Hi, so, I wanted to ask about something, as I mentioned in the first post on this forum, I used to keep ants about 2 3 ( I was also surprised when I learned 2018 was 3 years ago ) years ago, and my house been previously the foraging ground for a Lasius niger colony ( I will never forget when they marched en masse through the house's kitchen ), and during summer and spring 2019 2018, the ants were surprisingly non-present, before returning Spring 2020 2019, and I wanted to ask has anybody experienced anything similar in their house and what could be the cause of such a thing?
