Jeff from Manteca, Ca writes

Should I continue using Bifen I/T or switch to another general purpose insecticide?

I am currently using Bifen I/T for my exterior home spraying every 3 months. The bottle is nearly empty and I need to purchase more. Would it be best to continue with this product or switch to another product? I remember reading that insects can build up an immunity so it is good to change from time to time. I have had very good luck with Bifen I/T in getting rid of my ants and spiders. If you do recommend changing, then what do you recommend? Thanks!

Answer:

It normally takes many years for insects to build a resistancy to insecticides. If you are still experiencing good results from Bifen I/T then I would recommend continuing with Bifen I/T. The price and effectiveness cannot be matched.
