Onslaught FastCap Spider and Scorpion Insecticide would be a great choice for spiders indoors and outdoors in New York State. It is mixed at 1 oz per gallon of water and the pint-size bottle will treat 16,000 sq ft providing you with a 30 day residual outdoors and a 90 day residual indoors. You will also find that it treats over 200+ other insects.
