House destroyed with Flying Ants

I have concrete floors, but topped with wood. I think they are in the wall. I replaced the windows and doors about 4 years ago and they have started to appear since that. For example, they guys put a piece of wood to finish the inside of the french doors (I am not explaining this well) but they seem to be underneath that.

Also, on another door, there was a gap behind the hinge (and thousands came through that).7

I never see an ant in the house, its only these flying things, July and August.

I spent 500 on them last year and I dont think it worked - although they stopped, I think it was co-incidence and the flying ant time was over.

This year they are earlier, and although there is not as many of them, there are appearing more often. Early evening, if it has been raining and then hot, they are in their element.

I can see where they actually broke through the mastic on the french doors. Also, a tiny gap on the step path when it was replaced and they spew out of there too. So I filled those gaps with ant powder and sure enough, like Alun said above, they tried another way.

I will definitely look at sealing as many cracks as possible once the summer is over. I only get them at the back as well, its very hot and the sandstone paving is the draw.

One downside of having the south facing back garden, though should not complain.

i am going to try that. I've just been googling it. It seems I should not put any inside as will just attract them in, but leave it outside near where they are getting in. Where can I buy Borax?

Most of the posts are coming from me.

I have had constant flying ants in the house and coming into the house most evenings since end July.

I don't want them in the house and I don't want to come home to the sitting room full of flying ants, so I am looking for advice.

If you haven't got them, happy days. But they are a pest and I would appreciate any advice to get rid.

I dont know what it is called. I'm not that technical. The stuff around the door to fill the gaps.

Funny enough, I dont mind a mouse and we had them in the attics.....these pest things though are on another level, thousands of them. It is the pouring out of the walls that is disgusting.

I woke up at 4am two mornings this week and the ensuite was full of them. They had got in through the part where the window was drilled to let the alarm senor sit. It is a tiny hole and they are all scuttling in.

Yeah I will do......this was a new entry point and its absolutely tiny....its back to the point the poster made about the conservatory, they just seem to find another entry point when one is blocked off and they can fit through the eye of a needle. I had not had them upstairs before.

This heat is definitely the reason for them. And all incidences of them are at the back of the house....where its very sunny. None whatsoever at the front.

Only the flying ants, no actual ants so very strange.
