Best products for dealing with ants?

Fellow City-Costers - I need your help! Living out in the countryside has its perks but spring has seen a bunch of ants wanting to take up residence in our house! What are your favorite products to keep the ants at bay? The less strong (but still efficient!) the products are, the better, since I've got 2 little ones and a pup to consider. Thank you!



After spending the last several years in the beating heart of Tokyo, I will be spending the next three in the countryside of Japan. I adore this country and all it has to offer - and I'm always learning more and more about life here as I go along!

    We use boric acid, as it's only toxic to insects and spiders, although it takes a little time to kill them after they come into contact with it. It's inexpensive and we've had a small box for a while and sometimes put some of the white powder around the sliding doors where ants like to come in. (Housan ホウ酸 is how you say boric acid in Japanese.)

    Same thing as hello alissa I bought mine on Amazonhttps://www.amazon.co.jp/gp/aw/d/B002VTK08K/ref=mp_s_a_1_3?ie=UTF8&qid=1524406862&sr=8-3&pi=AC_SX236_SY340_QL65&keywords=%E3%83%9B%E3%82%A6%E9%85%B8 It works well with carpet beetles too

    I should let you know, the powder boric acid on its own wasn't too effective. We had more than a few scouts come into the apartment over the last week, so I researched a bit on how to deal with them. Using the boric acid, I made a "bait" of about 60% sugar and 40% boric acid, plus a tiny bit of water to make a syrup. I put a little in some plastic caps that were in the recycle, then put them onto the balcony, where the ants were coming from. They came and ate the bait, then took it back to the nest to feed everyone, and their visits quickly came to a halt. My husband said they probably communicated to each other that our place was dangerous and found another place to look for crumbs.

    @helloalissa we actually have had a reasonable amount of luck with it so far....they were all getting in from this sunroom area connected to our house, which is full of gaps...so we sprinkled it along the edging and they have stayed away for the most part! If we get an influx of them again I'll give the bait idea a try! I'm just super glad that most of them have left us alone!

Amazon hits and misses

Most of my purchases on Amazon have been household goods and groceries. Kitchen equipment, rugs, laundry and bath stuff. For food, mostly whole bean coffee, condiments, and dried or canned foods. So my question is, for kitchen, bath, and laundry, what purchases have you made that were good value for money? What grocery items do you get?

Your fave autumn leaf spots

I know it's still hot right now in much of the country, but I'm already dreaming of the changing leaves (and cooler temps!) of autumn. What are your favorite autumn leaf spots across Japan? Here in Niigata I really like the scenery and colors around Lake Daigenta which is about a 30 minute drive from home!

Recommendation please for Effective JLPT study resources

Good day and happy summer to everyone! Please spare a moment to share your recommendations for effective JLPT preparation resources. I have been invited to work part time as an Assistant English Teacher even they knew I am not fluent in their language both written and verbal, but it was fun and I made it through. Since then, I came to appreciate teaching here but I was advised that I will be more effective and well compensated if I have an JLPT Certification. Please, would appreciate your recommendation as to where and how to map a successful study and preparation path. Also, I have a plan to volunteer and start up a reading and practice your everyday English in my community which is going to be once or twice a month program. Thank you in advance.
