We own our house and adjoining neighbour had some building work done in recent years. Anyway to cut a long story short we have rats in our loft area and we have also heard them in the cavity wall areas etc.
We ourselves haven’t seen them but have heard them frequently and loudly. We have had several private pest controllers out and they have put poison down, the rats go mad and loud afterwards, then it quietens down (I go mad quietly worrying that the slightest noise is them back then they always do come back). This has been going on for a month and our adjoining neighbour's have also used one of the same pest controllers and put own poison down. One of the pest controllers thinks they are most likely coming from a damaged drain on neighbours side (he has advised him of this). Neighbour has started to make some half baked DIY attempts to make his property secure (but his garden is a total mess with discarded building Materials absolutely everywhere-which won’t be helping matters). This week we found out he had two dead rats in the lane on the other side of his house and a couple running about in the same area during the day (younger rats and not running fast). We have spent £’s on this so far but its not sustainable and we are more bothered by them than the neighbours who claim to not hear them.
Should we persevere with weekly rat poison from pest controller and or buy some ourselves and use it for ever more or what happens if we inform environmental health (what powers do they actually have). This will no doubt cause agro and I don’t want any trouble from him so far he has been okish over this but he can be volatile and would hate to get on the wrong side of him. But equally I am not sure how much more of this living in fear of the rats I can take.
