We recently had an episode of fruit flies congregating in the kitchen. We looked up some natural ways to get rid of them. We tried sitting jars of apple cider vinegar with drops of dish liquid out to bait them. We even set some out with just the vinegar. They were drawn in, but they were obviously too smart to land in the vinegar. Guess we should have used a funnel. We ended up loading the dishwasher and leaving it unlocked overnight. In the morning, we turned it on and poof, no more fruit flies.
Just thought I’d share this lil’ tidbit of domesticness with y’all.
I read and value each and every comment and I visit those who comment... even if I don't comment back. I'm working on it, I swear! Stuff you should know *ehehm*: So... sometimes companies send me items of interest in exchange for a feature on my blog. Some also compensate me for my time and efforts creating content to promote them. Yay! I always disclose if I have a relationship with a company. If I don't disclose a relationship with a company and I link to them, then the link is most likely an affiliate link. I use a plugin that automatically does this for me. Cool huh? Just want to make sure you are aware :). Read my full disclosure policy
