You can try to pump clouds of spray into the air and hope it reaches high enough, but that’s wasteful, ineffective and not healthy. Or you can climb on a chair and try to reach, but the flies just fly away, spiders tend to drop on you, and you’re risking a fall.
I pondered the problem and came up with a simple extension handle for a can of fly or spider spray to deliver a burst of spray right at the pests.
This could also be used outside to put surface spray under high eaves etc- but please consider the wildlife such as birds who may feed on the bugs and spiders, before you spray poison around.
Step 1: What You Need
1. A long piece of dowel or old curtain rod
3. A small clothes peg
4. Insect or spider spray- see picture for can type (needs to have the “enclosed” type top – see fig.2). You can get a better quality spray as you only need a small amount at a time, since you are spraying right at your pest, not vaguely somewhere near it!
5. Tin can – tall, thin type to fit the spray can
6. Cardboard- e.g. cereal box
7. Duct tape
9. Small piece of Blu-tak/plasticine
10. Rubber band
