False widow spiders

[mithrandir]

Just wondered if anyone on here knows of a good way of getting rid of the false widow spider.

A lady at work has an infestation of them in her shed, and as the bites can be dangerous to people with heart conditions ( which she has ), she wanted to get rid of them. The local council do not deal with them and pest control people are expensive, she wondered if there was any poison spray she could use to kill them, most insect sprays are not effective of spiders. The pest control officer has suggested she tread on them!!!

So any good ideas of a reliable toxin for false widow spiders?

I think DOFF do a Crawling Insect Powder, that works for me! Not good to breathe in though.

If not, is it an old shed?

"Aerosol can ignited?"

You didn't get that from me though.
