FOUL OF THE LAW Cleankill Pest Control is warning site and building managers to pay particular attention to the netting on their buildings, especially if building contractors have been on site.

The Cleankill team is receiving an increasing number of calls to premises where birds have become trapped after netting was removed and incorrectly re-installed by building contractors.

Paul Bates, Cleankill’s Managing Director, explained: “Birds can get in through small gaps and holes in netting but then find it difficult to escape again. This leads to the birds getting distressed, starving and then dying if they are not quickly released. On top of causing distress to wildlife, fines can be given to companies if they have harmed birds in this way.

“The problem often occurs when building contractors are appointed to carry out roof repairs or work on air conditioning units. They take the netting off and then reinstall it and the site manager doesn’t check the netting has been put back properly. It is actually very difficult to reinstall old netting properly so we would always advise new netting is installed by experienced and qualified fitters like Cleankill.”

Pest birds can be cause havoc around, on and inside all types of buildings and if left to nest and breed they are a serious health hazard.

Predator birds

The use of natural pest control using predator birds is becoming increasingly popular at both

industrial and residential sites. Before any action is taken a survey by a professional specialist should take place to identify the species of bird, the problems they are causing and recommend the best methods to deal with them.


All types of buildings can be proofed, from private homes, to churches, industrial premises, offices and blocks of flats. Other areas include water treatment plants, farms, marinas and vineyards.

It is vital that netting is properly and professionally maintained as part of a pest prevention contract.

Bird free gel

This innovative product reflects ultraviolet light. It appears to birds as flames and keeps pest birds off structures without harming them. Rather than acting as a barrier like netting or spikes, the gel alters birds’ behaviour.

Bird spikes

Only stainless-steel wire anti perch spikes should be used and fixed to an ultra-violet treated base. Spikes are fixed down with suitable adhesive. Problem areas include, window ledges, fire escapes, waste pipes, gutters, roof ridges, chimney stacks and pots.

Chimney cages

Chimney cages are made to measure, using 2”, 12-guage galvanised wire mesh. Cages can be made to virtually any size/style, with either domed or pointed tops. Gulls cannot nest on stacks that are


caged. Prices vary according to size of stack and number or height of pots.

Post and wire systems

This system is mainly used on ornate buildings, where it is less obtrusive. It can be difficult to install and take some time. Depending on the base strata, stainless steel rods are either drilled into position or stuck down at suitable intervals. Sprung wires are run between the rods.


A system of speakers, set up to play at random the natural species distress calls, creates an environment appearing ‘hostile’ to the birds. Biacoustics are used anywhere where birds present a hazard to health and safety, or just a plain nuisance. This system is humane, inoffensive and, when played back at a natural sound level, remains un-noticed where the public is present.

Electric bird deterrent systems

Electric systems give birds an uncomfortable but harmless electric shock which deters them from landing. They are ideal where low visibility is a particular priority and are especially useful in protecting awkward shaped signs, parapets, ledges, roof ridges and pipework.

Building cleaning and mess removal

All types of buildings can be cleaned, whether monument, prestigious building, residential or commercial, to rid them of bird dropping mess. All mess should be taken away from site under Waste Disposal Regulations 1994.
