I purchased this product after an invasion of giant house spiders this year. The pest control officer said that there must have been a nest in the house. They were very large and would appear all over the place, including several crawling over my desk! Not very pleasant. I am hoping this product will do the trick. I will use it again from next August to see if I can stop the annual autumn invasion, but it has never been as bad as it was this year.
UPDATE ON THIS PRODUCT:
It's now October 11 and I started to use the Spider X spray several weeks ago when the giant beasties started coming into the house. Last year was terrible, absolutely HUGE spiders invading every day. Once I had sprayed liberally, I didn't see any spiders for a couple of days, then started to find them...DEAD. This spray might not keep them out completely, but it does kill the ones who come in. Also, there have been far less of them this year. As well as being a deterrent, it must also have some insecticide for spiders in it. This morning on having a good hoover around, we found six more large dead ones. I am going to buy this product again, as I think it's worth the money. I used to hoover up spiders with the SpiderVac, which is £9.99. But I think that once out in the garden, the crafty little critturs just used to come back into the house! Now I am going to spend the money on the spray instead.
