How to remove thrips of marijuana plant
One of the greatest difficulties to end these insects is that many of them nest in the own potted plant if you do not notice it, this type of pest will regenerate every so often in our marijuana plant, to finish permanently with its health. Fortunately, there are different methods to end it.
Today we return to one of the most common insect invasions in marijuana plants: the thrips. This is not one of the worst pests that you may have, neither is particularly difficult to remove, but the truth is that pests are persistent and which, if not check very well the whole plant continuously, can move from side the presence of any of these insects which, unfortunately, are reproduced with relative ease.
How to recognize the thrips
They are small insects, from 0.8 to 3 mm and it should be noted that females are usually larger than males in this class of insects. It is further composed of wings, allowing them to move relatively easily throughout the plant and lay eggs, therefore, throughout the plant. In fact, this is one of the drawbacks of having an infestation of thrips: unlike other insects that are usually placed below the most weakened leaves, this type of insect can be throughout the plant, even in the soil of the container, where often the females hide the eggs and hence we can not see and have several reproductions of pest thrips in our plant throughout the year.
Another aspect to be taken into account are the favorable conditions that allow the reproduction of these insects and that is the temperature (between 20 and 25 degrees) and a dry environment. Something that usually occurs in indoor crops and therefore are more likely to appear in them, not in outdoor crops marijuana.
When thrips attack the marijuana plant, what they get is weakening and curb also growing. Also, you will recognize because leave small holes in the plants, which will be the places where they have food and also because’ll see small white or yellowish spots, which are the eggs they lay females. Once thrips invade your plant, this will also lose color, something you will notice on the leaves of your plant, which will begin to have a faint green color, pulling to yellowish.
How to combat the pest thrips
Of course, and as we always say, the best, before having to meet face this situation, is to try to prevent it. This requires the following steps:
Place anti insect screens on vents, that will allow this type of invaders did not come into your plant. In this regard, it is important to check the screen every so often to check that it has not evolved and have not made any hole insects that want to invade our plant.
To use neem oil. Spray your plant with this biological preventive help your plants in its development. They will be stronger and less likely to suffer from possible invasions of insects.
Place yellow sticky bands: they attract insects, stay stuck in them and can not reproduce or re-plant.
But if you could not avoid it and you are before an infestation of thrips, the steps to end it are as follows:
Maintain humidity below 40%: so that they can not reproduce.
Natural predators: ending with those insects, but that do not damage the plants, such as ladybirds.
Insecticides: specific for this type of pests.
Above 35 degrees: from that temperature, thrips are not generated, so depending on the time of flowering on your plant are, you can make your closet comes to have that temperature and thus avoid the reproduction. This method can be dangerous, so we recommend you use caution.

Thrips – How To Get Rid of Them?
Thrips are a common threat to cannabis cultivators. They are small pests that look like little worms or flying insects. They are tough to get rid of and survive by sucking the sap out of your plants. Here is a quick guide to spotting thrips, and a few ideas for preventing and controlling an infestation.
Growing cannabis can be an exciting and rewarding hobbie. But what happens if others decide to enjoy your cherished crop before you do?
WHAT ARE THRIPS?
Thrips are a common problem faced by canna-cultivators. They are a minute pest that literally suck the plant sap out of your crop. Thrips also come in several different species. They can be tiny winged insects (measuring in the millimetres), or they can look like small, pale worms.
Regardless of their species, thrips are the bane of farmers everywhere. They can reproduce up to 12 times per year. When mature, they can survive just by flying from one plant to another. Outside of cannabis, thrips’ favourite crop seems to be cotton, although they can damage many kinds of crops. But they really seem to love cannabis! Unfortunately, they are particularly damaging when they appear early on in the grow process.
The most damaging thrip threat to cannabis comes from a species called Frankliniella occidentalis. These thrips are yellowish-white flying bugs. They lay their eggs on the plant itself. The first signs of their presence are small, silver stains or dots on the underside of leaves. This is how thrips lay their eggs. They are also easy to miss.
Worse? While not a significant threat to outdoor growers, they thrive inside. Indoor grows and greenhouses are their favourite environments. They love high temperatures. Thrips can also be persistent if not treated properly. And if not eliminated early, they can significantly reduce yields.
THRIP PREVENTION AND CONTROL
The best way to rid yourself of thrips is to never have an infestation in the first place. Make sure that you thoroughly sanitise your growing space before you begin. This means not only keeping the place spotless, but removing all dead plant matter.
Once the grow space is set up, install insect adhesive strips. Much like fly paper, these are insect traps that will catch most of the free-flying bugs around. The bugs will get glued to the strips. Problem solved.
Eradicating thrips once they have established a presence is the only way to save your crops and prevent a new infestation. The best method (without using harsh chemicals) is to use potassium soap or neem oil. Pyrethrins and rotenone are also good options, although use sparingly as pyrethrins are also highly toxic to bees.
Thrips are a common pest facing indoor cannabis cultivators. They can seriously damage the plant and lower yields. Here is a guide on how to get rid of them.
