How to Make a Homemade Wasp Trap

Wasps can be intimidating, especially if you’ve been stung before, but they play a crucial role in controlling other insects.

However, their attraction to sugary foods and proteins can make outdoor activities uncomfortable.

While commercial wasp traps are available, many people opt for homemade versions, which can be just as effective, if not more so.

Why Use a Homemade Wasp Trap?

Homemade wasp traps are simple, cost-effective, and can be made from common household items.

These traps work by luring wasps with sweet smells and trapping them inside, where they eventually drown.

Unlike chemical sprays or toxic baits, a DIY trap is a safer, non-toxic alternative that minimizes risk to your family and pets.

Making a homemade wasp trap is straightforward. You can use any household container, like a plastic bottle, and modify it into a trap.

Wasps are drawn to the bait, typically a sugary liquid, and once inside, they struggle to escape.

To increase the effectiveness of your trap:

Set it up early in spring: This is the time when female wasps (queens) are out and about. Each queen caught can prevent up to 1,000 worker wasps from appearing later in the season.

Keep the trap clean: Over time, dead wasps can accumulate, creating a surface for live wasps to “surf” on and escape. Regularly emptying the trap keeps it functional.

Do Homemade Wasp Traps Work?

The success of a homemade wasp trap depends on proper timing, placement, and maintenance.

Setting the trap early and cleaning it frequently ensures that it continues to capture wasps effectively.

While bright colors and fancy designs aren’t necessary, ensuring the bait is attractive to the wasps is key.

How to Make a Homemade Wasp Trap

To create an effective homemade wasp trap, you’ll need a plastic jug or bottle, preferably a large one, such as a liter soda bottle. Follow these steps:

1. Prepare the Bottle:

Cut off the top portion of the bottle, just below where it starts to widen.

Invert the top and place it back inside the bottle so that the spout points downward into the base. This forms a funnel that will trap the wasps inside once they enter.

2. Fill with Bait:

Pour a few inches (about 8 cm) of sugar water into the bottom of the bottle. The sugary liquid will attract the wasps.

If you find the opening is too wide, cover it with packing tape and punch a small hole just large enough for the wasps to enter.

3. Optional Enhancements:

You can dip the spout into honey or jam for extra attraction, but it’s not always necessary.

Additional Tips for Effective Wasp Traps

Prevent Honeybee Attraction: If you’re concerned about accidentally attracting honeybees, add a teaspoon (5 ml) of vinegar to the water. This helps deter bees while still attracting wasps.

Improve Effectiveness: Adding a few drops of dish soap to the water will reduce surface tension, preventing wasps from escaping by making it harder for them to gain traction on the water’s surface.

Adjusting for the Season: Early in the year, wasps are more interested in protein than sugar. To modify your trap for spring and early summer, use plain water and add some rotten meat. This will entice protein-seeking wasps during that part of the season.

By adjusting your bait and trap design based on the season and adding a few small tweaks, you can build an efficient wasp trap to manage these pests.
