Home-Made Pesticides

Thursday, February 2nd, 2012

if you are one of the growing number of people worldwide that thinks that we should start using fewer chemicals on our planet, then you have probably wondered about home-made pesticides. Once you have had a lung full of ant spray or cockroach spray, you know that it would be a good idea if you could use something less ghastly.

The problem is that we have come to depend on a spray of this to destroy ants, a spray of that to kill cockroaches and another spray for silverfish or whatever. This is all a big con. You do not need three or four sprays to kill or deter all the insects that you are concerned about.

In fact, many sprays contain the old-fashioned pesticides, but they are packaged so as to make you pay a lot more for them.

Boric acid can be used to kill all insects that have mandibles and scavenge. If you want to eradicate ants, mix it with water and sugar. It will be taken back to the nest, if you do not make the mixture so strong that it kills the ants before they can get home. Boric acid will also poison cockroaches. Mix it with flour or pour it in liquid form on bread.

You can kill greenfly or aphids quite effortlessly, by spraying them with your used washing-up water. Soapy water is all you require to kill these insects.

The Colorado potato beetle is a pest in some countries. You can kill or discourage the Colorado potato beetle with a spray made from soaking cedar wood chips in water. This will make a tea-coloured fluid. It is a powerful pesticide and an antibiotic too. Spray it onto the foliage.

You can also use a foliage spray made from tansy. The method is to dry the tansy and then grind it up – as finely as you can be bothered to. Use a pestle and mortar and then mix it with water. The finer you ground the tansy, the fewer blockages you will suffer in your spray gun.

Cutworms can be defeated by mixing pineapple weed with water and spraying on affected areas. Sagebrush and water will have the same effect, but you may need to boil the mixture to extract the essential oils.. If you do not have these plants where you live, you can mix molasses with bran or sawdust and spread that on your plants just before dusk.

The tomato hornworm causes a great deal of damage to tomatoes where they exist. This technique of destroying them is not a pesticide as such, but it is very effective. Spread cornflour around your tomato plants, the hornworms will feed on this too, but they cannot digest it. It will soak up their digestive fluids , expand, and blow them up. This technique can be used on cockroaches too.

A spoonful of canola oil and a drop or two washing-up liquid in a spray gun will exterminate most soft bodied grubs

Diatomaceous earth is a good barrier to all insects and is one of the few ways of clearing out bed bugs too.

How To Get Rid Of Carpenter Ants

Tuesday, January 24th, 2012

There are over 1,000 species of carpenter ants. Most of them are large, between a quarter of an inch and an inch long, and black, although there are red ones too. There are even a few species in South East Asia which will explode if threatened, ejecting a sticky substance out through their heads which immobilizes the attackers. The exploding carpenter ant dies.

Carpenter ants are thought to do a lot of damage to timber, as they gnaw their way up the middle through its length. However, this is a popular myth, unlike termites, carpenters do not eat wood, they chew their way through it to get somewhere. They spit the gnawed wood out. This is called frass and it can often be seen in heaps like sawdust. It is a good sign that carpenters are active in or around your home.

Carpenter ants like to travel through the length of damp or rotten dead timber in much the same manner as termites do although they do not consume the timber. Carpenters feed on dead insects, dead animals and honeydew from aphids and scale insects outside the home, but if they come inside your home they will be looking for dropped or uncovered food, especially anything sweet and sugary. Therefore, hygiene is an important factor in clearing carpenters out of your home.

These ants will walk up to a hundred yards while looking for food, but they like to be close a recurring supply of food. A characteristic of carpenter ant colonies is that they may construct satellite nests away from their main colony. This is often why they go into a home.

If they regularly find spilled food in the kitchen, they may make a nest in the wall to take advantage of it, particularly if the window or door frame is a bit decayed. Inside the home, they will probably nest in a cavity wall, outside the home they prefer to construct nests in decaying tree stumps.

It is no good spraying carpenter ants with insecticide if you want to get rid of them – especially if you kill large numbers of them. This may sound odd, but the reason is that the nest will miss these workers and so the queen will increase her production of eggs to counteract it. If she over compensates, you are in a worse situation that you were before spraying.

The only way to destroy a nest of carpenter ants is to destroy the queen and the entire colony with poison. This is not difficult although it does take a bit of investigative work. Carpenters are most active between dusk and midnight, so put out honey on glass or sticky tape where they are active and follow them when they take it home.

Do not forget, they may have several nests in their colony. If you have to have light, wrap red cellophane over a normal torch, because ants can not see red light. When you have found their nests, put poison down outside each nest as indicated on the label. Do this for several days in a row until you do not see anymore carpenter ants. If you are still getting them, you have missed a nest.

Depending on the materials there made of greenhouses can either be permanent or temporal structures which are not fixed on any structure and have mobility.

Often temporal structures are made of light materials such as aluminum to ease their mobility. Other made of such materials as wood are permanently fixed on sides of other structures. On the other hand permanent green houses which are fixed to the sides of other structures are often made of wood.

Dome green houses are very sturdy. This is a style of green houses which is usually a semi-circle set on the ground and is the best choice of a green house in areas where there is a lot of snow falls. Its shape makes it look feeble but it’s actually the strongest kind that can be made.
