Wasps are insects that are considered pests to humans. This is especially true when wasps build their nests in areas where there are a lot of people. Unfortunately, there are many structures in our homes, such as underneath the corners of roofs, that are often seen by wasps as great places for nests. Once nest has been built or established, a wasp problem follows. In such cases, considering what makes a good wasp catcher is important.
Good wasp traps or catchers are available on the market. However, you can also choose to make your own. What is important is that it meets the criteria for trapping and killing wasps. The first criteria that needs to be met is that the wasps should be able to go in but not come out. This should keep the trapped wasps isolated. You don't want them to be able to get out and get to you because angry or aggravated wasps are very likely to sting.
Second, consider the wasp design. Some traps have ledges, and these can be good and bad. They're good because wasps can rest on the ledge and this could mean attracting more wasps to the trap, but they're bad because most traps with ledges near openings are the type of traps wasps can escape from. Also, consider what means of protection your trap offers and how easy it is to rebait the trap. Most traps need to be rebaited every two weeks in order to stay effective. If your trap can ensure that the wasps will die before you rebait or protect you from the wasps while you rebait, then this is good. Just keep in mind that if you have a trap full of wasps and some start to rot, you have to clean it out and rebait, even if two weeks aren't up yet.
Try not to use meat as bait for your wasp traps. Although wasps are attracted to protein, meat can start to rot and stink after a few days which will only attract flies. Not to mention it will be pretty disgusting to clean out. Anything sweet and liquid will make good bait, and if you can lace it with some kind of poison, even better.
The best wasp catcher is a wasp catcher that can kill all the wasps that go in, even if it doesn't trap a lot of wasps. There is nothing worse than a trap that attracts tons of wasps but can't kill them all. You'll only introduce an even bigger problem. To try and avoid this, set up several wasp catchers leading away from your home or the problem area so that you not only catch more than the usual, but you're also leading them away.
Some people believe that a disposable wasp catcher is safer because you don't have to deal with the captured wasps. While it is more convenient and somewhat safer for you, you do have to consider what happens once you throw the trap away, and how much it will cost for you to get rid of the wasps completely since you may have to buy several disposable traps before your problem is over.
