Boric acid is a slow-acting, non-toxic inorganic insecticide that has been used for urban pest management due to its low absorption and mammalian toxicity. After World War II, organic insecticides replaced inorganic ones due to their faster kill but increased risks. Recently, insecticide baits have been more commonly used in integrated pest management programs. Cow's milk and flour have been evaluated as natural alternatives to synthetic pesticides against rose pests and have shown effectiveness against aphids and mites when applied in the morning. Epsom salts can also kill cockroaches by upsetting their biological systems.

(Fail et al. 1998, Hubbard 1998, Wester et al.

1998) Boric Acid (H3BO3) dust, a nonvolatile, slow-acting


inorganic insecticide, has long been used in urban pest management (Ebeling 1995). Negligible absorption of
boric acid through unbroken skin and relatively low mammalian toxicity have contributed to its favorable
safety record as an insecticide.

(Appel 1990, Reierson 1995). After World War II, the use of inorganic insecticides in structural pest
management gave way to organic, neurotoxic compounds that provided much faster kill. For almost 40 years,
conventional cockroach management has thus shifted to greater reliance on spray applications of residual
formulations of broad-spectrum organic insecticides, primarily organophosphates and pyrethroids. In the last
two decades, however, insecticide baits have largely displaced other formulations for control of German
cockroaches and other structural pests, especially as components of integrated pest
management (IPM) programs

(Garima Gupta, Gaganpreet Kaur and Neelima R. Kumar 2015) Recent pest management approaches
are focusing more towards natural and safer control measures especially on ornamentals and green
houses, where a lot of dependency prevailed on synthetic pesticides. Cow’s milk, if as a curative
measure could get incorporated in this system, would be a safe approach. In current research, cow milk
was evaluated with toxicity bioassays against three pests of rose (aphids, thrips & spider mites) and for
influence on two predatory insects (lady bird beetles & minute pirate bugs).

(Stoll 2005). Flour mixed in water is said to be very effective against aphids and spider mites. It should be
applied in the morning taking care to spray underside of leaves. As the heat of the sun increases, the mixture
dries out and the insects are left encrusted in flour, shrivel and die. The coating of flour falls off the leaves so
that their ability to photosynthesise is not essentially affected

According to (Ellis and Bradley 2007) starch like ordinary baking flour is an old pest control remedy, whereas
numerous products made as non poisonous insect control from potato starch, are currently on the market in
the US and India. Reportedly potato starch apart from killing aphids, red spider mites, white flies and thrips
also acts as an inhibitor to downy mildew on cucumbers in glasshouses.

(Zhang, & Dai, 2010). In the quest of finding non-toxic insecticides which could eventually substitute
toxic insecticides and at the same time overcome the limitations caused by the existing bioinsecticides.
Jiaotou (chinese onion) may be a valuable material on the search of compounds, which could be used
for the development of new insecticides and antimicrobials. Pseudomonas aeruginosa and Aspergillus
niger have already been found susceptible to the diluted essential oil of A. sphaerocephalon L. subsp.

(Dr. Robert Stauffer 2009) The magnesium in the Epsom salts will upset the biological system of a
roach and prevent feeding; therefore, the roach will die.
