Even if there are additional pests that may harm your succulents, the majority of infestations will be caused by one of these four bugs.
Mealybugs
The fluffy, white insects known as mealybugs are typically found in big numbers. Although you might mistake them for a spiderweb up close, they have a distinct, cottony texture.
They adore living in cracks and other secret, safe places. Check the areas of your succulents where the leaves meet the stem; this is a preferred location.
Fortunately, mealybug infestations are fairly simple to manage. You can just unpot the succulent and thoroughly rinse it out with a strong stream of water if the infestation isn’t too bad. That ought to be sufficient to remove all of the mealybugs.
You should repot the plant in new soil because some species lay their eggs in the soil. If you’re unsure whether your soil is contaminated, you can bake it at 200 degrees for a couple of hours to eliminate any hidden pathogens.
Apply rubbing alcohol to the affected areas of the plant if water is ineffective or you don’t want to repot the plant. The insects will be instantly killed by regular 70% isopropyl alcohol, but your succulent won’t be affected at all. Try spraying the plant liberally with alcohol after filling a spray bottle with it.
Scale
On the plant’s surface, scales take the form of rounded or oval bumps. They are very little, measuring no more than one centimeter or so, and are always dark in color.
It should be immediately clear why these insects are called scales since they are protected by a hard, smooth shell. When they reach the adult stage, they choose a location (typically along the stem) and stay there for the rest of their lives. They are fairly resistant to chemical treatments and almost impervious to predators.
However, they usually spread very slowly. If you notice a few of them on your plant, you may remove them quite quickly by scraping them off with a blade or your fingernail. If there are numerous, you should use a potent insecticide.
The solution is neem oil. Neem oil is frequently marketed as an extract and needs to be diluted before usage, so be sure to read the instructions carefully. Additionally, keep in mind that if the oil is on the plant and under strong, direct sunshine, it could result in sunburns because it is an oil.
Neem oil should therefore be used at night. That also lessens the chance of accidentally catching helpful bugs, most of which are active during the day.
Spider Mites
Spider mites are extremely hardy because they can overwinter in the soil and reproduce swiftly. They flourish in the same hot, dry environments that succulents do, unlike the majority of pests.
The tangled, wispy cobwebs that spider mites build around themselves to ward off predators make them very easy to recognize. They come in a variety of hues, including brown, black, and red, and many of them are so tiny you would need a magnifying glass to see them. Look for webs on the undersides of leaves, where they almost always congregate.
Although they pierce leaves to get the juices, the damage is done gradually. For a plant to actually be in danger, spider mites would need to completely cover it. To identify spider mites, look for random spots of yellow, brown, or gray scarring on leaves.
Washing away their protective web covering with vigorous water is the first step in getting rid of them. Apply neem oil next as you would for scaling. Treatment with isopropyl alcohol is also effective. An additional choice is to use insecticidal soap, which you can either purchase or manufacture by combining a few drops of dishwashing detergent with a quart of water. Use a spray bottle to liberally apply the solution.
Fungus Gnats
In reality, fungus gnats are merely a nuisance and not even a pest. However, they are very common and should be mentioned.
They resemble fruit flies in every way, more or less. perhaps a little smaller When you brush by them, they will occasionally take off in a swarm when they are resting on the leaves of your plants.
The adult gnats you see flying around have a relatively brief lifespan and barely consume any food. They lay their eggs in wet ground. The eggs develop into larvae that primarily consume decaying matter but may eat new, sensitive roots if given the chance.
Although fungus gnats are not very harmful to your succulents and cacti, they are a sign that your plant is overly damp. Give the plant extra time to dry out in between waterings or switch out the soil with one that is looser and faster draining.
It is quite simple to get rid of fungus gnats. The soil will eventually die if you thoroughly dry it up (without any water for around two weeks). The eggs and larvae will shrivel up, and the adults will eventually pass away. If you place a fan to blow over the plant, the adults won’t be able to return and deposit eggs because they are extremely slow flyers.
Water your plant with an alcohol or insecticidal soap solution and fully wet the soil for a quicker fix.
That is the quick-and-dirty method for removing bugs from your cactus and succulents. Do you have any questions concerning any other pests? Do you require more information? Tell us in the comments section below!
Common Mistakes with Succulents
The majority of the horror stories you’ll come across online stem from a few simple errors.
The following are a few of the more typical ones:
- NEVER spray commercially available, pre-mixed neem on succulents. Neem oil starts deteriorating as soon as it is combined with water, so by the time you receive the product, it has probably severely deteriorated. Furthermore, you have no control over the ingredients in sprays that weren’t made by you.
- NEVER mist plants in direct sunlight. The majority of succulent plants may get severe leaf burns if their leaves become moist while being exposed to the noon sun, because Neem oil degrades when exposed to UV radiation.
- Before submitting a complete application, ALWAYS test. One cannot emphasize this enough, especially with regard to succulents. Never spray the entire plant with your neem spray; instead, apply a little amount to a single leaf or piece of stem and wait 24 hours to see if there is a negative reaction. You should adopt an alternative approach if the plant exhibits any signs of distress because this indicates an allergy or oversensitivity to neem.
- On delicate plants, NEVER use raw neem oil as a foliar spray. Azadirachtin can result in serious burns and is much more harmful than beneficial. Instead, save the raw Neem for soil soaks and just use the clarified Neem for sprays.
- Neem should NEVER be used with other liquids, even isopropyl alcohol. Additionally to occasionally causing a reaction, many of the web advice are detrimental to your plants. The only ingredient for neem oil that is thought to be secure when used as an emulsifier is insecticidal soap.
Neem Foliar Spray
Clarified hydrophobic neem oil is used in neem foliar sprays, the most popular type of neem therapy.
Azadirachtin has been mostly eliminated from this variety of neem, with only.5 to 3 percent Azadirachtin left.
When dealing with delicate plants, always aim for 1 percent or less until the infestation doesn’t show indications of abating after two weeks of treatment.
Emulsify 1 teaspoon of liquid Dawn dish soap, insecticidal soap, or pure castile soap should be added to 1 quart of water before gently blending.
Avoid spraying the flowers or the exposed roots, but make sure to catch the undersides of the leaves as well as any joints or crevasses.
For a total of 14 days or until the infestation has disappeared, repeat the treatment every other day.
In order to protect beneficial insects and reduce your danger of becoming sunburned, it would be best if you only sprayed at dark or morning.
In 45 to 1 hour, the neem will vanish completely, leaving no trace left.
Special Fungicidal Recipe
This mixture will work on many succulents to control external fungal diseases, but you will need to test each item separately for potential sensitivities.
If the infection hasn’t progressed too far, remove any dead leaves and clip away any clearly affected leaves; if it has, you might need to leave those leaves alone.
Next, add two teaspoons each of clarified Neem oil and either olive or almond oil, as well as one teaspoon each of rosemary and peppermint oils.
Which plants should not be exposed to neem oil?
I started using neem oil in my garden a few years ago to get rid of spider mites and aphids, and I’ve grown to adore it. I’ve had great success using neem oil, which naturally repels insects, especially when it comes to keeping the pests away from my tomato plants.
But I recently discovered a hard lesson: Neem oil simply isn’t a favorite among all plants. Thus, the issue arises: Which plants should you avoid using neem oil on?
Herbs like basil, caraway, cilantro, dill, marjoram, oregano, parsley, or thyme shouldn’t be sprayed with neem oil. Neem oil should only be sprayed sparingly on plants with fragile or wispy leaves, such as spinach, arugula, lettuce, and peas, to avoid burning the foliage.
Be careful while mixing and applying neem oil, though, as even hardier plants with tougher foliage might be scorched (or even killed) if you don’t.
Neem oil is made to cover a plant’s leaves and any invasive insects lurking among them in an oily film that will suffocate some insects and harm many others by damaging their cells. Neem oil is an oil, though, so even on a moderate day, if you ignore good advise and spray at the wrong times, you risk literally cooking the leaves of your plants.
In light of this, let’s look at a list of plants that tolerate neem oil, those that are sensitive to neem oil, and those that don’t actually require neem oil because they already ward off many of the most pesky bugs.
How can I keep pests away from my cactus?
Mealybugs leave a white fuzz on cacti, making it simple to identify whether you have a bug problem. Mealybugs have the appearance of little crabs when they are fully developed. Act fast as these bugs multiply quickly. 600 eggs can be laid by a female!
Prevention: These little insects can be killed by hand by simply crushing them, just like killing a spider. You can wipe a mealybug with rubbing alcohol or spray it with a solution of liquid dish detergent and water if you prefer to use a more hands-off approach to bug control. After using the soap, allow it to sit for a day before giving the cactus that region a gentle rinse.
Neem oil for succulents: how to mix?
Neem oil can be used to succulents just like any other insecticide. Simply spray the remedy into the leaves, then check in a week or two.
The main distinction is that you cannot buy this insecticide already manufactured for you. Using this recipe, you must first dilute it with a little water and soap.
Neem Oil DIY Pest Recipe
- 1 tsp. neem oil
- 0.5 teaspoons liquid dish soap
- 1 gallon of water
- 1 bottle of spray
Make sure to thoroughly shake a large spray container after adding the components. To make sure you’ve covered all the spots on which those bothersome little insects prefer to feed, spray both the tops and undersides of the leaves.
Don’t spray directly on plant roots or flowerheads; just the leaves. The pests are killed when they consume the plant’s harmed components. This protects pollinators like bees and butterflies because they only eat from the flowers.
Neem oil for cactus mixing instructions
1. Obtaining neem oil that is excessively concentrated, even if it is organic and pure. 2. Prepare 1L of warm water, 1 teaspoon (5ml) of neem oil, and 1-2ml of an emulsifier such light liquid soap or dishwashing detergent. 3. Fill your sprayer with the emulsifier and warm water. Mix well. 4. Fill the sprayer with 1 teaspoon of neem oil, and thoroughly combine. 5. Spray the tops and undersides of leaves, then wait 24 hours to see what occurs. If the spray still works after a week, reapply it and use it on new plants.
The majority of pest problems can be efficiently treated by applying the oil mixture every seven days.
Neem oil with succulents: Does it work?
Although they are tough and able to withstand extreme weather, succulents are nevertheless susceptible to damage from pest infestation, and using neem oil effectively can help prevent such occurrences.
When applied to succulents, neem oil functions as a repellent and a way to stop pests by stopping the hormone that allows insects to feed. The oil’s active component Azadirachtin is responsible for this. For best results, use neem oil twice weekly as a foliar spray or soil drench.
Neem oil, which is derived from the neem plant, can protect your succulent plants from pests without having any negative effects.
Are all plants safe to use neem oil?
Neem oil is therefore a very efficient means of eliminating pests, but can it be applied to any plant? Neem oil can be applied to the majority of plants, but it won’t work on plants with rough surfaces. Neem Oil won’t work on your plants if they have fur, needles, or any other features that might make it easier for pests to hide deeper inside the leaves. Neem oil should not be used to plants with fuzzy leaves, such as the majority of Calatheas.
Neem oil: does it harm plants?
A naturally occurring pesticide called neem is derived from the neem tree’s seeds (Azadirachta indica). Neem trees are indigenous to the tropical jungles of Sri Lanka, India, and Burma. It has been utilized for many hundreds of years as a natural pesticide within the tree’s native habitat. Neem products are now fairly simple to get at most garden centers because to rising demand for organic and less-toxic pesticide alternatives. It might now be the first bottle many gardeners pick up when they encounter a pest problem. Neem can be a useful component in an integrated pest management strategy, provided you know how it works and only use it as directed on the label.
Products made with neem often contain one of two active components. Neem seed oil contains an ingredient called azadirachtin, which is primarily responsible for both killing and repelling insects. Neem oil is transformed into clarified hydrophobic neem oil once the azadirachtin is removed. Azadiractin, which prevents insects from growing and reproducing, is exclusively found in commercial items. The main component of ready-to-use neem oil sprays that may be purchased at a garden center is clarified hydrophobic neem oil.
You can treat some insect and fungus-related diseases with neem oil. It suffocates insects by covering their bodies in oil, which closes off their breathing holes. Against young insects, it works best. Insects that are fully grown adults are usually not destroyed; they are allowed to feed and procreate. Neem oil application timing hence requires careful monitoring of insect lifecycles.
Do not anticipate quick effects, even when neem is administered to insect larvae. Reapplication may be required to completely control bug populations since it can take some time to take effect. Common pests managed by neem pesticide products include aphids, beetle larvae, caterpillars, lacebugs, leaf hoppers, leafminers, mealy bugs, thrips, and whiteflies. Ensure that you can identify insects with certainty and use neem oil only if the pest is mentioned on the packaging. Both pests and beneficial insects can be harmed by neem.
Neem oil can also be used to treat certain fungi-related problems, like powdery mildew. It functions by stopping fungus spores from growing and penetrating leaf tissue. Neem can help prevent the spread of the disease to healthy tissue, but it won’t “treat” a plant that has already contracted a fungal disease.
Products containing neem oil frequently bear labels for a number of different crops, including herbs, vegetables, fruits, nuts, and decorative plants. Neem oil can harm plants by burning their foliage, regardless of the type of plant being treated. Use with caution on recently transplanted plants or other stressed plants. Neem oil must be applied entirely to plants for the pesticide to work, although it is a good idea to test the substance on a small area first. The entire plant can be treated if there are no harmful signs there.
