breeding companies to fight against pests, such as ladybirds and lacewings. It should be noted that the ants will protect the aphids to obtain the sweet secretion of the aphids. If there are ants near the hemp, these ants will keep the aphids in a large number. Do not leave ant nests near the hemp.
It is not difficult to deal with aphids, it is rare to find them before they become infested. Growers who are often exposed to cannabis plants need to check the plants regularly to find these annoying pests and deal with them in time.
