JPH05255007A - Natural or equivalent nontoxic formulation for exterminating ant, termite or analogous insect - Google Patents

Abstract

PURPOSE: To obtain the subject nontoxic formulation containing natural or equivalent borneol, isoborneol, eucalyptus oil, etc., and preferably further isopropyl alcohol, a lemon oil, etc., as an action-improving substance or smell- correcting substance. CONSTITUTION: This natural or equivalent nontoxic formulation for exterminating ants, termites and analogous insects contains borneol, isoborneol, eucalyptus oil, etc., Caryophylli flos oil, eugenol or indole, and preferably further isopropyl alcohol, lemon oil, Seville orange oil, citral, citronellal or an etheric citrous oil. The borneol or isoborneol is preferably used as an especially active substance in a concentration of about 0.5-60%. The formulation comprises nontoxic natural substances, and does not cause an environmental problem, even when used.

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a natural or natural-like nontoxic agent for controlling ants, termites and related insects.

[0002]

BACKGROUND OF THE INVENTION Known and marketed ant agents today are toxic and health-impairing substances.

In particular, the following have been used: 1. Bromphos contact-and feeding poisoning insecticide O- (4- bromo-).
2,5-dichlorophenyl) -O, O-dimethyl trifluorophosphate trivial name 2. Phoxim contact- and feeding poisoning insecticide O, O-diethyl-O
The conventional name for-(α-cyanobenzylideneamino) -fuionophosphate 3. The insecticide ethylamino- (E) -O- (2-isopropoxycarbonyl-1-), which acts as a propetamphos cholinesterase inhibitor. Methylvinyl) -O-methyl-fluorophosphate trivial name Although these insecticides have a good action against insects such as ants, they are not biologically safe. Because there are unpleasant side effects due to its toxicity when using it in the house or in the garden (contamination of soil and groundwater, danger to children and livestock).

Lindan, Dichlorvos, Propojour
oxur) or trichlorfon (Trichlorfo)
The conventional chlorine-containing agents which contain n) and are used in powder form or in aqueous solution are of limited use since they are aqueous solutions and can therefore be absorbed by plants.

Further, toxicity to fish and fish-producing animals can be mentioned.

Another point is the danger to bees (1
(See Bee Protection Ordinance of December 19, 972).

[0007]

DISCLOSURE OF THE INVENTION The present invention relates to the following natural or natural product-like substances which are not toxic but have a eradicating action against ants.

[0008]

It has been found, and unexpectedly, that the naturally occurring substances borneol and isoborneol have a strong exterminating action against all species of ants, and the present invention is based on this. Is based.

This action is based on the inhibition of ant's instinctive sense of direction. Loses the ability to return home. If the nest and entrance are sprayed directly with this drug, the ants will escape from the nest and will no longer return.

According to the invention, the main active substances borneol and isoborneol are supplemented with the following additives: natural or natural lemon extract (ether oil from lemon peel), orange oil, remetta oil, grapefruit oil. Or other citrus oils such as mandarin oil, peppermint oil, menthol, citronella oil, clove oil, eucalyptus oil or a single component thereof and isopropyl alcohol and related alcohols. These additives enhance the aiding action and give the formulation a pleasant odor for humans.

Borneol and isoborneol (1,7,7-trimethylbicyclo-1,2,2-) heptanol are used in the perfumery industry to perfume mannen wax, lavender and fir scents. It is also used as an “indoor fragrance” for Buddhist culture.

It is nutmeg, carrot, citrus fruit,
Cowberry, strawberry, cinnamon, ginger, peppermint, pepper, thyme, hop oil, apple brandy, cacao,
It is known as a natural component of ham, mayonnaise, coriander, gin, fermented soybean hydrolyzate and valerian oil.

The use of colloidal silicic acid or derivatives thereof natural products as fillers and the use of substances which tend to agglomerate (eg salts, seasoning mixtures etc.) as flow aids are known and legally permitted. ..

No use is known for ant auxiliaries. Silicic acid allows a wide distribution of natural and natural-equivalent substances. Therefore, the ants are exterminated better.

Silicic acid is not an aqueous solution. Therefore, it was not possible to predict that a good suspension would be achieved after a simple stirring of the mixture of the substances mentioned above and silicic acid in water, and thus could be applied to ants as irrigant and dusting agent. Borneol, isoborneol, menthol and silicic acid themselves surface-float immediately in water.

[0016]

Examples Example 1 Concentrated ant auxiliaries for water suspensions Silicic acid 5% Mint oil (6% menthol) 1% Borneol 80% Isoborneol 14% 100% Example 2 Exterminators for direct spraying and liquid irrigation Agent Silicic acid 5% Lemon essence 3% Wood flour or similar powdered cellulosic material 30% Borneol 32% Isoborneol 30% 100% Example 3 Ali repellent spray Wood flour or similar powdered cellulosic material 55% Silicic acid 5% Lemon essence 3% Borneol / isoborneol (75/15% mixture) 35% Isopropyl alcohol 2% 100% Grind the above ingredients vigorously. This gives a very homogeneous mixture.

By finely grinding the above-mentioned natural or water-insoluble substance equivalent to the natural product, a good distribution in water is achieved, and therefore a liquid irrigant can be produced.

Furthermore, the above-mentioned powder mixture is excellent in that it can be used directly as a dusting agent.

Testing for Efficacy The above-mentioned ant control sprays were tested against the following types of ants in homes and gardens: Tetramorium.
caespitum; Raseameise Camponotus sp
ec. ; Rossameisen) Lasius niger; Sc
hwarzgraueWegameise Lasius fuliginos
nosus; Glanzendschwarze Ho
lazameise Lasius umbrat
us; Gelbbraune Holzameise) Lasiu a brunne
us; Schwarzbraune Holzamei
se) In all cases, all ants lost their orientation, regardless of species, immediately after spraying the ant pesticides down the road. Direct treatment of the nest caused the same confusion and fled the nest. Animals lose their sense of direction. As is well known, ants walk along the scent trail (= ant trail) The advantages of the agents according to the invention for producing ant auxiliaries are as follows: -relatively non-toxic natural production Is a substance, its use does not pose an environmental problem.
