Natural and System Solutions to get rid of Spider Mites


Spider Mites are one of the most problematic bugs that can effect a cannabis garden. There are many solutions on the market and each has its own benefits and down sides. We will outline some of the most common and effective solutions that are commonly used today.

Step 1 – Confirm the infestation affecting your garden is spider mites.

First you want to identify your problem and be sure it is Spider Mites that is plaguing your plant. The first signs of infestation involve small yellow dots on the upper side of the leaves. These dots are caused when the Spider Mites, who prominently live on the underside of the leaves, damages your plant.

The bugs themselves are very small and and on the underside of the leaves are very difficult to see, but if you look carefully you can see the small little bugs as well as thin webs that typically run along the outside of the leaves and along the leaf “spine”.

An infestation of Spider Mites must be dealt with quickly because they can spread quickly and easily ruin a crop. There are many methods to rid yourself of these little pests, but they are common and the most effective form practices are those done BEFORE an outbreak. Preventive measures are key.

Step 2 – Eliminate or attack the existing spider mite infestation.

How to get rid of Spider Mites With Insecticide

  1. Forbid – This is a tried and true method of controlling spider mites. Forbid is a type of ornamental insecticide which is used by gardeners in order to control the population of insects specifically spider mites. Forbid protects the plants against the damages caused by these plant-eating bugs. It contains a kind of powerful substance which prevents the bugs from hatching their eggs and thus reducing their population. Forbid is perfectly apt for using it as a long-lasting solution against various types of mites, however Forbid should not be used during flowering. The fact that this chemically is systemic means that the plant will have trace amounts of Forbid for several weeks. This is great during vegetative growth as it will keep spider mites away, it may not be healthy for the end user when present in flowers that will be consumed.
    How to use Forbid to get rid of Spider Mites?  Forbid contains a highly active ingredient known as spiromesifen which targets the stages of mite development. Though it is more effective on juvenile bugs, it can also cure adult bug infestation. The use of Forbid can kill or restrict the growth of any kind of bugs by 80-100 percent. All you need is a spray of Forbid, and allow time for the chemicals to take effect. Many of the mites will die within the first few days after exposure however some of them, specifically adult males, may live for several more days. In my experience over the next week or so all of the remaining pests will die, the plants will be systemically resistant to spider mites for the next several weeks.
    Where do get Forbid?
    We have gotten some great results from growers using Forbid. Highly recommended but it is necessary for growers to use the proper personal protective gear when working with or around Forbid.
  2. Avid – Avid is miticide used to eliminate the problem of insects from your garden. Avid can be an expensive solution which is typically used as a last resort in order to salvage a garden. Avid contains an ingredient known as abamectin which acts as a nerve poison for the insects which directly affects the nervous system of the insects and thus, killing them. Avid shouldn’t be used regularly as it lasts long in your plant’s system and can be quite harmful to the grower if not used properly.
    How to use Avid to get rid of Spider Mites?  Mix Avid with water per the instructions on the label. For most applications a 4oz container of Avid should make approximately 100 gallons of spider mite treatment. While the bottle may be expensive the amount of miticide that is made will last most growers several years. It is important, as with Forbid, that growers who apply Avid to their garden wear the proper personal protective gear and provide themselves with the protections that are outlined on the Avid bottle label. Avid, like Forbid, can only be used during the vegetative period and should not be used during the flowering period. Avid is not safe for consumption so please use with care and caution.Where to buy Avid? There are many resources for Avid but we have found some of the most reliable to be Amazon.

This secondary treatment should be with an organic solution, and not the same organic solution that has been used in Step 2. Spider Mites are known for their ability to develop a tolerance to many different treatment methods. By accompanying multiple methods of treatment you can be sure that you have killed off all of the bugs.
    In addition to the organic solutions such as Neem Oil and Spinosad that were mentioned in Step 2, there are several other solutions that can be used in Step 3, some of these solutions include:

    1. Insecticidal Soaps – Insecticidal soaps are a great and inexpensive way of attacking a spider mite infestation. while i would not use this as a singular method of eradication, insecticidal soaps can go a long way in reducing an infestations population and coupled with a more powerful insecticide will assist in eliminating those last stragglers as well as making the plant less of an attractive area for new bugs.
    How to use Insecticidal Soaps to get rid of Spider Mites? 

    • Try and avoid applying insecticidal soap to sensitive areas of the plant, or to recently rooted cuttings.
    • Shake the solution of insecticidal soap well before applying it.
    • If you are using insecticidal soap for the first time then, it is advisable that you first carry out the 24 hours test. Apply the solution to an inconspicuous branch and wait for 24 hours to make sure whether your plant can tolerate it or not. If you find burned spots on the plant then, discontinue using it or at the very least dilute the solution and test again.
    • Before, applying the solution make sure that your plants are watered well.
    • The best time to apply insecticidal soap is early in the morning or in the evening when the temperature is relatively cool.
    • Look for the infestation area and spray the solution thoroughly because it will only work on the insects that are actually exposed to the solution.

    Where do get Insecticidal Soap? Insecticidal soap is one of the few items that can be made at home or purchased online. If you are planning on making it yourself use a pure soap, ideally liquid. The ingredients in insecticidal soap that harm spider mites are the fatty acids that are used to make all natural soap, so it is essential that the soap you are using is the real thing. Once you have acquired the proper soap, mix 4 tablespoons of soap to 1 gallon of water and shake well. The solution that results should be spray tested on an inconspicuous branch and checked 24 hours later for burn marks.

    2. Diatomaceous Earth -There are plenty of pest control methods available in the market that is used by gardeners to protect their precious plants from the hands of the plant-eating bugs. Depending on the type of bug that infests the garden gardeners choose their pest control method. Among the various methods available, Diatomaceous Earth is also used by gardeners to control pests. It is quite a popular and natural way of eliminating these tiny destroyers from one’s garden. Diatomaceous Earth is a powdery substance which is quite famous for its ability to kill bugs naturally. Diatomaceous Earth is a naturally occurring substance that is extracted from an algae-like plant known as Diatoms. When Diatoms die, they leave behind a powdery substance which is used by the manufacturers to produce Diatomaceous Earth.There is mainly two types of Diatomaceous Earth: Food-grade and Filter Grade.

    Step 4 – Preemptive measures to insure that the infestation does not return.

    Once you have eliminated all traces of the spider mite infestation it is time to start preemptive measures that insure that you do not have this problem again. Many growers do not realize that there are spider mites all over the outside world and contamination can happen any time. Some of the preemptive methods are simple and straight forward but if not done can result in a resurgence of the pesky bugs.

    1. Use a Fan – A simple fan in the grow room can help in preventing many different problems. Constant air flow will make it more difficult for spider mites and other small bugs to get a strong colony going within a grow space. Many growers use specialty fans that are designed to be mounted on the wall of a grow room. These fans when paced properly can provide more than enough airflow to circulate the air throughout the room, assisting in the spread of insecticides or other natural spider mite deterrents. Wall mounted fans also assist in moving the air above, under, and around your plants allowing the to have a cooler temperature and generally stronger stalks.
    2. Keep a Clean Grow Area – One of the most straight forward ways to maintain your bug free grow area is just to keep the grow area as clean as possible. Many growers I know have come across spider mite infestations that were very difficult to get rid of, and in the end it turned out to be because a part of their room was unable to be properly treated for one reason or another. A common place for spider mites and other pests to hide within a grow room is in the soil or dirt trapped in small spaces within the grow area. The easiest way to combat this type of exposure is to first sweep the grow area as best as possible (when possible) and second to spread Diatomaceous Earth on the floor, potting soil, and any other surface.
    3. Check Your Clones – It is very common for a grower to want to grow a different strain or variety of plant and this frequently leads growers to purchasing clones. Many times new or un-trusted clones being introduced into a grow room can be a source of any number of pests including spider mites. It is very important when you purchase clones to thoroughly inspect them for any type of deformity or abnormality. A few moments spent checking to be sure your clones are clean and pest free can save you hours of work later.
    4. Schedule Weekly Maintenance – If you are serious about keeping a bug free grow area it is imperative that you schedule a weekly maintenance routine. For many growers this includes spraying one of the organic pesticides as a deterrent in order to keep the plants less inviting to any pests who may be inadvertently introduced to your grow area. The organic spray should be applied bi-weekly with a different chemical deterrent applied in the off set weeks. Personally I use a 3 week schedule. Week 1 is Forbid, week 2 is neem oil, week 3 is insecticidal soap. A broad selection of tools in which to fight the spider might invasion insures that you are always one step ahead and that the spider might population is not able to gain a foot hold into your grow area.
