Unless, of course, the 'insects' in question consist of piles of dead or living ants whose bodies or corpses clog the passageways of our feeder!
So i was forced to design and construct and to elucidate upon a device that prevents such a situation: the "Anti-Ant" Ant-Blocker!
Shall we begin???
<Responding to the 'whooopwhooop HURRAY's in the crowd, i yield!>
Step 1: What you'll need
wire-tie (strong, maybe 1/4" wide; I used 'Removable' wire-tie cuz i had a few)
flat-blade screwdriver (width of blade about same as width of wire-tie)
Block of wood (or other support upon which to place the empty tuna-fish can)
empty tin-can .. (catfood? tunafish? truffles? Aluminum best, won't rust)
Sugru (or any other moldable material that is water-proof and sticks to metal)
Hummingbird Feeder, of course.
(Not shown: a Hummingbird smiling at his/her ant-free feeder)
Glass of wine (i suggest a fine red .. perhaps Merlot. whose color blends
well with the coloration of the Ruby-Throated Hummingbird
And of course, a good aged cheddar and crackers.
