How to protect papyrus, paper (and later parchment) collections from bugs is a topic that already Aristotle was interested in and that kept librarians busy through the centuries. [ 19 ] The term bookworm is also used idiomatically to describe an avid or voracious reader, [ 20 ] or a bibliophile .
Propoxur (Baygon) is a carbamate non-systemic insecticide, produced from catechol, [2] and was introduced in 1959. It has a fast knockdown and long residual effect, and is used against turf, forestry, and household pests and fleas.
Diazinon is a contact insecticide which kills insects by altering normal neurotransmission within the nervous system of the insect. As mentioned above, diazinon inhibits the enzyme acetylcholinesterase (AChE), which hydrolyzes the neurotransmitter acetylcholine (ACh) in cholinergic synapses and neuromuscular junctions .
[1] Like other pyrethroids, bifenthrin is chiral; it has different enantiomers which can have different effects. Bifenthrin is found in two enantiomers: 1S-cis-bifenthrin and 1R-cis-bifenthrin. 1S-cis-Bifenthrin is 3-4 times more toxic to humans than 1R-cis-bifenthrin, while the latter is more than 300 times more effective as a pesticide.

Contact paper is essentially decorative paper that comes in giant rolls that you can cut down to a size that fits a wall, the floor, your laptop, desk, treadmill, cabinets—you name it. ...
It is effective on contact and via stomach action. [1] Because imidacloprid binds much more strongly to insect neuron receptors than to mammal neuron receptors, this insecticide is more toxic to insects than to mammals. [3] From 1999 [4] through at least 2018, [5] [6] imidacloprid was the
Cyhalothrin (ISO common name [3]) is an organic compound that, in specific isomeric forms, is used as a pesticide. [4] It is a pyrethroid, a class of synthetic insecticides that mimic the structure and properties of the naturally occurring insecticide pyrethrin which is present in the flowers of Chrysanthemum cinerariifolium.
Deltamethrin is a pyrethroid composed of a single stereoisomer, of a possible 8 stereoisomers, selectively prepared by the esterification of (1R,3R)- or cis-2,2-dimethyl-3-(2,2-dibromovinyl)cyclopropanecarboxylic acid with (alpha,S)- or (+)-alpha-cyano-3-phenoxybenzyl alcohol or by selective recrystallization of the racemic esters obtained by esterification of the (1R,3R)- or cis-acid with the ...
