Insects are fascinating creatures, but they can also be very difficult to study. They move quickly and rarely stay in one place for a long time. This build can help you get a closer look at insects while still allowing them to be let free when you are done.

Materials Listinsect aspirator homemade

  • Clear vinyl tubing
  • Small Jars with lids (using Baby food Jars)
  • Cotton Gauze
  • Rubber band
  • Drill bit to match the size of the tubing. Since my tubing was 3/8″, I used a 3/8″ drill bit. If you use a straw, 1/4″ or 5/16″ might be more suitable.
  • Drill.


  1. Using the sharp tip of the drill bit (maybe a thumbtack or pin if it isn’t sharp enough), carefully poke two guide holes in the lid of the container. Make sure they’re far enough apart that the holes won’t overlap when they’re drilled.close up of the rubber band around the tubes
  2. Connect the bit to the drill, this should be pretty self-explanatory. Have a parent do this for you if you’re inexperienced with a drill, it can be dangerous. Drill the holes carefully and smoothly. Be very cautious, starting light and slowly adding pressure. Instead of yanking out the bit when it’s through the lid, change the direction of the drill and slowly guide it out.
  3. Cut two pieces of vinyl from 3.5 – 5.5 inches.
  4. Put the tubes through the openings.
  5. Cut a gauze square 2” by 2”
  6. Using a rubber band, place the gauze square over one of the vinyl tubes.
  7. Screw on the top and you are done!
