It's frustrating to lift your trash bin lid and find wasps starting to build a nest inside. Not only is it unpleasant, but it can also be a safety hazard. The good news is that you can prevent this with some simple, proactive steps.
First, understand the attraction. The enclosed space of a bin lid offers protection from the elements and predators, making it a prime real estate for wasps. To make it less appealing, you need to disrupt this sense of security.
Regular Cleaning is Key
The most effective method is routine cleaning. Wasps are drawn to food residues and sugary liquids. Every two weeks, or more often in peak summer, give your bin a thorough cleaning.
* Empty the bin completely.
* Scrub the interior and the underside of the lid with a mixture of hot water and dish soap or a mild disinfectant.
* A solution of equal parts white vinegar and water also works well, as the smell deters wasps.
* Rinse thoroughly and let the bin dry completely before putting a new bag inside. A dry, clean bin is far less attractive.
Use Natural Repellents
Wasps dislike certain strong scents. You can use this to your advantage by placing natural repellents in and around the bin.
* Essential Oils: Soak cotton balls in peppermint, lemongrass, or clove oil and place them in a small, open container inside the bin or attach them to the underside of the lid. Reapply the oil every week.
* Herbs: Place bundles of fresh or dried mint, thyme, or eucalyptus near the bin or inside the lid.
Create a Physical Barrier
If wasps are persistent, block their access.
* Petroleum Jelly: Smear a thin layer of petroleum jelly around the rim of the bin and the inner lip of the lid. This slippery surface makes it difficult for wasps to land and start construction.
* Hang a Fake Nest: Wasps are territorial and will not build a nest near another colony. You can purchase a realistic-looking fake wasp nest or make one from a brown paper bag and hang it near your trash bins. This is a passive and surprisingly effective deterrent.
Maintain Good Trash Habits
* Secure Lids: Always ensure the bin lid is closed tightly. A loose lid is an open invitation.
* Rinse Recyclables: Quickly rinse out soda cans, beer bottles, and food containers before tossing them in the recycling bin.
* Use Tightly Sealed Bags: Make sure all garbage is in sealed bags to minimize odors and leaks.
What to Do If You Find a Nest
If you discover a small, starter nest, do not swat at it. The best course of action is to carefully clean it away during the cooler evening or early morning when wasps are less active. Wear protective clothing. For larger, established nests, it is safest to contact a professional pest control service.
By incorporating these simple habits—regular cleaning, using natural scents, and maintaining your bins—you can effectively discourage wasps from turning your trash bin lid into their new home.
