  • the composition may be used on hard surfaces in homes like those on utensils, furniture, floors, walls, and toilets and on soft surfaces like clothes, upholstery, bedsheets and blankets.
  • the use of the composition on such surfaces ensures long lasting cleaning and control of insects from being attracted to such surfaces for up to 24 hours after the surface is cleaned.
  • the present inventors while trying to solve the above problem have hit upon a combination of a Bacillus bacterial spore and a select essential oil constituent in a surfactant containing composition which not only ensured excellent cleaning and insect control immediately after the cleaning action but ensured that the surface continues to remain clean and is efficient in preventing insects from being attracted to such surfaces, for a long time thereafter.
  • WO2021/240315 discloses a a probiotic Bacillus surface sanitizer comprising a sanitizing agent, a probiotic Bacillus sp. and a surfactant, but excluding any stabilizer, as well as a process for manufacturing the probiotic Bacillus surface sanitizer.
  • W02021/094091 discloses a perfume carrier composition comprising bacterial spore and at least one fragrance, wherein the at least one fragrance is at least partially adsorbed to the bacterial spores.

  • Bacillus bacterial spore is a combination of bacterial spores of Bacillus amyloliquefaciens, Bacillus megaterium, and Bacillus subtilis.
  • any feature of one aspect of the present invention may be utilised in any other aspect of the invention.
  • the word “comprising” is intended to mean “including” but not necessarily “consisting of” or “composed of”.
  • the term “comprising” is meant not to be limiting to any subsequently stated elements, but rather to optionally also encompass nonspecified elements of major or minor functional importance. In other words, the listed steps or options need not be exhaustive. Whenever the words “including” or “having” are used, these terms are meant to be equivalent to “comprising” as defined above. It is noted that the examples given in the description below are intended to clarify the invention and are not intended to limit the invention to those examples per se.
  • the present invention relates to insect control.
  • Insect control as per the present invention is different from insect kill or (or insecticidal action) or insect repellency.
  • insect kill or insecticidal action the active used is very potent and is used to kill insects.
  • insect repellency is meant that the active is applied such that the smell or vapours of the active cause the insects to be repelled such that they are prone to moving away from the treated area.
  • the present invention uses a different approach which is relatively safer and uses very mild actives.
  • insect control as per this invention, is meant that the treated surface is so cleaned that the insects are not attracted to such a surface for a long time after the cleaning action..
  • Insects which may be controlled from the various surfaces which are cleaned using the composition of the invention include crawling insects like ants, cockroaches, dustmites, silverfish, bedbugs and termites. Additionally, the composition especially on dishes and utensils can be used for controlling flying insects like flies. These insects are either a nuisance or cause health hazards e.g. ants colonise the kitchen and other areas and contaminate food. Cockroaches cause and spread diseases, while bedbugs cause itching and asthma. Dust mites are well known to cause allergies while termites damage furniture. Houseflies are known as vectors for various diseases. Thus, consumers wish to use cleaning products for cleaning surfaces and clothes and other fabrics at home which not only clean but also control insects for a long time e.g at least 6 hours, preferably 16 hours and even up to 24 hours after the cleaning action.

  • Ants were collected in a plastic container manually from the insectary at least 1 hour before the initiation of the experiment. Treatment Method
  • test item was applied at recommended dose (1 ml) on the test surface in one half. Amount of test item applied were assessed based on the pre and post weight of the container.

Next day after about 16/24 hours of test item application, a total of 20 Nos of ants was released at the centre of the experimental area and allowed to acclimatize for 10 minutes. To test the samples without probiotics, the observation was made after 1 , 4 and 6 h after application of the product to the tile.

Abstract

La présente invention concerne une composition qui est utilisée pour nettoyer des surfaces tout en luttant contre les insectes. La composition peut être utilisée sur des surfaces dures dans des maisons telles que celles sur des ustensiles, des meubles, des sols, des murs, des toilettes et sur des surfaces molles telles que des vêtements, un rembourrage, des draps et des couvertures. L'utilisation de la composition sur de telles surfaces garantit un nettoyage durable et permet d'éviter que les insectes soient attirés vers de telles surfaces jusqu'à 24 heures après le nettoyage de la surface. Ceci a été réalisé par l'utilisation d'une composition de nettoyage comprenant une spore bactérienne de Bacillus, un constituant d'huile essentielle sélectionné et un tensioactif.
