Yay! The expert showed up!
Glad I got it right
...but what route would you recommend alternatively?
Lol I am by far an "expert", but I do know a quite a bit

I no longer do that kind of pest control though.
Do bases provide pest control? If so, the best route is to have a professional come in, asess the problem areas(most larger companies usually will do a free inspection), and treat it accordingly. Also.. pest control nowadays is done differently than it used to, most problems can usually be solved without even using pesticides.
It simply involves taking the three things they need to survive
1)food- crumbs, grease from cooking, loose dog food, treating a host animal(frontline/advantix are good ones),pulling a stove out and cleaning around it is a HUGE one for roaches,etc.
2)water- standing water, leaky faucets, leaky pipes.
3) shelter- exclusion is a big factor, sealing up gaps where pipes come in, gaps around doors/windows, leaving doors open, holes in window screens.
Once you take everything away from them it is much easier to get roaches and ants to accept baits.(with baits, there is hardly any chance of secondary poisoning if consumed by another animal or even human)
I cannot comment on sand fleas as I have no experience with them, but a Local PMP(pest management professional) will know what needs to be done.
