Living in a house with high ceilings and clerestory windows is usually a good thing, but when flying or crawling pests -such as flies and spiders- invade the house, they tend to head up to the high corners, out of reach of the bug spray.

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

 What You Need(fig 1)
1. A long piece of dowel or old curtain rod
2. String
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
8. Scissors
9. Small piece of Blu-tak/plasticine
10. Rubber band

Very resourceful. I do hate it when they get so high up
I like your patent!<br> <br> I used a different approach on old fashioned spray-cans:<br> <br> I cut off the top of the cap, leaving around half an inch all around, make two holes -opposite each other, run a string through the hole, over the trigger and through the other hole. Superglued the string to the top of the trigger. Tied the ends, making it a loop and duckt-taped the whole thing to a broomstick.<br> <br> And then you direct at whatever you need sprayed and pull the loop, depressing the trigger.<br> <br> See sketch, seeing the whole thing from above -arrow indicating spray and 45 degree line is the string depressing the trigger in the center. Pole in the upper right corner.
Nice idea! It's such a pain when your spray won't reach! Your technique sounds very inventive- maybe you could get some photos and write an Instructable?<br><br>We get huge hairy spiders here and they run right up to the highest spot. I hate to kill them, but sometimes I can't stay in the same room, so I have to do something. <br><br> (My other technique was to get extra tubes to extend my vacuum cleaner; this works well for spiders but it's the blow flies that are driving me mad at the moment :i)
