Ah, how well I know this problem……
Try diatomaceous earth. It’s not poison – it’s the dried shells of some tiny little creature of some sort, and while it’s not harmful to you and yours (or your pets), it IS harmful to any insects that crawl over it – ants, spiders, earwigs, beetles, etc, etc, etc. It’s like tiny shards of glass that they walk over, and it cuts them up so they die. Sprinkle/dust it around the outside of your house, even around doorframes, around your garden (be aware this will cut up the good insects, too), and you can even safely use it indoors (just use a dust mask while applying, as any fine dust will harm your lungs if you breathe it in).
BTW, do not get the pool quality – make sure it is for pest control. 🙂 In my neck of the woods, Ace was the best price, but I had to order it online. I got the Safer brand (a yellow bag).
