How can spiders be deadly in chimneys? These are not some exotic species that hitched a lift in a box of bananas. They are common spiders, found all over the country. The cobweb in the picture was blocking a chimney. The odd colour is brick dust drawn up the chimney from below during refurbishment work. Cobweb can act like a filter, catching dust and blocking the chimney.
The video below shows a mass of cobwebs which had completely blocked the chimney above this wood burning stove. Blocked chimneys can be dangerous!
Guild of Master Chimney Sweeps chairman Lawson Wight said, “The video shows a large mass of cobweb which built up over the summer months, blocking the chimney. This can be very dangerous as it can let poisonous gasses in to the property.”
Lawson added: “Chimneys can be a great environment for spiders. We sometimes hear customers saying they don’t think the chimney needs sweeping because they didn’t use it much last year. Cobwebs are just another good reason to call your local professional sweep.”
