A former stuntman has warned would-be vandals they face being fired at with a catapult loaded with chicken manure.
The catapult has not been used since 1974
Former stuntman Joe Weston-Webb, 70, said his offices in Kegworth, Notts, have been attacked by arsonists and he was fighting back with the weaponry.
Mr Weston Webb said: "There's no way anyone will get caught...so I thought I would set up my own defence."
A police spokesman said they would give "practical security advice" but warned against using "unreasonable force".
Mr Weston-Webb, who supplies flooring to hit BBC show Strictly Come Dancing, said he will also use a cannon, which once shot his wife Mary across the River Avon in a circus show, to fire a railway sleeper at intruders.
"I have put up a sign warning anyone who enters the property that they could get hit with a railway sleeper or chicken poo.
"I have got all this old kit and I am going to put it to some use and stop it rather than letting it rot in a field."
Mr Weston-Webb said the arsonists had caused £2,000 of damage to his offices.
He said the 30ft (9m) catapult would be dragged into location with a tractor and loaded with chicken manure.
"It will fire and cover the person with the stuff - and we will be able to smell who it is," he explained.
The former stuntman is installing 32 CCTV cameras
Mr Weston-Webb said the device will not injure anyone because "a bag of chicken poo isn't going to do much".
The businessman, who runs Grumpy Joe's Flooring Sales, is also installing 32 CCTV cameras.
Insp Jeff Haywood from Nottinghamshire Police, said: "A crime prevention officer will be making contact with the complainant to offer some practical security advice.
"The officer will give tips around conventional security techniques, such as alarms, lighting and locks, and also around the use of reasonable force.
"The law allows homeowners to protect themselves and their property with reasonable force if they are under threat from an intruder.
"However, the reasonable force must be proportionate to the threat. The setting up of booby traps is outside the scope of the law and is something Nottinghamshire Police would advise against."
