Crazy Ants...

Don't know where your located but most pest control companies have TOP CHOICE (made by Bayer) available. It's a fire ant treatment but works on ALL ants. It's pricey... Usually around $250-$300 (up to 2000 square feet usually) for a normal sized yard but guaranteed for A YEAR!!

For inside your home.....use a bulb duster and boric acid. Take your wall socket /switch covers off and dust inside them. Dust around your water entry points (where water pipes come out of wall... Under sink)....dust your window seals/crevices....dust your weep holes outside your home if it's a brick home. If it's a mobile... Lay down a barrier of boric acid around your skirt.

Sprays typically don't work well on crazy ants or sugar ants (as a deterrent ) unless you make direct contact. They will avoid them. Sucrose/sugar based Baits from Lowes/Home depot work better.
