Hidden Mosquito Spots in Knox, IN Yards

Most people know, on some level, that mosquitoes come with water. They figure mosquitoes need a lot of it, so they scan the yard for obvious sources of it and call it a day.

Out here in Starke County, with Bass Lake and Koontz Lake and all that low, sandy, lake-country ground, there's plenty of obvious water to blame. But the truth is that the water sources where mosquitoes typically breed are usually small and stagnant.

That’s what makes Knox mosquito control frustrating. Mosquitoes can complete their whole life cycle in water that won’t even fill a coffee mug, which means the source is seldom the lake. It’s all the water sources under your nose.

When it comes to Knox mosquitoes, these are the places that always get missed

When in doubt, start here:

  • Corrugated drain pipe and downspout extensions. Those ribbed plastic tubes hold a little water in every ridge.
  • Tarps and covers. That includes the grill cover, the boat tarp, and the woodpile cover. Any sag holds a puddle, and a covered puddle stays warm and undisturbed.
  • Tree holes and rot pockets. Older trees develop hollows where branches meet the trunk. They catch rain and hold it for days.
  • Plant saucers and potted flowers. The dish under every pot on the porch. Even a half inch is enough.
  • Clogged gutters. Out of sight, full of leaf debris and water, breeding mosquitoes twenty feet over your head.
  • Low spots in the sandy soil. Knox's ground drains oddly in places. A shallow depression that holds water two or three days after a rain is plenty.

None of these sounds like it would create a mosquito problem, which is part of why it’s so tricky. Check these first before you point fingers at the lake or the marsh.

Why "just dump the standing water" only gets you so far with Knox mosquito control

Walking the property every few days and tipping out everything you find is genuinely good advice. We tell everyone to do it. It's free and it works on the sources you can reach. But there are limits to how far that advice can go.

You can’t drain a tree hole or clear a downspout buried under the deck every three days. And in the lake country of Knox, there is always water nearby that isn’t yours to manage at all, from marshy edges to neighboring lots. Mosquitoes don’t respect property lines. They’re fine to breed next door and then come bite you in the evening.

Knox mosquito control for the places you can't reach 

Our mosquito barrier treatment focuses on the shaded foliage and resting areas where adult mosquitoes spend their day. Mosquitoes rest for most of the day, so we treat those surfaces. When they land on treated surfaces, they’re then knocked down. This works like a charm and can reduce the mosquito population by up to 90% for 21 days at a time before re-treating.

It works a lot better than hunting for every hidden puddle yourself.
