I have lived in my house for two springs/summers now and each time when the weather heats up it seems like the fruit fly type bugs just start spreading around the house like crazy, mostly from the kitchen. I have a regular pest control guy and he suggested pouring bleach down the drains. That, combined with a trap using apple cider vinegar seems to contain them sort of well, I have to pour the bleach down the drains on a regular basis and redo the trap as it fills up quickly. Also, I make sure to put away all food so it's not like I have a bunch of stuff out on the counters.
They obviously hang out/breed in the drains and my kitchen has a sink with two drains (really both meet up and go down the same pipe) and I don't have a garbage disposal.
Would a disposal help at all? Is there anything I can do to keep this from being a problem again? The weather is heating up again and I really don't want to deal with this another year.
