Spread the love

Among all plant pests, spider mites (Acari: Tetranychidae) are the most prevalent and devastating. Infestations of spider mites can be eliminated with several commercial chemical insecticides. Does Malathion kill spider mites?

Yes, Malathion, Kill spider mites. Aphids, red spider mites, mealybugs, trips, scales, whiteflies, and other hazardous insects are kept at bay on the designated ornamentals, fruits, and vegetables by Malathion Insect Spray Concentrate.

Spider mites can be seen on the underside of the leaf, opposite the region where the color is lost. Read the complete article to discover more about Malathion and how it gets rid of spider mites.


Malathion, an artificial organophosphate, is a typical insecticide for spider mites and other pests that damage vegetables, fruits, shrubs, and landscaping plants.

Other insecticides used on pets and indoors to control insects including ants, fleas, and ticks also include malathion. Fyfanon and Atrapa are two mosquito-controlling treatments that contain the active component malathion.

A petroleum solvent, such as kerosene, may be used to dilute pesticides prior to application; in this situation, the petroleum solvent would make up the majority of the pesticide solution.

No pesticide exposure is risk-free since pesticide products are intrinsically harmful. A person’s risk of having adverse health effects from exposure to any pesticide, including Malathion, mainly depends on how much of the pesticide they come into contact with and for how long.

What Causes Spider Mites To Produce?

Large amounts of nitrogen produce abnormal proteins, which don’t benefit the plant but make plant sap sweeter, encouraging the growth of sucking insects like spider mites.

To prevent spider mites—the majority of spider mite species like hot, dry weather—apply a balanced range of nutrients and only what the plant needs. As one may have guessed, spider mite infestations are frequent during times of dryness. Indoor plants that aren’t getting enough water are more likely to have spider mites.

Spider mites are especially hard to control on larger plants and in areas with lots of plants. When more plant tissue is available for them to dwell on and feed on, it is harder to detect and cure spider mite infestations.

Overfeeding plants with nutrients can also increase their susceptibility to spider mites. If too much nitrogen is applied to plants, spider mites and other pests are more likely to attack them.

Does Malathion Kill Spider Mite Eggs?

No, Malathion does not kill spider mite eggs. Because of the distinctive design of the eggshell, which is made up of several layers that have evolved to restrict water loss while also allowing the embryo to breathe, eggs are difficult to kill.

It has been demonstrated that the eggshell is a highly effective barrier against Malathion.

Only the airplanes and micropyles, which appear to be too few in number or too small in size to allow enough insecticide to pass through the eggshell, can allow the penetration of insecticides into the insect eggshell. Failures to manage insect eggs can also be attributed to resistance.

Many insect species have been known to develop resistant eggs. A few investigations have revealed that some insect eggs produce an excess of the enzymes needed to break down insecticides.

Does Malathion Kill Red Spider Mites?

Malathion applications successfully managed the red spider mite infestation. Malathion was the most effective insecticide used singly, whereas deltamethrin was the least successful at controlling the red spider mites.

Especially the Spectracide Malathion Insect Spray Concentrate is designed to guard against red spider mites, thrips, mealybugs, whiteflies, scales, and further identified undesirable pests on the ornamentals, fruits, and vegetables listed. It kills the insects listed on fruits, vegetables, roses, shrubs, and flowers.

Do not let Malathion enter or runoff into drainage ditches, gutters, storm drains, or surface rivers in order to preserve the environment. An Insect Spray Concentrate, Ortho MAX Malathion is designed to cure red spider mites, as stated on its label.

How Long Does It Take Spider Mites To Die With Malathion?

Malathion Kill the spider mites within mins. Control Solutions Inc. makes the highly concentrated pesticide malathion 57%, which is used to defend crops and other vegetation against various plant-eating spider mites. Insects are killed by Malathion, an organophosphate that damages their nervous systems and renders them dead in minutes.

Malathion 57% should be applied with a professional skid sprayer, a backpack sprayer, or a hand-held pump sprayer. Malathion is typically applied to vast croplands using a professional skid or boom sprayer. We advise using a 1-gallon pump sprayer for modest fly control applications.

On broad land areas with trees, grasses, fruit, vegetable, and non-bearing crop plants, malathion 57% is particularly intended for application with a professional skid sprayer. Before administering Malathion, be sure to read the label because when to apply it depends on when the crop you wish to treat is harvested.

Will Malathion Damage Plants In Which Spider Mites Live?

Yes, Malathion is one of the most widely used broad-spectrum pesticides because, although harmful to bees, butterflies, and other helpful species, it quickly breaks down in the presence of heat and light.

Malathion, however, can seriously harm or even kill many landscaping plants in which spider mites live.

Woody shrubs like camellia, azalea, hibiscus, podocarpus, Ixora, touch, aralia, poinsettia, cassia, ligustrum, gardenia and several rose types are among the plants that are vulnerable to Malathion damage.

Intolerant herbaceous species include kalanchoes, coleus, dieffenbachia, and ferns such as Boston, staghorn, and maidenhair. Fruiting plants affected by Malathion include edible figs and some citrus. The phytotoxic effects of Malathion on various holly trees and bushes are also noteworthy.


Therefore, after reading the whole article, you are now aware that Malathion kills spider mites. Although malathion is recommended for use on spider mites, it often only kills a small portion of the spider mites.

Malathion, however, does not harm spider mite eggs. Eggs are challenging to destroy because of the peculiar form of the eggshell, which is composed of multiple layers that have evolved to limit water loss while simultaneously allowing the embryo to breathe.

However, malathion can seriously harm or even kill a lot of landscaping plants that contain spider mites. Among the plants that are susceptible to Malathion, harm is woody shrubs and several rose varieties.
