Description
SPECIFICATION
Process and compositions of producing insecticide coatings
Background
Traditionally, eradication of household insects such as flies, ants, termites, cockroaches, spiders, silverfishes, mosquitoes, beattles etc. has been largely achieved by application of insecticidal sprays, aerosols, fumigrants and baits that kill such insects upon contact or ingestion. These methods are generally effective for a fairly short period of time and have at least the following distinct disadvantages:
(1) Mists and vapors of sprays, aerosols and fumigrants and particles of baits containing active insecticidal agents are high mobile and removable. They therefore cannot stay at desired site for a long enough period of time to perform the desired insecticidal function.
(2) For reason cited in (1), these devices have a relatively short period of insecticidal activities. Practically all of them can only perform their desired function for a period of only several number of weeks. Therefore, repeated applications are necessary to ensure long-term protection against household insects. The need to repeat applications causes great inconvenience and is very time-consuming.
(3) The mobile nature of mists and vapors and particles of these devices create great opportunity of contamination. Such is highly undesirable particularly when such contamination takes place on food or food serving devices.
(4) The fact that once applied the insecticidal agents contained in these devices are only very loosely placed on the surfaces onto which these devices are applied creates undesirable danger as they may contaminate humans and household pets. The absorption of insecticidal agents through inhalation and ingestion over a long period of time may present highly undesirable hazards to human and household mammals.
(5) Applications of these devices are mostly associated with undesirable smell and odor. Such create much inconveniences and may be harmful to health.
(6) Applications of these devices normally are conducted in limited areas. Therefore they cannot be expected to provide maximum insecticidal protection to the premises wherein they are applied.
The invention provides answers to the aforesaid disadvantages of existing insecticidal devices. The invention is a process and via which the possibility to produce a range of insecticide coatings which are to be applied onto surfaces the way one does with paints, varnishes and lacquers, such surfaces could be interior and exterior walls, ceilings, and that of cabinets, wardrobes whether such surfaces are made of concrete, paper, wood, plastic, or ceramic and wh ether they are already painted or not. Once dried, the invention produces a dry, durable, water-resistant coating on the surfaces onto which it is applied. Such coating is odorless and washable.The invention presents at least the following distinct and unique properties which the aforementioned traditional insecticidal devices do not provide:
(1) It is insecticidally effective for several years under normal circumstances while those traditional devices are effective for several weeks.
(2) Insecticidal agents contained in the invention are incorporated into and the particles of which are reasonably firmly held by a continuous film on its surface instead of being mobile and easily removable like that of traditional insecticidal devices.
(3) By virtue of (2), the insecticidal agents stay at place for years until the coating is artificially removed and during which insecticidal activities remain.
(4) By virtue of (2), there are practically no danger of undesirable contamination as the insecticidal agents do not float around uncontrollably like those of insecticidal sprays, aerosols or fumigrants.
(5) The invention produces an end product - continuous coating on a surface, which has no undesirable odor.
(6) The invention may be used to cover most areas in a premises where household insects are problematic and thus provides very much greater protection and coverage in the premises.
(7) The invention produces an end product - continuous coating which does not emit any significant amount, if at all, of mobile particles, vapor, mist or fume that may be inhaled or ingested accidentally by humans or household mammals and therefore greatly reduces the possibility of intoxication over a long term exposure.
(8) The invention is an insecticide coating and is totally different from the conventional type of insecticidal devices commonly available such as sprays, aerosols, fumigrants and baits.
Description of Invention and its Preferred Embodiments
