Diy extermination tips

[Sami Gren]

Hi, I was wondering I am paying so much money for exterminators and I see that what they're doing you need no extra skill it's just the knowledge  I was wondering if there's someone here that can help me out first of all with roaches what type brand of bait can I buy and how do I apply. And also about mice I saw them throwing such small type of poison I was wondering which one this is that  is effective.

thank you
