They have been used in companion planting as pest control in agricultural and garden situations, and in households. Certain plants have shown effectiveness as topical repellents for haematophagous insects, such as the use of lemon eucalyptus in PMD, but incomplete research and misunderstood applications can produce variable results.

The cutworm larva of the large yellow underwing (Noctua pronuba) Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm.
Most notably, the variegated cutworm is known as one of the most damaging garden pests. The larvae cause considerable damage to common garden vegetables and fruits, destroying large amounts of crops every year. [1] There are many methods of pest control that are being implemented in order to control P. saucia and its damage to crops. [2]
Agrotis ipsilon, the dark sword-grass, ipsilon dart, black cutworm, greasy cutworm or floodplain cutworm, is a small noctuid moth found worldwide. [2] The moth gets its scientific name from black markings on its forewings shaped like the letter "Y" or the Greek letter upsilon . [ 3 ]
Outside the United States, chlorfenvinphos, registered under the trade names Birlane, C8949, CGA 26351, Sapecron, Steladone and Supona, was used as a soil insecticide for controlling root maggots, root worms and cutworms. Chlorfenvinphos was also used against Colorado beetles on potatoes and scale insects and mite eggs on citrus.
Dichlorvos (2,2-dichlorovinyl dimethyl phosphate, commonly abbreviated as an DDVP [1]) is an organophosphate widely used as an insecticide to control household pests, in public health, and protecting stored products from insects. The compound has been commercially available since 1961.
In her book “Silent Spring”, published in 1962, Rachel Carson documented the perils of insecticides and particularly DDT, ultimately saving the American bald eagle from extinction.
Insecticides are pesticides used to kill insects. [1] They include ovicides and larvicides used against insect eggs and larvae, respectively. The major use of insecticides is in agriculture, but they are also used in home and garden settings, industrial buildings, for vector control, and control of insect parasites of animals and humans.
