Hilary, keep the door closed? Alternatively, have you tried a 2nd internal door or translucent plastic strips? Whilst they do reduce visibility for FLT drivers they do form a barrier for the feathered rats. Also, spiked strips along all the horizontal roof supports such as are found on external window sills of many buildings. Failing that, being Friday, what about signs at the doors?

Hilary, have the pigeons had an induction? Seriously, David's advice is similar to what I would have said. Find out where they reside and put spikes to deter them from roosting. You can also engage someone with a bird of prey to scare them off, however you may find they return at some point.

Stuffed Owls - try them http://www.pigeoncontrol...rching-plastic-owls.html

Have you considered Pie ? I think you will find you are not supposed to exterminate wild birds during the nesting season or when they have young ? so too late this year I would guess. We used to have a sea gull problem in a previous employment, they would attack employees. We tried the bird of pray thing, But they only went for a while and it was expensive. We also tried plastic birds of pray at strategic locations on the building etc. About two weeks after installation an employee took a photo of a seagull stood on the head of the plastic bird of pray - we gave up. Where's tiddles ?

Are pigeons classed as vermin? The dove is protected. http://pigeoncontrolreso...control-and-the-law.html

The pigeons will need somewhere to rest, usually under eaves. Taking pot-shots at them won’t shift them but might end up injuring someone. The best thing to do is to put nets over the spaces where they like to rest. Nowhere for them to rest, they’ll move on.

Feral pigeons will nest and rest on every single horizontal ledge they can get their bottoms on. (like any and all steel girders in a factory) You'll need a lot of nets and spikes. Quite frankly, like Tesco's and the super markets.. you may be stuck with them. The best think you can do is clear up and food source and set about clearing up the mess after them. True about taking shots at them. Not the best plan but it was said with my tongue-in-cheek and I didn't think anyone would think I was serious about using a weapon in a factory situation.

Based on personal experience of 'discouraging' pigeons from railway depot building, I would suggest you consider the following. 1. Block off all openings where possible 2. If you need windows that open - fit them with small size grillages to prevent entry 3. Cover all flat [roosting' surfaces with anti-pigeon spikes 4. Depending on the roof structure [i.e., if its a lattice girder type structure] - fit a complete horizontal netting screen below the girders, so pigeons have nothing to fly up on to 5. Fit a secondary screen behind roller shutter door to deter pigeons 6. Keep plugging away with the exterminators. 7. Remove any food sources - including uneaten staff sandwiches etc Good Luck - you'll need it

Alan Haynes' response at #16 contains plenty of good practical advice. Though this thread is about pigeons inside buildings, it might be worth mentioning that many buildings and other structures such as railway bridges, especially in towns and cities, have anti-pigeon spikes and/or nets to keep pigeons off their exteriors. The benefits of such spikes and nets include eliminating or minimising the need for routine cleaning of pigeon droppings from such structures and all the costs and risks involved. The nets used nowadays tend to be very fine and transparent so their presence is not readily apparent from a casual glance. Another reason for trying to deal with pigeons inside industrial premises is the possibility that some employees might endanger themselves by climbing to the roost areas and trying to catch a few for cooking and eating. Though this scenario might seem far fetched to some, it was the basis of a civil compensation case Uddin v Associated Portland Cement Manufacturers Ltd in 1965. Mr Uddin had claimed compensation after suffering serious injury through contact with moving machinery while trying to catch a pigeon in an overhead area. Though the company was adjudged to be at fault for not guarding the machinery involved, the amount of Mr Uddin's compensation was reduced by 80% because he should have realised that his actions in going where he did were foolhardy. The detailed report of the case contains some humour in that the judge made a wry passing comment that Mr Uddin's "actions were not actuated by benevolence towards the pigeon". Come to think of it, if any forum users have experienced eating pigeon (or rather cooked pigeon meat to be exact), can they say if they found it tasty or otherwise? If it's okay, perhaps there's a niche market for capturing pigeons and selling them for consumption! Also, though pigeons are well known for carrying nasty diseases, I guess that their meat, like that of chickens, is safe to eat if properly prepared and cooked. Furthermore, if one or more celebrity chefs were able and willing to extol cooking pigeon, perhaps it could become the latest culinary fashion! :-)
