It is very simple to deter seagulls with a Green laser, these are easily available from the web – look for 532 green.  The green laser triggers the seagulls flight/fight response and pavlovian conditioning will train the seagulls to go elsewhere.

The best deterant time is dawn or dusk in January to May before they have nested and if they are around from August to December – an area can easily be cleared and the seagulls will go elsewhere.

Some folk may not understand what the DFL’S green light is and to avoid ending up in the local’s Wicker Man or a similar Peter Grime’s fate ensure you use the  laser lawfully and legally :

Don’t point at cars, airplanes, people, animals, into  houses etc.

Don’t use whilst their are chics.

Generally people have an aversion to seagulls because of their scavenging, noise, soiling, attacks, rubbish spilling etc – but remember some folk like them, feed them and make pets of them and so understanding is also called for and care in theIr use.

Party Wall Act – The Act suspends common law (but remember much common law has been supplanted by statute) but where not The Surveyors may deter seagulls if required and if so a Green laser is recomended.

Building Surveys – If you have purchased a property which is subject to Seagull nuisance and your surveyor has not advised you they are negligent.

Seagulls – like all pests can be removed by simply breaking their cycle which by observation is not unsimilar to rats etc (egg, larva, pupa, and adult) – but I categorise seagulls as follows – Colonies seek weakly or unprotected areas, Colonise, roost, sex, nest, egg, hatch, fledge.  Seagull also have a language associated with each.  The laser is the ideal tool to break these cycles and remove them.
