The first is by deterring insects from laying their eggs on the pepper due to the effects capsaicin has on these insects. [83] Capsaicin can cause intestinal dysplasia upon ingestion, disrupting insect metabolism and causing damage to cell membranes within the insect. [84] [85] This in turn disrupts the standard feeding response of insects.
Synergists make pyrethrin more effective, allowing lower doses to be effective. Pyrethrins are effective insecticides because they selectively target insects rather than mammals due to higher insect nerve sensitivity, smaller insect body size, lower mammalian skin absorption, and more efficient mammalian hepatic metabolism.

This is a list of films produced by and released under the Walt Disney Pictures banner (known as that since 1983, with Never Cry Wolf as its first release) and films released before that under the former name of the parent company, Walt Disney Productions (1929–1983).

Transfluthrin is a fast-acting pyrethroid insecticide with low persistency. It has the molecular formula C 15 H 12 Cl 2 F 4 O 2.. Transfluthrin can be used in the indoor environment against flies, mosquitoes, moths and cockroaches.
Citronella oil is used especially as a mosquito repellent, [11] particularly for Aedes aegypti (dengue fever mosquito). [12] Research also indicates that citronella oil is an effective repellent for body lice, head lice, and stable flies.
Insect pheromones are neurotransmitters that serve the chemical communication between individuals of an insect species. They thus differ from kairomones, in other words, neurotransmitters that transmit information to non-species organisms. Insects produce pheromones in special glands and release them into the
The tropical wasp Mischocyttarus drewseni coats the pedicel of its nest with an ant-repellent chemical. [184] It is suggested that many tropical wasps may build their nests in trees and cover them to protect themselves from ants.
