Best Way to Kill Insects in the House
Calibration insects are subversive houseplant pests that wait like minor bumps on plant stems and leaves. Scales can exercise a lot of harm to houseplants and outdoor plants. The pesky scale bugs bite into plants to feed on the sap, resulting in discolored leaves, leaf drop and stunted establish growth.
Scales are small bugs in the insect order Hemiptera. There are 8,000 species of scale bugs. Their name comes from the scale-similar waxy roofing that many species of calibration insects take.
Most types of scale insects have oval-shaped bodies. Scales are crawling insects that can't fly, and they infest plants by moving from ane to another. Calibration insects do harm to plants by their mouths, which pierce plant tissue and suck sap.
In this guide to scale insect control, you lot will find out how to get rid of these plant-destroying bugs on houseplants and outdoor plants.
What do Scales on Plants Look Like?
Scale insects include many species that range in color and size and look like round bumps on the plant
Scale insects on plants await like small-scale brown or cream-colored bumps that are easily mistaken for plant growth. Calibration bugs are plant pests with round or oval shape and range in size from minuscule dots to large lumps. When scales achieve adulthood, they don't move on plants, making them hard to identify.
Looking at pictures of scale bugs, recognizing them equally insects can be tricky. Their shiny oval bodies adhere to plant stems or leaves. The scales can be tiny pests, measuring 2 mm, or larger bugs upwardly to v mm in diameter.
In fourth dimension, scale insects clump together on stems, looking like lumpy plant growth. Even though the bugs don't look like they are moving, they are constantly feeding on the constitute'due south sap. Looking closely, you will as well see a sticky liquid on the round shiny bodies that the sap-sucking bugs use as protection.
Male scale insects await entirely different from female scale bugs. The males wait more like tiny flies. Notwithstanding, because they only live for a few days, you will rarely see these pests on plants.
Life Wheel of Scale Insects
Scale life bicycle starts as an egg before going through ii growth stages and so becoming an adult
The life cycle of scales starts equally an egg before going through two growth stages (instars) and maturing as adults. A Mature female scale produces eggs that hatch into yellowish nymphs (starting time instar) that crawl to observe a identify on the found and so stays there feeding into adulthood. The bugs might never motion from that spot.
It's during their adult stage when scale bugs practice the almost damage. The female insects stay at the same spot, sucking the constitute'south sap. During this fourth dimension, chocolate-brown or white scales appear on the bugs for protection. The females lay eggs, which are subconscious under their bodies. When the minuscule insects hatch, they crawl to some other place on the found.
But because in that location is generally no motion through their life cycle, identifying scale insects is tricky.

Types of scale insects
Three types of scale tin can affect houseplants:
- Armored scale bugs—These scale insects have a round, oval shape, and hard shell cover. The tiny sap-sucking pests hide nether their protective calibration while feeding and laying eggs.
- Soft scale insects—These subversive pests are larger than armored scale. They have a soft, furry covering and—unlike armored calibration—produce honeydew from plant sap.
- Mealybugs—These nasty fiddling houseplant pests crawl on plants leaving a cottony-wool like substance behind. Mealybugs also secrete honeydew and cause sooty mold.

Calibration Insect Impairment on Indoor Plants
The most apparent damage that scale causes on houseplants is weak or stunted growth. Other signs of damage on calibration-infested plants are xanthous leaves, dark-brown leaves, leaf drop, and dead foliage or stems. If left untreated, scales tin eventually cause plant death.
The types of institute damage caused by scale insects include:
- Xanthous leaves—Scale damage usually causes plant leaves to be yellowish and wilted as if the plant is suffering from a lack of water.
- Premature leaf drop—The impairment on the constitute acquired by the sap-sucking bugs causes weak growth. The result is that leaves don't go the nutrients they crave and finish up dropping off.
- Black sooty mold—Honeydew excreted by scales causes black mold to grow on leaves. This substance affects photosynthesis, causing the plant to lack the nutrient requires for healthy growth.
