OK, Let me too tell my story.
It was a few years ago, towards summer, when we noticed some of those <> creatures in our apartment. At the time we put down these stick-ons, the ones that are supposed to kill them and the eggs.. Well, it didn’t. As time progressed so did they. Our apartment was eventually swarming with them. We tried bombing TWICE to no avail. Poison strips. Nothing.
Then one day someone told me about boric acid. So I tried. I poured and poured like there was no tomorrow, into holes and cracks, drawers, shelves, in appliances, under appliances, behind appliances etc. Within a few days they were all B”H gone!! We B”H have not a repeat! HaShem should continue to protect us.
