How to Make a Spider Vacuum
If you're like a lot of people you would love to find a way to get rid of spiders without having to get close to them. Consider making a spider vacuum, or spider rifle. The vacuum uses a long tube and compressed air to suck the spider into a chamber that can later be emptied outside. Making one is simple and costs much less than the spider vacuums you see advertised on TV. No special knowledge is required. Just a few materials and tools and little bit of time can make the perfect bug catcher.
Step 1: Make the Handle
You will need to begin by cutting your PVC pipe. Using the hand saw, cut two 4-inch sections, a 2-inch section, and one 18-inch section of the PVC. Attach the two 4-inch sections to the 90-degree fitting with the PVC cement. At one end of the handle, cut a 1-inch, centered notch down the sides of the pipe. Take the hose clamp and slip it into the 1-inch notch. This clamp will hold the can of air. Glue the 1-inch end cap over the end with the hose clamp.
Step 2: Make the Barrel
Start by drilling a 1/8-inch hole in the top of the T-fitting. Using the PVC cement, attach the 18-inch pipe to one end of the T-fitting, and the 4-inch handle to the other end.
Step 3: Constructing Bug Chamber
Glue the 2-inch piece of PVC to the bottom end of the T-fitting. To the end of that, glue the 1/2- to 1-inch coupler. Attach the 1-inch piece of PVC pipe to the coupler, but don't glue it, just push them together.
Using the 1/16-drill bit, drill as many holes as possible into the 1-inch end cap, and then glue it to the free end of the 1-inch PVC pipe.
Step 4: Making the Vacuum
Fit the can of compressed air into the handle and hose clamp snugly and tighten the hose clamp. Insert the tube from the can of air into the hole at the top of the T-fitting and the other end of the tube to the can. Glue around the tube to secure it to the T-fitting.
Now you can use the vacuum to suck spiders into the bug chamber by aiming the end of the gun at them and spraying the compressed air trigger. Once you have captured your spider, you can take the gun outside and remove the bug chamber (the 1-inch PVC piece that you did not glue) and release the spider. Reattach the 1-inch pipe and you're ready for your next hunt.
