Review on 3-Pack Large Clear Empty Plastic Storage Jars with Lids - Half Gallon Square Air 🏺 Tight Containers with Easy Grip Handles - BPA Free, Food Grade, Wide Mouth Jars for Multi-Purpose Use by Christine Rogers

Used cans to make traps for small insects that walk around on the ground. I cut a hole in the lid, stuck a funnel down the neck of the jar, and let it drain into the bottom so it wouldn't flood with rain. I replaced the lid, now a ring-shaped one since the hole was taken from the center, and screwed it in place along the edge of the funnel. Prevents small mammals from opening the trap and eating the catch before I get there. Since the traps were set, I have collected large numbers of beetles that have long been considered rare in my area, but now have a wide distribution and abundance, which is also a new national record for another species. An example of low-budget citizen science. These jars fit perfectly in a funnel available at my local hardware store, hold lots of samples unlike regular deli jars which are buried to the brim, protect contents from animal raids and in just a few weeks of use have helped reduce the to change the way we think about two native species of insects. I'm sure they would make great food storage containers too.
