We lived in HA housing in a rural community of about 40 houses. The lady next door to us moved in about 18 months ago and seems to be a very nice and polite person. However about a year ago she started a hedgehog rescue which is very commendable. We thought that charities which are a business were not allowed to operate from HA properties. However she is not removing droppings regularly or disinfecting and piling up bags and bags of their compost. Consequently in summer we had a plague of flies and blue bottles plus on hot days a terrible stench over the neighbourhood. It is now winter and for the first time in 8 years we are still having an issue with flies and bluebottles. Yesterday she had another load of crates delivered which means even more hedgehogs on a piece of ground that is not larger than 65sq metres. This is of concern to us especially as I have rheumatoid arthritis and my immune system is low. Hedgehogs apparently can transmit salmonella to humans because of the bacteria in their droppings. I not sure if it can become air borne, but I am wondering why I have been suffering from a sore stomach for awhile plus other issues. Just to add we have 3 Yorkshire terriers and 2 cats. Only one cat ever leaves our property but never goes next door. The pets have been with us for several years. We want to issue resolved but do not want to fall out with the neighbour so are not sure how to approach the matter. Please advise. Thanks.
