How long will Martins Permethrin 10% be effective when sprayed for spiders?

I sprayed under my house for spiders and was wondering how long its effectiveness will last?

Answer:

Martins Permethrin 10% will likely last up to about 30 days in optimum conditions. If you would like a longer lasting insecticide, we would recommend an encapsulated product such as Cyzmic CS. In a crawl space, you could also use an insecticide dust such as Delta Dust, which is a dry formulation that lasts about six months.
