Abstract
ABSTRACT OF THE DISCLOSURE
The composition comprises a mixture of a C1 to C5 alcohol, an attractant for flying insects which could be a sugar or sugar substitute or derivative containing syrup, fish oil, ammonium bicarbonate and/or yeast, and the balance comprising water. The method of killing flying insects comprises providing an ecnlosure having an inlet enabling penetration by flying insects, the enclosure including a compartment to contain the above defined composition and placing the enclosure in an environment where flying insects are present. Alternatively the composition may include yeast and a dry sugar containing substance such as dry molasses and dry honey, or ammonium carbonate to be diluted in water until ethyl alcohol is formed, before introducing the composition inside the enclosure. The composition has the advantage that it does not only attract insects, but due to its alcohol content it also kills them.

Description
:~3~ 3~:~
This invention relates to a composition which is useful for attracting .and killing flying insects. More particularly, the present invention is concerned with the destruction of flying insec-ts by attracting them in a medium where they are killed just abou-t ins-tantaneously>
Although insects have a definite role in the equilibrium of nature, some of them are really harmful to humans and, to say the leasc, rnost of them are plain noxious.
On the o-ther hand, the chemical indus-try has produced thousands of insecticides which can be used with a different degree of success in fighting crawling as well as flying insects. Recently, however, it has been found that chemical insecticides are harmful to humans and animals and are very detrimental -to the environment.
In my previous Canadian Patents 1,112,158 and 1,185,172 I have described insecticidal natural bait compositions which are both based on -the use of diatomaceous earth. In the first patent mentioned above the attractant is a sugar, while in the latter patent, the attractant is a yeas-t. It should be noted however that these insecticidal compositions are only useful in getting rid of crawling insects, such as cockroaches and tha-t they have no effect on flying insects.
Some attractants of flying insects are known in the prior art. E'or example, U.S. 3,160,556 discloses that dioctyl phthalates consti-tu-te fly baits when used in association with DDVP (0,0-dimethyl-2,2-dichlorovinyl phosphate). However, it should be remembered tha-t this is a chemical insecticide which possesses -the disadvantages mentioned above.
~3~'7~
~ .S. 3,7~8,318 discloses a me-thod oE attrac-ting yellow-jacket wasps by ~using pentyl pentanoate alone or in association Witll -triethyl citrate. This is of course another method involving one or more chemicals.
According to U.S. 4,581,845 insec-ts are a-ttracted inside an enclosure where they die by suffocation when in contact with an oleaginous substance. This is a complicated struc-ture which does not necessarily rely on a particular attractant and/or killing substance.
There is thereEore a need for a composition which is cheap to produce, is effective ln attracting flying insects and causes no harm to the environment.
It has now been Eound that a liquid composition containing an alcohol, an attractant for flying insects and wa-ter provides an interesting substance for use in attracting and killing flying insects.
Although any attractant known to attract flying insects can be used, the preferred agents, used alone or in combina-tion, include sugar containing syrups, such as grenadine or cherry syrups, fish emulsions, yeast, ammonium bicarbonate or the like.
Any alcohol which is liquid at room temperature, can be used in the composi-tion according to the invention, such as me-thyl, ethyl, n-propyl, isopropyl or pentyl alcohol, ethyl alcohol or isopropyl alcohol being preferred.
The amoun-ts of ingredients used in -the composition according to the invention are not critical and the exact quantities used will vary depending on cos-t, effectiveness of the composi-tion and the types of insects intended to be destroyed. For example, a sui-table insecticidal composition comprises about 5 to about 15 volume percent alcohol, about 5 ~3~
to about 20 volume percent at-tractant, and the balance comprises water. In practice, an excellent insecticidal composition could consist of about 75 volume percent fish emulsion, about 20 colume percent alcohol and the balance consists of wa-ter.
According to a preferred embodiment of the invention, it has been found useful to form the alcohol in situ. For example, the composition may consis-t of essentially dry ingredients which can be converted into alcohol and still containing a flying insect attractant.
The invention therefore also relates to a composition for use in attracting and killing flying insects inside an enclosure containing the composition and having means enabling the flying insects to penetrate therein. The composition comprises yeast and a substance selected from the group consisting of a dry sugar containing substance, and ammonium carbonate, the composi-tion to be diluted in water to allow ethyl alcohol to form therein before introducing it inside the enclosure and to develop flying insect attracting properties.
The preferred dry sugar containing substances include dry molasses sold under the trade mark Dry Flow Special 75, dry honey sold under the trade mark Dry Flow Honey Buds 315-S and the derivative sold under the trade mark MALTONINE DRY-ME. It has been found that these substances are easy to manipulate, they are not costly and furthermore they constitute a good flying insec-t attractant once admixed with yeast and water.
The composition preferably contains about 5 to lS
parts yeas-t per part of dry sugar con-taining subs-tance, more preferably 8 parts yeast, per part of dry sugar containing subs-tance.
The method of use ineludes introducing the composition in about 50 to 100 parts water, preferably about 80 parts, allowing the liquid mixture to fermen-t at about 110F for about two days, holding it a-t room temperature for about four days, after which the composition is ready to be introduced into a flying insect trap.
Parts are given by volume.
The invention will now be illustrated by means of the following examples.
The following composition was produced:
300 ml ethyl alcohol 4 1 water 300 ml of a solution containing yeast and ammonium bicarbonate.
~he composition was introdueed in a flying inseet trap. Flying insec-ts penetrated in the trap whieh was elosed.
Ag-ter 24 hours all the insects had been killed.
The same results were obtained with the Eollowing composition:
300 ml e-thyl aleohol 4 1 water 300 ml cherry syrup.
The same results were obtained with the following eomposi-tion:
~3~
300 ml ethyl alcohol 4 1 wa-ter 300 ml fish emulsion.
A mixture was prepared containing 8 parts dry yeast and 1 part dry molasses sold under the -trade mark DRY FLOW
SPECIAL 75. The mi~-ture was introduced into 80 parts water and was allowed to stand at about 110F for two days. This was followed by room temperature standing for four days. The mix-ture can then be preserved indefinitely. The mixture was introduced inside a flying insect trap. A variety of ~lies and mos~uitoes were attracted inside the trap including domestic flies, and flies commonly found on cows, horses, fruits and toilets. A~ter twenty-four hours all insects were dead.
The same results we obtained by substituting dry honey (DRY FLO~ HONEY 315-S) for the dry molasses of example ~.
The same results were obtained by substituting MALTONINE DRY-ME for the dry molasses of example 4.
The same results were obtained by substituting ammonium carbonate for the dry molasses of example ~, except that because of its very bad odor i-t could no-t be used in a domestic environment.

SUPPLEMENTARY DISCLOSURE
It has now been found that a simple mixture of yeast including wine yeast with a sugar containing sub-stance such as molasses, honey, or malt with or without ammonium carbonate produces even better results than the compositions defined in the principal disclosure.
For example, using about 5 to about 35 volume percent yeast, the balance consisting of molasses, honey or malt extract, excellent results having been obtained with the same type of enclosure as in the principal disclosure.
