Mealybugs are small, white insects with a white, waxy, fluffy coating that make them look like specks of cotton. They form colonies and destroy plant tissue by feeding on plant juices. They secrete honeydew -- a sticky substance which attracts sooty mold and ants. White cottony areas are where they incubate their eggs.

10 Common Houseplant Pests and Their Solutions
Contact your local county Extension office through our County Office List. Print this fact sheet. Brown soft scale Coccus hesperidum is the most important scale insect that occurs on indoor grown plants in Colorado. When feeding it excretes a large amount of sticky honeydew that can cover leaves and create serious nuisance problems.
Heavy infestations can cause leaves to prematurely shed, and branches to die back. Brown soft scale occurs worldwide and has an enormous range of recorded host plants, including families of plants in genera.
Brown soft scale is only known to occur on indoor-grown plants in Colorado, but occurs year-round on many kinds of landscape plants in areas within the United States that have milder winters.
Indoor-grown plants most commonly infested in Colorado include citrus, Schefflera , Ficus , English ivy, and bay leaf. Brown soft scale is found on both stems and leaves. When full-grown it is about mm long ca. The body is quite flat, appearing only slightly domed when viewed from the side. Color ranges from yellow-green to yellow-brown and scales may be mottled with some brown spots. Older scales usually become darker brown.
Only females are produced. When mature, the mother scale produces eggs that hatch within her body, producing very tiny 0. Crawlers may live for a few days under the protective cover of the mother scale, but later move to colonize other areas of the plant. Stems of plants are usually favored sites where brown soft scales will settle, but they also can occur on leaves.
The crawler period is the most mobile stage of the insect and is the stage that would infest new plants. Crawlers can be moved and carried while handling infested plants and may be able to be blown short distances. After the crawler has settled it begins to feed with its piercing-sucking mouthparts. These are used to reach the sugar-rich fluids present in the phloem vessels of the plant. As they feed, the scale insects excrete excess water and sugars, producing honeydew , a sticky, shiny fluid.
Within a week or two after birth, the scale will molt to a second stage, which is still quite small, only about 1. During this period the scale will normally remain in place, but can still move. The second stage of brown soft scale may last for about weeks followed by a final molt to the adult form. The adult form grows considerably as it produces and matures eggs, doubling in size within a couple of weeks.
Once females begin to reproduce they do so continuously, so that a few crawlers will be produced daily over weeks or more, after which the female dies. On indoor plants multiple generations will be produced each year. Because the scales are laying eggs over an extended period, generations overlap and there will be no distinct annual peaks in egg production and new crawlers.
Early detection can greatly improve the ease of managing brown soft scale. The insects can be difficult to detect since they are small and may blend in well with the plant. However, the honeydew they produce while feeding provides an excellent means to easily detect the presence of this insect. The honeydew produced by brown soft scale may pool next to the insect. Often, the honeydew is ejected, sometimes over an inch or more away from the body, and ultimately lands on a leaf below or aside the insect.
By regularly checking plants every couple of weeks, early infestations can be recognized by the presence of the honeydew this insect produces. Monitoring for honeydew can also be useful to determine if insecticides have been effective.
Since the scale insects will often remain attached to the plant after death, the detection of honeydew can be evidence that the insect is alive and continuing to feed. Note: There are other insects occurring on houseplants that also produce honeydew. Aphids are perhaps most common. Mealybugs and other kinds of soft scales, such as hemispherical scale Saissetia coffeae and nigra scale Parasaissetia nigra , also excrete honeydew.
Biological Control. In outdoor settings there are often numerous natural enemies that attack and greatly limit brown soft scale. Most important are several types of small parasitoid wasps that develop within the body of the scale, ultimately emerging through a hole they cut in the back of the body.
Presently there are no reliably effective natural enemies available to control brown soft scale indoors. Generalist predators such as larvae of green lacewings and the predatory beetle Rhyzobious lophanthae will feed on brown soft scale and may help reduce numbers of the scale in some situations. However, if large amount of scales are present and large amounts of honeydew are covering the plant these natural enemies will not be effective.
If it is practical to move plants outdoors then some biological control can occur by some of the generalist natural enemies that are normal residents in yards — lady beetles, green lacewings, various predatory flies and other beneficial insects. Moving plants outdoors also allows plants to be easily sprayed and washed so that they honeydew can be removed.
Insecticide Options Indoors. There are several insecticides that can be used to control brown soft scale Table 1. Insecticidal soaps potassium salts of fatty acids can be used as dilute sprays. Insecticidal soaps will only kill insects that can be covered during application but are usually very effective against the first stage crawlers.
Since insecticidal soaps can only kill insects contacted during application, t reatments will need to be reapplied to kill insects that were not exposed during application, including later hatched crawlers. Insecticidal soaps can be used on edible plants e. Several kinds of horticultural oils are available to be used to control insects and mites on plants. Horticultural oils primarily kill the insect by smothering, blocking the small openings through which it breathes. Commonly available horticultural oils are either mineral oils or neem seed oils.
Horticultural oils will only kill insects that can be covered during application. Stages of the scale will remain that cannot be killed in a single spray, such as crawlers that remained protected under the cover of the mother scale or newly laid hatched eggs. To be effective for control of brown soft scale, oil sprays will need to be repeated several times. Horticultural oil products can be used on edible plants e.
Soil-applied systemic insecticides can be used on some plants. The insecticide imidacloprid can move systemically within plants and may provide excellent control of brown soft scale.
Houseplant products containing imidacloprid are applied to the soil as granules or a drench, then watered into the soil so that it can be picked up by roots. At present January there are two imidacloprid products labeled for indoor use on houseplants: Bonide Systemic Houseplant Insect Control 2. Neither of these products allow use on indoor grown food crops — such as citrus being grown for fruit and herbs. Horticultural oils and insecticidal soaps remain the only options for control of brown soft scale when food crop plants are grown indoors.
Insecticide Options for Outdoor Grown Plants. If plants are moved outdoors during the warmer months, and are then grown as an outdoor ornamental plant, a few other insecticide options exist. These primarily include sprays of various pyrethroid insecticides, such as cypermethrin, cyfluthrin, lambda-cyhalothrin, and permethrin. These have ability to persist on the plant for several days, providing better ability to kill the young crawler stages of the scale.
However, pyrethroid insecticides usually cannot control older scales that have developed a protective waxy cover. Alternately, sprays of certain systemic insecticides, containing imidacloprid or acetamiprid as the active ingredient, can also be used on outdoor grown plants, and these can also provide good control of all stages of brown soft scale. Label instructions for most of these products limit their use to ornamental plants and they cannot be used on plants with fruit or foliage that is edible.
Table 1. Some insecticides that may be useful to help manage brown soft scale on houseplants when grown indoors and when grown outdoors. Other unlisted products may exist that can also be used. Always check the label instructions when using any pesticide.
All pesticides can only be used in a manner that is consistent with the use directions of the pesticide label. The original version of this publication was produced by R. Revised by W.

How to Get Rid of Soil Mites
Gnats in houseplants are annoying. While they look similar to mosquitoes, they don't bite. Because gnats in houseplants typically result when the potting mix contains too much moisture, the best way to prevent gnats from taking over your home is to avoid over-watering in the first place. But what if the damage is already done and you're dealing with a swarm of pesky flies surrounding your plants? Here, we walk you through the best ways to get rid of gnats in your house plants. One way to tell if you're about to run into a gnat problem is to look for eggs. Fungus gnats lay eggs in the soil and these eggs become larvae, which feed on fungi in the soil of plants. In addition to fungi, they also like organic matter and will sometimes eat plant roots or seedlings, and the plant will appear wilted.
How to get rid of fungus gnats on indoor plants
If you have houseplants, then you know how hard it can be to keep them alive. A houseplant, on the other hand, is completely your responsibility. You have to prune it, water it, feed it and make sure it gets the sunlight it needs. We want to introduce you to these pests, so you know exactly what to keep an eye out for if your houseplants start looking a little grim. One of the most common pests that might be harming your houseplants are mealybugs.
Clover mites are relatively harmless while red spider mites are a garden pest that you will need to control.
Indoor Plant Insects
Contact your local county Extension office through our County Office List. Print this fact sheet. Houseplants are susceptible to attack by many insects and mite pests. Some of these houseplant pests can cause extensive damage to the appearance and health of the plant while others are simply a nuisance. Infestations of scale insects mealybugs and whiteflies are almost always established from infested plants recently purchased or received as gifts. As a precaution, all new plants should not be placed with existing houseplants for at least three weeks.

Last Updated on October 23, by Grow with Bovees. If you look at the potted plants in your home closely, sometimes, you may notice tiny white dots moving on the top of the soil or along the edges of the pot. This could be an indication that you have a soil mite infestation. While, in general, soil mites are harmless to the soil and the plants, they are pests and their existence in your precious plants may bother you. So, if you want to eliminate soil mites, there are many ways in which you can do that. Soil mites are scavengers that usually make their home in potting soil or compost heaps because they are attracted to organic, rotting matter such as leaves, moss, wood, etc. Soil mites can travel from your outdoor spaces to inside your home and move around in your home, patio, etc.
You know the feeling. Could it be watering? A draft? Too much sun or not enough?
