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. It is a relatively volatile substance and acts as a contact and inhalation agent. [1] [3]
Also, mammals are able to process pyrethrin quickly and have higher body temperatures which prevent pyrethrin from working effectively [22] Although pyrethrin is a potent insecticide, it also functions as an insect repellent at lower concentrations. Observations in food establishments demonstrate that flies are not immediately killed, but are ...
A killing jar or killing bottle is a device used by entomologists to kill captured insects quickly and with minimum damage. [1] The jar typically contains gypsum plaster (plaster of paris) on the bottom to absorb a killing fluid. The killing fluid evaporates into the air and gasses the insect.

Temperatures of −20 °F (−29 °C.) lasting from 48 to 72 hours can kill exposed eggs; alternate periods of freezing and thaw in late winter and early spring may prevent eggs from hatching; and cold, rainy weather inhibits dispersal and feeding and slows the growth of newly hatched larvae.
The temperature within a grain bin must exceed 50 °F (10 °C). The eggs of the moth are grayish white and have a length between 0.3 and 0.5 millimetres (1 ⁄ 64 and 3 ⁄ 128 in). Eggs can be laid directly on the food source singly or in groups of between 12 and 30. A mature female may lay between 100 and 300 eggs at a time. [1]
