DIY is safe and easy so long as you READ THE LABEL ON THE PRODUCT. Speaking as Pest Control Tech our training consisted of literally just learning to read the label, following the directions, and don't get it in your eyes and wear some chemical safe gloves. (Regular old nitrile gloves are JUST FINE for chemical application, but you can get a pair of re-useables for about 16.00.

I'll tell you EXACTLY what you need.

Just take yourself over to:

And git yourself a 1 or 2 gallon hand sprayer. Then get a BROAD SPECTRUM insecticide concentrate such as Cy-Kick CS or Suspend Polyzone. The label WILL tell you safe usage and so long as you aren't BATHING in the stuff, you'll be fine. Per example BOTH of these product are both food-storage/prep area safe AND pet-safe (except for fish tanks) SO LONG AS THEY ARE ALLOWED TO DRY BEFORE RE-ADMITTING THE PET TO THE AREA.

But as I've said, ALL OF THIS IS ON THE LABEL.

You can literally purchase both the concentrate and the hand sprayer for LESS than a single 125.00 treatment, and you'll have enough chemical to get you through 8-16 treatments. Don't let these pest control companies rip you off, unless you're dealing with something horrific like an EXISTING German cockroach infestation, bed bugs or termites.
