Hi Kenny,
My experiance with ants was rather different to yours and I posted this last September but as it is relevant I will repost it here with apologies to those who read it previously:
I had a very embarrassing moment last night that will be with me for a day or two.
I was cooking my evening meal, baked jacket potato, in my oven and had just grated some cheese to top it with. As I had opened a new pack of cheese I needed some cling film to wrap it in. This is kept in a small cupboard alongside the oven but on opening it I found that I had visitors - ants.
Now in Portugal there are two types of ant, one is about 6 or 7 mm long and is quite a friendly type that will wander in one's place and nod his head or wave a leg as he passes by but most of the time he is outdoors. He is usually on his own unless he has come to take one of the cat's biscuits to feed the youngsters and then he will bring two mates to help carry the load, which is fine.
The other type of ant is less than 1 mm and is a different kettle of fish altogether. When he comes it is mob handed with several thousand of his mates and is most unwelcome and this was what I had been invaded with. Prepared for such an eventuality I have a very large aerosol of insect spray which not only clobbers the little blighters it prevents others from following after the initial attack.
Armed with my trusty weapon I went into battle and was spraying the invaders left right and centre and pulling shelves out at the same time to take better aim. I was definitely gaining the upper hand when I sprung the surprise attack (well it certainly was a surprise to me). The spray's propellant and oxygen had reached critical mass and was ignited my the oven. There was an explosion and a flash fire and suddenly I had a flame thrower in my hand which was rapidly discarded.
The upshot is, apart from some superficial burns, I now have no hair on my arm and legs, my eyebrows are practically none existant and my thining hair is even thiner and shorter. I will probably have to stay at home for a day or two until the hair has recovered somewhat.
I do not have any ants any longer though.
