The scale insects are Hemiptera spp.They are small and flat.They are part of the true bug family.It is important to know how to get rid of these pests because they can ruin your garden.
Step 1: There are adult scales.
Scales can be off-white, tan or brown.Some may look cottony or fluffy, but most of them have a smooth, flat covering.The adults don't move.
Step 2: Mention the names of thecrawlers.
The young scales, called crawlers, have legs and will move very slowly, or be blown by the wind, to a spot on a plant that they like.The adults of the species are often not the same color as the Crawlers.The cushion scales are off-white but the crawlers are orange.The crawlers will lose their legs after attaching to the leaf or stem.
Step 3: Scales can get on a plant.
They pierce the plant with their mouths and take the juices out.Scales can become a problem for gardeners around the world.When the weather warms, they reproduce on the plant leaves and stems and make a meal out of any nearby garden plant.
Step 4: There are signs of scale damage.
The first symptoms are yellow.twigs and limbs die and the tree bark cracks.Soft scales don't do enough damage to kill a plant.honeydew is the most serious problem they cause.Aphids excrete honeydew as well.They can be green or red and are more mobile than scale insects.Dark spots on the leaves can be caused by sooty mold, a fungus, which can grow on honeydew.
Step 5: Remove the scales from your plant.
Even if plants are never put outdoors, scales can attack them.They are often overlooked at the greenhouse or store where the houseplant is purchased and brought home.Scales can be removed by rubbing them off with an old toothbrush, cotton swab or thumbnail.
Step 6: It is possible to use insecticidal soap.
It is possible to kill scales with insecticidal soap.1 gallon of water is enough to mix about 5 liters of insecticidal soap or a very mild dish soap.When the soap solution begins to drips, spray the plant, including the undersides of the leaves and stems.The scales should be gone by the time the treatment is over.
Step 7: Do not use regular house soap.
Laundry soap, automatic dishwasher soap and highly concentrated dish soap should not be used.They can damage the leaves.
Step 8: When fighting a small-scale attack, use the same methods as for houseplants.
Scales are most prevalent outdoors where they attack all types of trees, shrubs, perennial plants and annual plants.Scales can be removed the same way you would houseplants if the plants are small enough.Use an old toothbrush or nail to scrub the scales off.The plant can be sprayed with an insecticidal spray.
Step 9: Take away parts of the plant that have scales.
Cut off branches and leaves which hold high concentrations of insects when the scale is severe.Pruning can be done at the base of the branch or above a leaf.Use a garden hose to spray off the pruners or loppers before using them on another plant to remove any scale insects that may be left on them.
Step 10: The plants should be sprayed with oil.
Summer oil is used to kill scale insects.The leaves and stems should be sprayed with oil.All of the formulas on the market are equally good.The rate at which they are mixed varies.Follow the manufacturer's recommendations with care.The oil should be mixed with the water by shaking the spray bottle vigorously.
Step 11: The seasons should be kept in mind.
If you want to kill scale insects that have survived the winter, spray the plants early in the spring.If scales return after the early spring treatment, spray the plants in June, July and August.The scale insects that are on the plant are smothered by the Horticultural oils.After a week or two, the treatment may have to be repeated.
Step 12: Try the spray on a leaf.
To make sure the plants are not sensitive to oil, wait 24 to 36 hours.Some plants can be damaged by oil.Go ahead and spray the whole plant if the leaves don't appear to be damaged.
Step 13: Avoid windy days.
When it is windy, do not spray plants with oil because the oil could drift to other plants that don't need to be sprayed.
Step 14: When the leaves are wet, do not spray plants.
The oil could be washed off before it kills the scales, because it won't make good contact with the plant.
Step 15: The oil should not be used on humid days.
When the relative humidity is over 90 percent, horticultural oil should not be sprayed on plants.Plants can be damaged if the temperature is over 100 F.The oil will not cover uniformly if the temperature is below 40 F.
Step 16: The oil should not be used on certain plants.
Plants with stressed leaves are more likely to be damaged when sprayed with oil.Young, new plant stems and leaves are likely to be damaged by spray oil.Plants that have been treated for diseases with sulfur should not be treated with oil.The oil could cause a reaction in the plant.
Step 17: When using the oil, wear protective glasses.
It's not very harmful to people or animals, but it can cause irritation to the eyes and skin.
