The safest effective way to control scale is with a horticultural oil spray.

People also ask, how quickly does malathion work?

The time it takes for malathion to break down to half of the original amount in soil is about 17 days, depending on the soil type. This length of time is known as the half-life. In water, malathion has a half-life between 2 and 18 days, depending on conditions like temperature and pH.

Likewise, how do I get rid of scale on my plants? To get rid of scale insects prune and dispose of infested branches, twigs and leaves. When scale numbers are low they may be rubbed or picked off of plants by hand. Dabbing individual pests with an alcohol-soaked cotton swab or neem-based leaf shine will also work when infestations are light.

Will rain wash off malathion?

However, because Guthion is highly toxic, it does not require reapplication after precipitation as soon as some of the other insecticides.
