There are a lot of things you can do with used and unused coffee grounds around your home and garden, but do coffee grounds attract pests? When it comes to pest control, you want to make sure you’re not doing anything to attract unwanted pests. Fresh coffee grounds have some really neat uses, and you’ve probably been told a coffee ground hack or two to try for plant growth, skin health, and even odor neutralizing. If you’re wondering if you can add pest control to your list of uses for ground coffee, keep reading.

Do Coffee Grounds Attract Pests?

The use of coffee grounds does not attract pests. In fact, it’s a great repellent of all types of pests, from pesky insects to rodents. Just the smell of coffee grounds is all it takes to deter insects like adult mosquitoes, bees, fungus gnats, wasps, ants, slugs, cockroaches, and more. Not only will coffee grounds repel insects, but they also repel rodents like rats and mice. 

So what do these pests dislike about coffee? The grounds contain caffeine and a strong odor, both of which act as natural repellents for insects and rodents. The caffeine is a natural stimulant that can disrupt the nervous systems of insects and rodents, and the strong odor is unpleasant to them, and they will avoid it entirely most of the time. 

What they seem to dislike even more than coffee grounds is burnt coffee grounds. This seems to be the most effective way to use coffee grounds as a natural repellent. All you have to do is lay coffee grounds out on a plate or bowl and burn them like incense. But the effectiveness of coffee grounds seems to be widely used by gardeners and they typically don’t burn their coffee grounds, so either way should work pretty well as a natural pest repellent. 

How to Use Coffee Grounds to Repel Pests in Your Garden

If you’re a home gardener and you want to keep your pest control organic, coffee grounds may be the best way to go. Using coffee grounds to repel pests in your garden is cheap, easy, and all natural.

1. Spread coffee grounds on top of your soil. 

Sprinkle coffee grounds in a thick layer on top of your soil and around your plants. Make sure to cover the entire area of your garden bed. Coffee grounds will act as a barrier to keep out pests. 

2. Add coffee grounds to your compost. 

Adding coffee grounds to your compost pile will help deter pests from entering your garden. 

3. Make a coffee spray. 

To create a coffee spray, steep two cups of coffee grounds in a quart of boiling water, let it sit for 24 hours. Strain the mixture and pour it into a spray bottle. You can then spray the mixture around your garden to repel pests. 

How to Use Coffee Grounds to Repel Pests Around Your Home

The strong aroma of coffee grounds can act as a deterrent to many insects and rodents who may be bothering you around your outdoor sitting areas or are interested in getting into your home.

1. Make a perimeter with coffee grounds surrounding your house.

Keep pests from crossing through cracks, doorways, and windows by laying a thick perimeter of coffee grounds all the way around your house. You’ll need to replace the coffee grounds on a regular basis with fresh coffee to keep the scent strong. 

2. Burn coffee grounds like incense in your outdoor areas.

This is helpful for keeping mosquitoes away from your outdoor seating areas. Let a bowl of coffee grounds dry out in the sun, then burn them like incense. The smoke will repel mosquitoes while you’re enjoying your outdoor areas. Then you can use the burned coffee grounds for other practical uses like in your potted plants or gardens to repel even more insects for better results than the unburned coffee grounds. 

Where to Get Coffee Grounds for Pest Control

If you’re a coffee drinker, you probably have an endless supply of coffee grounds coming out of your coffee machine each day. Even better if you use a french press, which produces a much stronger scent than a regular coffee maker. Dry out your used coffee grounds and save them in a glass jar or other container with a lid to keep the fresh, strong smell so they stay potent until you’re ready to use them.

If you’re not a coffee drinker and you’d like to use this easy way to deter pests, the good news is you still have options. You can always ask a friend for their coffee grounds or visit a local coffee shop and ask them if they would be willing to save their coffee grounds for you every once in a while. The type of coffee used doesn’t matter, so any used coffee grounds they can give you will be helpful. 

Can Coffee Grounds Get Rid of a Pest Infestation?

While coffee grounds can be an effective deterrent for many types of pests, if you’re dealing with an infestation of pests in your garden, yard, or your home you’ll probably need a solution that is more aggressive than a DIY rodent or insect repellent made from organic materials. Coffee grounds won’t take care of issues like mosquito larvae or actually killing off a large population of pests.

After your infestation is taken care of by pest management professionals, using old coffee grounds can be a great addition to your preventative measures and a good idea to help avoid another infestation.
