How to get rid of tiny ants?

Keep the house clean from food as much as possible. Clean counters, tables, and floors often, and put food away in air-tight containers or in the fridge. Leave Terro out for them to snack on at all times.

Ants are particularly tough. We've fround Bayer brand of spray to be effective, at least for now. In a few months, we may need to change to something else. We get it at Gallows Bay Garden Center.

Terro!!

I was impressed with Terro the first time I used it (on our boat), but using it on land, for some reason, hasn't been as effective. I wonder if it's because I bought the first in PR, and maybe it's a weaker formula here? Not likely, but it is possible the formula was changed between times. Anyway...as I understand it, if you have an ongoing problem, or you just spray monthly as a preventative, you need to change what you use occasionally. The critters become immune, just like if humans use too many antibiotics.

@Uuaww, you could always call in the pros. However, one of the sales people at GBH told me at least one of the pest control companies here never changes the formula, so they don't work after a while. I have no idea if she knew what she was talking about, so just take that for what it's worth.

Flamethrowers work nicely as well.

I seem to get an invasion of them after every heavy rain. Normally, they aren't interested in me or the cat's food or any other random crumbs. I just get the Terro back out and put it in their (new and esoteric) path and a day or two later, they are gone again. I am somewhat on the psycho side when it comes to keeping my house clean, though. Perhaps that helps? I lived in Florida where we would have the same sort of home invasions. Good luck!

Are the ants sugar-loving ants or savory-loving ants (I know this sounds strange)? Depending on which ones you have, you may need to use a different formula. I think terro works best for sugar ants? When I had ant problems in Florida, I used to buy a a blue gel that I would mix with a drop of oil to attract and kill the savory ants (they were eating cat/dog food, not sugar). It did seem to work. Also keeping your drains and countertops clean helps too.

We get the regular ants after heavy rains. They come in, walk around for a while and then leave. Ocasionally they do get into the garbage. We spray, but I'm not sure if they leave because of that or just because they do.

Terro

Use Terro but be prepared for the fact that it will only be a temporary solution; you will find ants every now and then despite your best efforts.

A couple of years ago we had some kind of an ant "swarm". Woke up one morning to find then all over the LR and kitchen, stacked up in little piles,mostly dead. Weirdest thing I've ever seen. Never has happened since.

Where are you living?

I am in the rainforest and we get the crazy ants. I use terro and it works well. Spectricide and Hot Shot did nothing. Basically, I line the veranda and the window sills with it to keep the ants out. However, I have to put the terro down every two days or so. I am sweeping up a gazillion dead ants every morning and they stink! They seem to migrate to the corners, pile on top of each and die.

From what I have read, there is a population explosion happening on the island of the hairy crazy ant.

i know itsa bit late but grits work very well as a non pestiside approach and theyll die when they go back outside and kill a few queens when they take it back to the nest. theyll all drink water and just explode! lol
