Do Different Ant Farm brands do better than others?

I tried two ant farms before from uncle milton (one gel another sand) and I want another but since all the ants died in my past ones im not so sure. Is there anything that I could have forgotten to do(i fed the ones in the sand one)? Is there a better brand? Antworks, maybe?

What kinds of household and farm products and chemicals will cause a fals positive u/a for meth besides meds?

I have been able to locate a list of all over the counter medications that will cause a false positive urinalysis for methamphetamines. I need to find a complete list of all prescription drugs, and any other household of farm products that can cause such results if they get into a persons system. This data may be the only thing that saves me from loosing custody of my son for something I have not done.
Just for those who have left accusatory answers, allow me to reiterate. I have not done drugs. I am asking this question because a false positive ua caused my son to go into Foster Care, and I’m trying to prove my innocence so he can come home. This bullshit caused me to miss his first b-day. So if you know of anything that may cause a false positive, let me know. I’m trying to compile a list of anything I may have come in contact with so the lab can cross check and prove my innocence.
