Boric acid is effective at getting rid of roaches, but it needs to be applied correctly. When a roach walks through an area treated with boric acid, the dust clings to its body, later attacking ...
Boric acid is not a bait in the dry form, but rather broadcast as a dust, that is both a toxin and a desiccant. Boric acid is often formulated into a paste. Roach attractants are mixed with the boric acid. It is similar in consistency to toothpaste. Boric acid roach baits consist of a proprietary blend of attractants.
Boric acid is a weak acid, with pK a (the pH at which buffering is strongest because the free acid and borate ion are in equal concentrations) of 9.24 in pure water at 25 °C. But apparent p K a is substantially lower in swimming pool or ocean waters because of interactions with various other molecules in solution.
Poisoned bait containing hydramethylnon or fipronil, and boric acid powder is effective on adults. [84] Baits with egg killers are also quite effective at reducing the cockroach population. Alternatively, insecticides containing deltamethrin or pyrethrin are very effective. [84]
Scientists at Heriot-Watt University in Edinburgh have developed the new technology which targets the pests within 1.2 metres of accuracy.
Hydramethylnon (AC 217,300) is an insecticide used primarily in the form of baits for cockroaches and ants. [1] [2] [3] It works by inhibiting complex III in the mitochondrial inner membrane and leads to a halting of oxidative phosphorylation (IRAC class 20A).
