How recurrently do I obligation to spray bug spray? I sprayed bug spray about 2 weeks ago, and about 1 month...

I sprayed bug spray about 2 weeks ago, and about 1 month until that time that around and in the perimeter of my home. I know it's be raining a lot here, and possibly washes it away after awhile. And, be noticing ants coming in again, how recurrently should I spray? Once a month? Or, how often do you spray your home? It doesn't say on the packet. Thanks.
Avacado plant support please?
Answers:    Use as needed. It won't hurt to spray more. Spray once a week just for protection if you want.
Potato planting?
If you can still find it , get Diazanon. Go to dated hardwares. They still might have it. Outside it lasts 3 to 6 months.
