Get yourself a good backpack sprayer. They cost a little more than a handheld, but are much more comfortable and will save you time doing refills. I have had this one for years. Even my girlfriend has used it on one of her rentals and had fun using it. https://www.amazon.com/Professional-190328-Backpack-Sprayer-Killing/dp/B000AYHKUO/ref=mp_s_a_1_5?crid=3G5L170C26MJH&keywords=promax+sprayer&qid=1657669630&sprefix=pro+max+sprayer%2Caps%2C181&sr=8-5
As someone else mentioned, Cykick works really well for most of the bugs you don't want coming inside in AZ. I tried Demand CS but had better luck with Cy-kick.
This looks to be the current version of the one I have. I’m on 10 acres and use it primarily for spot weed control and glyphosate in and around all the beds. I used it on my gravel drive before I paved it. I’ve had it a long time and while it’s not expensive it’s lasted much longer than I expected. Still going strong after I don’t know, 10 years?
