I want to protect my house against termites, cockroaches and other pests that might do damage or badly affect day-to-day life (e.g. get into food or take over parts of the house).
However, I also don't want to kill insects around my house if I can help it e.g. ants, bees and other insects in my garden or around my neighbourhood, or have chemicals that are deadly to insects or birds and fish leach out into local waterways.
I think the previous owner must have sprayed a barrier spray recently enough as I've found some dead spiders and insects around the house since I moved in.
Any advice on achieving a balance between pest control and not causing environmental damage? I was thinking of using diatomaceous earth for now to keep out ants from my doorway, but other than that - if I do use a spray, where's a good place to spray to minimise the impact on insects and spiders outside? What brand or type of spray might be good to use?
