For some reason yellow meadow ants have developed a fascination with a certain interior wall in our house. The usual gels, powders and sprays are having little effect. They do slow down for a while but just appear again further along the wall.
In part this has been caused by the sealant coming away between the skirting board and floor. Clearly I should replace this, but would caulk (or something else) be better at deterring ants in the future?
Also, any other advice on how to eradicate or otherwise slow down their progress would be appreciated in the meantime.
