We live in Texas also, where "everything's bigger in Texas", including the bugs (and plenty of 'em, thanks to the climate).
And I'd like to heartily second the recommendation of Bengal brand as the *best* bug spray you can buy without a license.
I've tried others, including the "big name" brands, and often even a point-blank blast right on the running roach, soaking it, will have no noticeable effect at all. I even trapped one under a glass overnight after such a treatment, and it was spry and healthy the next morning. And that's after having gotten covered in hugely more bug spray than its friends in the walls would ever get from a treatment.
Bengal, on the other hand, *kills* them on contact, and is strong enough to wipe out the ones deep in the walls or behind the furniture, too, in one treatment.
It costs a lot more than the other brands, but it's entirely worth it because it *works*. Plus a little goes a long way, you don't need to keep re-spraying. I haven't bought any other brand than Bengal in years. Great stuff.
Which Bengal fogger would you suggest for spiders? They have two kinds on their website: Roach and Flea fogger, and Flea and Tick fogger. Problem is they both have the same descriptions. They both say they kill spiders but they must be different products otherwise why list them as such? Thanks!
