Grub and slug repellant?

From a Facebook post, pay special attention to #4.

FACTS OF THE DAY ....
Cucumbers... I didn't know this... and to think all these years I've only been making salads with the cucumbers...  
1.  Cucumbers contain most of the vitamins you need every day, just one cucumber contains Vitamin B1, Vitamin B2, Vitamin B3, Vitamin B5, Vitamin B6, Folic Acid, Vitamin C, Calcium, Iron, Magnesium, Phosphorus, Potassium and Zinc.
2. Feeling tired in the afternoon, put down the caffeinated soda and pick up a  cucumber. Cucumbers are a good source of B vitamins and Carbohydrates that can provide that quick pick-me-up that can last for hours.
3. Tired of your bathroom mirror fogging up after a shower? Try rubbing a cucumber slice along the mirror, it will eliminate the fog and provide a soothing, spa-like fragrance.
4. Are grubs and slugs ruining your planting beds? Place a few slices in a small pie tin and your garden will be free of pests all season long. The chemicals in the cucumber react with the aluminum to give off a scent undetectable to humans but drive garden pests crazy and make them flee the area.    

Plus many more cucumber uses. Full post somewhere on All Pagan Loot's feed.

What do ya'll think? Would it drive away our pollinators too?

I suspect it would do absolutely nothing even if it were to magically make a scent that things didn't like aluminium is extremely reactive and will very quickly form an oxidised layer that will stop any further reaction.

When I'm looking at sites like that I tend to find the easiest thing to prove/disprove and whether that stacks up decides how I treat the rest of the site. so taking point 1. Cucumber does contain most of those things (no folic acid just folates) however as one would expect for a product that is 96% water it doesn't contain much of any of them. (1% of the RDI or less per 50g) so the wording is implying much more than the reality, and then reading point 2. they are a terrible source of B vitamins that one 300g (10.5oz) cucumber can supply you with a whopping 0.3mg of B3 which is 2% of your daily needs that's not going to perk anything up, equally they are a very poor source of carbohydrate (obviously that's why dieters love them) that same 300g cucumber will give you 10.8g of carbohydrate of which half is sugar so if you find a teaspoon of sugar is a pick me up maybe point 2 is correct.

So since point 2 is technically correct but misleadingly written and point 3 is plain wrong I will take anything else the site says with a large pinch of salt, possibly on a cucumber salad.

Joylynn, Thanks for sharing!

I love getting helpful hints.

Some other ways to repel slugs is to try spent coffee grounds.

If that doesn't work try pouring some beer in a dish.

This one is good for slugs and snails: place orange peels on the soil. When the slugs or snails are attracted to the peels, the peels can be removed with the slugs and snails. Maybe put them in the compost.
