I've been using Bifen IT here in the Dallas summer heat and it's been doing ok. I spray on concrete, around our house and all of our flower / garden areas. We live next to a pond/lake and trying to control mostly spiders, mites, mosquitoes, silverfish, fire ants, crane fly.
Bifen IT is a great product for all the insects you have mentioned, but another good product to be used outdoors is Cyzmic CS. That is because Cyzmic CS has a CapVantage Micro Encapsulation which means that each droplet of insecticide is encased in a protective microscopic capsule, providing a long residual, even in direct sunlight or other harsh weather conditions. The only insect Cyzmic CS is not labeled for that you mentioned is crane flies. Most products are still only going to provide a 30 day residual outdoors in the summer. Be sure to check out our Pest Guides for more details about the most common structural pests.
