Mix equal parts sugar and this product and place in a container that you can secure the top of. Sugar attracts the ants to this source. Poke holes in the bottom of the containers so the ants can enter to ingest the product. They will eat it and carry it back to the nest where it will either kill them or render them infertile, there are two schools of thought on this - but it certainly does work even on those HUGE carpenter ants that are downright scary looking. In the beginning, you may need to reapply every year or two. It only takes a small amount of borax. Borax has some toxicity and shouldn't be ingested, it is much less toxic than commercial ant killer, and you don't spray it around the house. Safer for you, your children and pets. Been using it since I was a teen and I'm in my 50's now and still telling people how well it works. It also works on some roaches but since I can't tell one breed from another can't tell you which ones.
Yes - says for all washing machines including "he" here: http://www.20muleteamlaundry.com/detergent-booster/boost-your-detergent/
One thing to note: we just got a front loading machine. It says to put the powder in with the clothes instead of the detergent tray. I'm not sure of the reasoning behind that. My wife put oxi-clean powder in and there was a hardened ball of it that didn't get broken up so just make sure all your solids are not clumped up when putting into the machine. I just put the borax into the liquid tray with the liquid. Not recommending that. Not discouraging it either.
******One thing: check local prices. My wife informed me that this is less than half at the local grocery store from what I paid here.*******
It has been used as a cleanser for about 100 or more years. It was used by my parents 80 yrs ago. You will simply need to try it yourself in that regard. All these modern chemicals produce problems quite often in terms of allergies, as well as toxicity in relation to interactions. KISS principle is best.
