Ant on ice

When do ants wake up from hibernation?

As it starts to warm up in the Spring (or even late winter) ants will start to become more active in their nests. Some will even venture out onto the snow if it’s sunny enough.

After four or five days of above freezing temperatures (+5 c / +41 f) you could start to see ants inside your home.

At the first sign of ants in or around your home you can start to take action:

  • Identify the entry points (where they’re coming in)
  • Identify the attractants (why they came in)
  • Clean up entry points and areas of attractant (using Windex or any strong smelling cleaner)
  • Place bait at entry points

Remember: There is never just one.

  1. Had ants in my entryway two weeks ago. Bait took care of them immediately. Now finding them in my bathroom tonight. 🙁 have put out more bait, hope it works

  2. You must be somewhere warm if you’ve got them already… 🙂 Thank you for commenting and good luck with those little guys. See if you can follow them and tell where they come in the house, the best place is stop them is at their entry point.

    1. I had a similar situation a few weeks ago. It turned out a few ants had come in the house, inside a potted plant I had placed next to the sink. Any plants near by ?

  3. I live in an old hotel building in Oakland, CA and ants are a definite problem here. As you said, it’s impossible to kill them all so the best I can do is clean, clean, clean (which I should be doing daily anyway, so the ants def help me accomplish that chore), NEVER leave out open containers/food, and kill scouts when I see them. Anyway, earlier I accidentally spilled some Red Bull, easy clean-up it wasn’t that much. But ooooh boy was it like crack to the ants. Within minutes, my room had several trails etc etc. Thanks for the site, it provides some info I didn’t know, and a reminded me of some other techniques to keep them at bay as well. My dilemma right now is that I ran out of bleach-bassed cleaning spray that is the BEST for ants and the only disinfectant-type cleaner I have left doesn’t keep the ants from coming back literally minutes after I’ve wiped up and thrown away the trail of ants and their companions nearby. Yeeeeeesh! So frustrating. I guess I’ll have to go buy more bleach-based spray (for the trails, clean surfaces etc), bait, and duct tape or something like it (to plug-up crack and holes the ants use as an entry point). Anything else I should do/get from the store??? Thanks!

  4. Yesterday I had a lot of ants in my window I left a cup of juice the edge of the window they went crazy I got up and kill them and clean the area with bleach today I got up and bleach my whole apt I’m not done yet

    1. Hi Isis,

      It’s that time of the year, that’s for sure. Let the battle begin! Let us know how your bleaching efforts work. Good Luck.

  5. We’ve been getting a random ant maybe two in the same area on the wall every night starting April 14th ish. Then tonight (4/21) there were like 4-5. It’s near my range so I pulled it out no signs of infestation. I checked everywhere no new plants I even sprayed the perimeter of the house with ortho. Granted it was a warmer winter this year so maybe I waited to long to spray. But I still have no idea where they are coming from.

    1. Hi Zach,

      Sometimes it’s really tough to figure out where they’re coming from. It’s unlikely they’re nesting in the house (they almost always nest outside – underground). Let me know how your battle goes. We would appreciate any info on what works and what doesn’t work. Good luck!
