The invention specifically relates to insecticidal compositions with most or all the aforementioned desired characteristics and with long term effective pest control.
Discussion of Prior Art.
Crawling insects have a long history as a major problem to mankind. These insects have been controlled in many ways including the use of insecticidal composition. There are a number of attempts to prepare insecticidal compositions for control of such crawling insects. Considerable effort has been put to into the development of a long lasting insecticidal composition. However, there have many difficulties that have been experienced in producing an optimum insecticidal composition with 10 desired characteristics by the users.
The major requirement of any long lasting and effective insecticidal compositions is the chemical stability to ensure efficacy and uniform activity. However, safety must come high on the list of important attributes of a good insecticidal composition.
Other important attributes include worker exposure, safety for the
Environment, including spills and container disposal issues. Most of these chemicals are applied under furniture and craves or cracks which occasionally come into contact with people. For formulation to be safe they need to be physically stable and this includes separation or breakdown of the product, which affects any of the other properties.
Another desirable property includes the ability to not leave any marks or stains on furniture or walls where it is applied. The other properties desirable for such formulations also include the ability to withstand low or high temperatures without affecting the loading of the active ingredient. This includes melting at high temperatures and crystallization during low temperatures. The formulations must be useable without excess forming or bad smells or odours, be compatible with
other commonly used pesticides and at the same time maintain the biochemical activity.
The insecticidal composition has to be ^f^toifeeφaefcaglfS'ϊn' conventional
Many of the insecticidal compositions used today have quite a number of undesirable characteristics. Firstly many of them are made up with materials that when applied will always leave ugly marks or sports where they were applied. This is not a desire attribute to the users. The other problem of known convention and composition are made up of rough materials and desired means of application like the syringe applicator or tube with a long nozzle cannot be used to apply such compositions.
Other compositions are effective but are harmful to the environment or unsafe when exposed to workers or the people living in homes where such compositions are used.
An object of the instant invention is to provide an insecticidal composition that has most or all the aforementioned desired properties.

Boric acid is often used as
a rel^^h^eno^ogci^i^^eitide for the control of the cockroaches, termites, fire
ants, WsS^Baasa^Ff^oXher insects and is an active ingredient of many commercial insecticide formulations.
As an insecticide, boric acid acts as a stomach poison, affecting the insect's metabolism and protoplasma. Boric acid is generally known as a desiccant; in other words it kills by removing the moisture form the body of the pests, causing severe dehydration, which will affect electrolyte metabolism with the potential of metabolic acidosis.
Ingestion of boric acid causes insects deaths, three to ten days later, of starvation and dehydration. Due to its unique mode of action, insects do not develop resistance to borates. Boric acid/Borates are very effective against many crawling insects' pests including cockroaches, silverfish, larder beetles, carpenter ants and other woodborers as well as organisms causing wood decay.
Baits containing boric and food ingredients work on a simple principle, attract the cockroach with a promise of easy food; when it eats the food, it also ingests a poison.
For best results, clean, clean the area to be treated. Apply the paste with a stick; smear it on the surfaces in the corners of rooms, shelves, cupboards drawers, and other hidden dark places of the infested areas.
he Boric acid paste can be applied in domestic ^emis^P,J^βά$L%ndli,
Boric acid naturally occurs in air, water (surface and ground water), soil and plants, including food crops. It enters the environment through weathering of rocks, volatilization from seawater and volcanic activity. Most boron compounds convert to boric acid in the environment, and boric acid is the boron compound of environmental significance. Boric acid is adsorbed to soil particles and aluminum and iron minerals.
Experiment 1
The efficacy of the above preparation was tested in five houses. The insecticidal composition was smeared on a flat surface - such as on a small piece of paper with approximately 5gm-10gm of the insecticide. It was then placed in the kitchen corners and other hidden spaces in four houses. The fifth house acted as a control. No insecticide was placed there. The cockroaches that died were young ones basically nymphs.
The results are shown in the following table: -
COCKROACHES DEAD
HOUSES DAY 1-6 DAY 7-14
1 0 8
2 0 3
3 0 2
