Ah, another addictive game! I'm always a fan for survival games. I was challenging myself to survive a bit more longer. Then I kinda cracked it. I stay at the top and a little bit to the left and the bugs will always generate from the lower right side and my mouse just kept clicking it there.

Top right also works. They quickly dart in the player's opposite direction just barely off screen. It's more obvious when you aren't at the top that they try to move away from the player and then attack. (I probably should have actually used pathfinding instead of lazily making an invisible target for them to follow.) I considered adding a hint to stay at the top in the tutorial but figured most people would figure it out.
