garlic sprays

after watching someone making a garlic spray on the TV and the benefits of using garlic spray I thought I mite try that should I mix my own or buy well if I buy enough garlic spray a bottle costing around £15 quid would make 5lts of spray ?

so do I bite the bullet and make my own because its said garlic spray will  control the slug population and hopefully caterpillars and its organic


so wats your opinion on using garlic spray does it work ? how long does it last before one needs to respray?

I am currently trying a spray that in theory will resist slugs, snails, catterpillars and kills the likes of blackfly.
I can say after watching a slug last night crawl upto a sprout leaf, then what looked like about to take bite then turn into a ball (I suspect in pain) and promtly crawl away again I would say on slugs it worked.
So the recipe.
2 orange peels
1 garilc clove
good sprinkling of black pepper
2 really hot chillies (I use chocolate trinidad scorpion)
chop up and put in a pan (windows open) and bring to boil and simmer for about 20 mins. Leave overnight to steep.
Put into blender and whizz up. This will make about 500ml of puree.
Now when your ready add half to a jug and then top up to 1 litre and add 1 Tspoon of liquid soap.
I then give a good stir and pass it through cloth into the spray bottle.
It seems to last a while even when it rains.

There is some evidence that garic spray is toxic to pollinators like bees.  Unfortunately organic doesn't mean safe.

it seems that garlic spray will be worth trying I'm going to try your recipe Aidy because it seems to be working for you and it seems a better  alternative than  using chemical spray that is quite effective but quite costly that i use

going to copy your recipe in my garden log will let you know if it works for me many thanks for your all your replies

As I say mine is used mainly on brassica which until it goes to seed wont affect the bees. One word of warning tho which I forgot to add, if using super hot chillies wear some gloves for both prepping the chillies and also spraying the veg.
