A few days later there were more ants, so I used caulk to seal the gap between laminate floor and skirting board trim, this appeared to do nothing other than give the ants an excuse to find any possible gap that was left in the vicinity, which they did, including 1 super-ant who appeared to break through caulk (he must have had his weetabix). In tribute to that particular ant, I let him escape outside, a mark of respect for what he had done, with a warning that a re-appearance would not be tolerated, I would assume he heeded the warning, if he did not and was caught in the battle mentioned below, RIP super-ant. Basically, caulking the gaps was not working, so much so, that they ended up coming through under the door between lounge and conservatory, which was a total pain, this was now time for a proper battleplan. Stage 1 = This involved lifting up the carpet in the lounge, and placing small amounts of ant-powder all across the edges, followed by a spray of 'Dethlac' a double solution you could say. Basically any point they were getting in there from, was blocked with powder and spray. Put the carpet back down (gently, so as not to get a cloud of ant powder in your face) That ended their advance into the lounge, and kept them inside the conservatory, where I had deliberately left 1 small hole near the skirting, every so often, I would see an ant poke its head out of there, and have a wander around. That to me, meant, the problem was not solved, merely slowed down. Stage 2 = Find the entry point, given I had not seen any obvious routes into the house, and had placed ant powder outside the entire perimeter of the conservatory, without success, the only place they could realistically be coming from, would be under the patio door (again, this was not visible but seemed the only plausible route in). Out came the Dethlac, sprayed under the outside of the door, including the gaps around it, and the gap between the door opening/sliding part. The result, no more ants. I had been recommended Dethlac, by a family member. and noticed it was not readily available in the usual stores, and whilst I am not saying other products would not work, it would seem Dethlac is the best, certainly in my experience. I will probably re-spray the area every 2 months or so, over the summer, and that should hopefully keep the ants away.
