    Bugs and Pests on Cannabis



    Bugs and Pests
    Put simply, pests and bugs are the nemesis of growers. Here on HTG we have addressed the issue in the past. It is practically impossible not to encounter them in your grow environment. For bugs, your marijuana growing setup is like the Garden of Eden: a friendly environment, abundant with food and relatively safe from predators. That is of course until you go all Sherlock Holmes on them with your 8X magnifying glass (that’s the minimum magnifying power you’ll need to spot them critters). It’s best to check for pests under your plant’s leaves. Alternatively, you might need to try to spot slight stains on the top of the leaves in order to realize they’re even there. Most of them are incredibly tiny, so there is a good chance you’ll miss them if you’re not too careful. If you’re thinking chemical pesticides, you’d better forget it. Contrary to other plants, cannabis does not like chemicals (not to mention your end product will be poisoned, ergo un-smokeable). Luckily, there are many organic alternatives, like neem oil, pyretine or pine soap solution. You can also make your own all-purpose natural pesticide from red pepper, chili powder or soap and water. Below, we will list all the major threats to your plants and their feeding habits, as well as ways to get rid of them.
    • Tetranychus urticae (Spider Mites, Broad Mites);
    • Fungus Gnats;
    • Whiteflies;
    • Thrips;
    For flying pests, carefully placed traps around your grow room might be a pretty good prevention measure, however, nothing can replace regular inspection with a magnifying glass. Let’s take a (much) closer look at the insects one by one.
    Mites
    [​IMG][​IMG]Mites are orange-toned arachnoids, and they are almost inconspicuous: less than 0.5 mm long. They are one of the worst infestations that can happen and usually they occur from inadequately sterilized soil (see: cheap soil) or if you move outdoor plants indoors. Usually, these pests occur when the humidity is below 80%. If you notice fine spider webs with larvae among the leaves of your plants, then you are certainly dealing with spider mites (and the infestation is already at a very advanced stage). If your cannabis plant’s leaves are taking a rough yellow undertone and are starting to fall off, it is probably infested with spider mites.[​IMG]Mites love dry and warm environments, so to exterminate them, it is often sufficient to spray your plants regularly and maintain a healthy level of ambient humidity. If you have already noticed that some of your plants are infected by mites, remove them from your grow room immediately, to avoid spreading the infection and apply an organic pesticide (see above for more information), paying extra attention to the underside of the leaves. Raising humidity and lowering the temperature also helps a lot with mites and will often be sufficient in reducing their population. However, you should bear in mind that mites are extremely resilient and it will take a lot of work to take them out. Check regularly, even long after you think the problem disappears. Also, never let pets around your plants: they can infect them with mites.
    Fungus Gnats
    [​IMG]Fungus gnats are a common nuisance for soil cannabis growers. They appear on over-watered plants, thriving in the humid and decaying conditions that careless growers have created for them. Higher temperatures and a wet top soil, guarantees that you will deal with fungus gnats sooner or later. Fungus gnats love to lay their eggs on the wet soil. These eggs later develop into larvae, that like to gnaw on whatever they come across. Their insatiable hunger can deal a lot of damage to your plants’ roots. Fungus gnats are especially threatening to younger plants and should be addressed as soon as you realize that they have infected your plants’ soil. Unlike other pests, fungus gnats are easy to spot. While adult gnats are not so much of a threat, they do spread diseases to your plants and they are almost certain to have laid their offspring in your wet cannabis plants’ topsoil. Obviously, the best way to avoid fungus gnats, is to avoid over-watering your plants. That is enough to prevent them from ever bothering your plants. If you have already been infected, there are some ways you can get rid of them.[​IMG]
    • Fill your grow area with yellow sticky surfaces. Fungus gnats love yellow. So these traps will help you measure your effectiveness (you will be able to see all trapped gnats).
    [​IMG]
    • Don’t water your plants for a while. Before you start applying insecticide over your soil, you’ll want to exterminate all larvae. There is no better way of doing this, than drying out your topsoil.
    • Blow air directly over your marijuana plants. Just use a fan or any other device with air-blowing properties. Gnats will find it difficult to fly around your plants and the air will dry out your soil.
    Whiteflies
    [​IMG]Whiteflies live on the undersides of cannabis leaves and love to chomp on the plant leaves. Although they are significantly smaller than regular fruit flies (also they are, quite obviously, white), they still very capable of spreading dangerous diseases to your plant. This airborne threat can ruin your harvest if left untreated. Whiteflies can be prevented by sticky traps all over your grow room. If you notice that they have started infesting your leaves, spraying them with neem oil will usually do the trick. Also, soap and water is considered to be an effective home remedy, like thinned garlic and onion juice as a foliar spray. Diluted SM90, a commercial wetting agent, is a good way to control whiteflies
    Thrips
    [​IMG]Although barely visible, thrips can mean a lot of trouble for your plants. They reproduce in a menacingly fast rate and that makes them very difficult to deal with. They have little piercing mouths that suck the sap right out of the leaves of your plant, turning them white. So, if you notice that your leaves looked like they had all the life sucked right out of them, this is because exactly that happened. Also, their condition is not reversible, meaning that if the infestation is left untreated, thrips will kill your plants. Another way to spot thrips is by the excrement they produce on the leaves, which is black, with a tint of green. Finally, thrips can transfer viruses to your plants. A surefire way to repel thrips (for outdoor grows) is to use garlic. Also, it has been found that the color yellow attracts the thrips and should be advised not to have this color around your grow. If you have already been infected, spray them with neem oil or use lady bugs against them. In severe cases of infestation, you need to use biological warfare, like pyrethrin-based insecticides.
    Aphids
    [​IMG]Much like thrips, aphids are extremely tiny, meaning that spotting them might be a challenge in itself. Generally, they like hiding underneath the leaves and suck the nutrients off leaves. This causes a very noticeable discoloration to the leaves, which turn yellow and wither. Aphids can also carry viruses and diseases transmittable to plants. They seem to thrive in environments around 60-80ºF (15-25ºC). Like all of the pests feeding on plants, they produce excrement (honeydew), that can act as a magnet to other bugs and ants, creating an additional headache to growers. Although ladybugs tend to naturally solve the problem, there are several home remedies you can implement to reduce aphid infestation:

  7. Hit that girl with DE and call it a day...

    DE = Dietanicous earth

    Spelling is off I know and I am too lazy to look it up let alone auto correct nailing it.

    Just don't dust her while in flower. Dust one more time at the transition and let her eat.
