Ants getting into cage

Question
A few weeks ago I bought two parakeets, Rain and Dew. I had them in my room until recently, but had to move them out because I found out I was having allergic reactions to them. We moved them to the living room and they seem to be doing fine.

Unfortunately, where I live, it is that time of year when ants are everything! Yesterday I found at least 2 dozen ants crawling at the bottom of the cage, on the outside, and on the table where the cage sits. I guess it is because the birds keep throwing seeds out, and are attracting the ants.

I have cleaned the cage, replaced the food, and clean the area where the cage sits, as well as kill the ants. So now the cage is ant-free at the moment.

I am worried that later on the ants will come again. Can the ants hurt my parakeets?? Is there something I can do to keep the ants away from the food and floor of the cage?

Thanks =)

Answer
Dear Yesenia,
thank you for your question.
Most ant species cannot vaseline barriers. Try smearing vaseline on the legs of the table or on the bottom part of the cage, a barries that's one inch wide is usually enough. That should stop them from coming into the cage. Oil works as well, but has to be re-applied more often than vaseline.
I hope I was of some help to you
