yes, ALWAYS remove scent trails of EVERY creepy crawly.
We had two 2 liter bottles of soda explode inside a base cabinet in our entertainment room. What a mess! Didn't discover until the next day, ran down inside through cracks disappeared into ?? But the ants found it! The cabinet isalong an exterior wall, duh!
Used the fastest thing I had around, Raid's new Bug Barrier. Sprayed around, down into the same leaking cracks etc. Never saw anoth ant for over year now. I think that stuff kills the next even.
It is a commercial toxic, "spit, spit, curse be gone!" but it DOES work and work well.
