Homemade Organic Insect Repellents – Pesticides

Homemade Organic Insect Repellents – Pesticides

Posted on 20. Aug, 2010 by in odd stuff, product

I’m all for home made Insect repellents and pesticides, stuff you can make in your kitchen for three reasons

1. It’s cheap – virtually free
2. It’s environmentally friendly
3. It’s healthy for the plants, veg and ultimately us

All our pesticides, mainly, fall into the area of sprays that are made up of water and basically strong smelling odours or strong tastes from plants and their produce that the offending insects/pests find repellent.

The basic premise is to steep the organic material in water to make an infusion and strain through muslin/cheesecloth/nylon mesh alternatively an old tea towel or a pair of tights serves the purpose just as well. Put the infusion in a recycled hand pump spray bottle. And away you go.

Might seem a good idea to use boiling water to extract the ‘flavour’… TO BE AVOIDED as cooking tends to impair the active ingredients.

The biggest garden villain is Aphids : Best way my grandad told me to deal with these is to wash off as much of the aphids as you can … and let the plant dry. Them make a simple Soap water spray with 3 tablespoons (tbsp) of washing up liquid in a bucket of water (about a gallon). Apply to the plant especially under the leaves… wait a couple of hours and do again. You can spot aphid infestation as the green leaves start to curl and wither … repeat until no more aphids are seen … this might take a few days. Also effective on spidermites, thrips, mealybugs, and whiteflies

For serious Whiteflies, spidermites and caterpillars problems: Try liquidising 3-4 hot pepper/cayennes or tobacco sauce, a few cloves of garlic and water… let it stand … strain into the bucket to dilute further and away you spray. This Hot pepper-garlic spray also keeps rabbits away.

You can also keep Cats off you prize plants by treating them with a coffee spray which also acts as a fertilizer for the plants

Mildew : Into the chemistry set here, Gallon bucket of water again , 3tbsp of Baking Soda, 1tbsp of Bleach, 1tbsp of washing up liquid … Remove the worse affected leaves, we can’t raise the dead and spray top and bottom … Plant and Bleach are not good together so don’t overdo the bleach is you want to increase the concentration.

Ants : Mix caster sugar and Borax, also known as sodium borate in equal parts… better than any expensive shop bought product.. the worker ants takes the sugar/borax back to feed the queen and the borax kills the queen … works indoors as well as out… although are they really a pest, outdoors.

Slugs: Many slug species play an important ecosystem role by eating dead leaves, fungus, and decaying vegetable material. If a serious problem … bury a jam jar in the soil.. open end level with the soil … and put some beer in it … they go in for the beer and can’t get out.

As a totally Eco-friendly option try

Companion herbs/plants: One sustainable garden practice would be to plant angelica or morning glory to attract ladybirds/ladybugs (Coccinellids) to your garden or I believe you can buy them, 100 in a reasonable sized garden will do. Most Coccinellids are beneficial to gardens, as they feed on aphids, scale insects, mealybugs, and mites throughout the winter.

There are other sprays, potions and liquids you can make… although the ones above are probably the most common… Try them and save yourselves some money.

Personally the ladybird option is the one I would urge you to strive for as it’s nature – wildlife in miniature and if you have kids it’s a wonderful place to get them involved in the environment around them.

Anyway… whatever you do … stay away from chemicals and happy bug hunting
