Description
METHOD FOR REMOVING INSECTS FROM THE EXPOSED SURFACE OF A
BODY OF WATER
FIELD OF THE INVENTION
The invention pertains to the field of insect control, more particularly the control of all species of wasps, or any member of the aculeate family Vespidae.
BACKGROUND TO THE INVENTION
All species of wasps can have serious negative effects on the quality of human life when they are gathered together in large numbers in a small area.
When found in a recreational area, such as a garden, these pests can be a source of annoyance purely due to their presence and the fact that they are capable of injecting poison. A sting from a wasp is poisonous because of the venom injected, and as a result, it can cause severe allergic reactions. Young children and the elderly are at higher risk.
When a wasp stings a person, the muscles that surround the wasp's venom sac inject venom into the body. Once the venom is injected, the person will experience a severe stinging feeling, followed by swelling, redness and itching.
After that, the person may notice a large red area on the skin where he or she was stung. In rare cases, a bacterial skin infection can also occur. In some cases, people who are allergic to the stings can suffer severe medical problems and death. Around 100 people die every year from wasp stings.
Some symptoms of an allergic reaction include, swelling of the throat, nausea, vomiting, low blood pressure, a rash all over the body and faintness. If any of these symptoms occur, the person should receive immediate medical attention.
When a wasp stings someone who isn't allergic to its venom, the effect of the sting is usually minor. However, when a person receives multiple wasps stings, kidney failure, muscle breakdown and other problems can occur. Major problems can also occur in people who are not allergic to wasp stings, depending on where they are stung. If someone is stung by a wasp in the mouth or throat, swelling can occur that can obstruct the airway and make it difficult to breathe.
In addition to where a person is stung, several other factors determine how severely the sting will affect the person, such as how many times the person is stung.
Current effective methods of controlling wasps involve the use of pesticides which can be highly dangerous to both humans and animals.
Current methods that do not use pesticides are not effective in providing any control.
There is a real need to provide an effective method of controlling wasps which is both safe in the environment and also non-toxic to humans, animals and fish.
SUMMARY OF THE INVENTION
According to the invention there is provided a method for removing insects from the exposed surface of an open body of water, without the application of a pesticide, the method including the step of adding a surfactant to said water, thereby to cause insects alighting on said surface to drown in the body of water.
By use of this method, the insects are either repelled by the surfactant, or are trapped on the water surface, and therefore are drowned.
The present invention provides a method of controlling or eradicating insects such as wasps from swimming pools, and indeed any outdoor areas to which they may be attracted. The method does not require the use of any pesticides which are nearly always highly toxic to humans and also bad for the environment. The method of invention is environmentally friendly and totally safe to humans, animals and fish.
The method is especially applicable to insects which are members of the order Hymenoptera, most especially from the aculeate family Vespidae (wasps).
The biggest attraction to wasps is water as it is the essential raw material required to build / expand their nests. Wasps need water and lots of it so any recreational area with a swimming pool, pond or water feature of any description will attract large numbers of wasps in the summer. This large presence of wasps will always prevent the use and enjoyment of the swimming pool and recreational areas. The method used by wasps to collect water involves landing and floating on the surface of the water. This is possible because of their relative light weight and the surface tension properties of the water. Wasps cause the elastic surface of the water to bend but not break under their weight. Before landing wasps will test the surface tension of water by touching it lightly while hovering over it.
The present invention provides a method to control wasps which involves treating the water by introducing a surfactant or a combination of surfactants, dispensed either in liquid, powder, tablet or raw natural bio form into the water in order to reduce the surface tension between the two mediums, air and water.
After the introduction of the correct quantity and type of surfactant, wasps will still be attracted to the treated water but they will be prevented from collecting the water due to the now insufficient surface tension. Some will then simply fly away and find another source of water but most will still try to land on the surface only to then be trapped and drowned in the treated water.
We have found that after just a few days of treating the water, a previously infested area will be almost completely free of wasps.
The method preferably further comprising subsequently circulating water from said body of water through a filter to remove insect bodies therefrom.
The body of water is, for example, a swimming pool, wherein the body of water may comprise a chlorine-containing compound, such as sodium hypochiorite. In this event, the surfactant is preferably substantially inert to the chlorine-containing compound.
The surfactant may be in the form of tablets, liquid or powder composed of a surfactant or a combination of surfactants. In any event, the surfactant is ideally non-toxic to humans. A low-foaming surfactant is preferred.
The surfactant may be selected from anionic, nonionic, cationic, amphoteric and natural bio-surfactants. Anionic surfactants are particularly effective at reducing the surface tension by the amount required. However, they react in water with the positively charged water hardness ions (calcium and magnesium), which leads to partial deactivation. The more calcium and magnesium molecules in the water, the more anionic surfactants suffer from deactivation. Conversely rionionic surfactants do not have an electrical charge, which makes them resistant to water hard ness deactivation. A combination of anionic and nonionic surfactants would be most effective in treating water in countries, such as southern Mediterranean countries, where the water is generally much harder.
Furthermore, as the invention pertains to treating the surface of the water rather than the entire body of water, preference will be given to surfactants capable of forming a molecular monolayer across the entire surface of the body of water to be treated. Surfactant molecules often organize themselves into 3-dimensional spheres called micelles, which have, foe example, a hydrocarbon core and sulphate groups around the outer surface. However, some surfactants can also form other structures. Rather than forming a sphere, some surfactants can coat the surface of the water to form a layer one molecule thick, a molecular monolayer. It is these surfactants which are therefore most preferred.
Preferred anionic surfactants may be selected from carboxylates, sulphonates, petroleum suiphonates, alkylbenzenesulphonates, naphthalenesulphonates, olefin sulphonates, alkyl sulphates, sulphates, sulphated natural oils & fats, suiphated esters, sulphated alkanolamides, alkylphenols, ethoxylated and suiphated compounds.
Preferred nonionic surfactants may be selected from thoxylated aliphatic alcohol, polyoxyethylene surfactants, carboxylic esters, polyethylene glycol esters, anhydrosorbitol ester and its ethoxylated derivatives, glycol esters of fatty acids, carboxylic amides, monoalkanolamine condensates, and polyoxyethylene fatty acid amides.
Preferred cationic surfactants may be selected from quaternary ammonium salts, amines with amide linkages, polyoxyethylene alkyl and alicyclic amines, N,N,N',N' tetrakis substituted ethylenediamines, and 2-alkyl 1-hydroxethyl 2-imidazolines.
Preferred amphoteric surfactants may be selected from N-coco 3-aminopropionic acid! sodium salt, N-tallow 3 -iminodipropionate, disodium salt N-carboxymethyl N dimethyl N-9 octadecenyl ammonium hydroxide, and N-cocoamidethyl N hydroxyethylglycine, sodium salt.
Preferred natural bio-surfactants may be selected from soapnuts, soapnut powder, soapnut liquid, palm oil, coconut oil or any other natural substance possessing surfactant qualities.
Most preferably, the surfactant is derived from non-petrochemical sources and is, for example, saponin, which may be derived from soap nuts. We have found that the best natural surfactant is the plant-based surfactant extracted from fruit pericarps of Sapindus mukorossi, liquid soap nut detergent. The mass of soap nut liquid required in I litre of water to reduce the surface tension by the required amount is comparable to the mass of sodium dodecylsulfate solution required to achieve the same effect. The advantages of soap nuts compared to manufactured surfactants are clear. Soap nuts are completely natural, totally biodegradable and harmless to humans and animals. Furthermore, they have extremely low foaming qualities so, unlike petroleum based surfactants or other natural oil based surfactants they leave no greasy residue. They are a completely green' product. However, depending on different conditions such as the hardness of the water to be treated and the method of application, it may not always be possible to use a completely green bio surfactant.
The surfactant is preferably added at an amount of between I mg and 5 mg per litre of water.
The surfactant may be added to the body of water by spraying or pouring a solution thereof onto the exposed surface. Alternatively, especially where the body of water is a swimming pool, besides spraying or pouring, the surfactant may also or alternatively be added to water in the circulation system. In one possible embodiment, where the body of water is a swimming pool having a chorine-containing compound in the water, the surfactant may be added together with the chlorine-containing compound. To this end, the invention may provide a composition for adding to the water of a swimming pool, the composition comprising a mixture of suitable quantities of the surfactant and a chlorine-containing compound.
