Let me start by saying this post isn’t meant to drum up any fear — seems like every year a big publication will run a headline about mosquitoes and West Nile Virus on Long Island, but it’s always been around. I don’t want to make light of it either, but I mostly know how frustrating it can be when you’re outside trying to enjoy your evening, and the mosquitoes just won’t let up.
It’s a shame when we build people their perfect porch, but they feel like they can’t fully enaenoy it because of the hoops they have to jump through to combat these pests.
Before I get into all the tools, tech, and things you can do to keep mosquitoes off your porch, let’s talk about why they love it in the first place.
Why Mosquitoes Love Your Porch
These pests are drawn to a few things. They love carbon dioxide, body heat, and certain scents. Your porch serves it all up. Bon appétit (for the mosquitoes)! Standing water nearby from planters, gutters, or outdoor furniture is a big attractor, too.
Here on Long Island, our humid summers create ideal breeding conditions. Add in some shade, and it’s an environment and climate they love. I’ve seen homeowners unknowingly exacerbate the problem by leaving water in plant saucers or failing to clean their gutters on a regular basis.
The most effective approach combines the elimination of breeding sites with the use of active repellent products. You’ve got to tackle the issue from all sides. To get a good game plan in place, you need to think through some of the following:
- Porch size and layout – A small enclosed porch needs different solutions than a sprawling open deck
- Power access – Do you have an electrical outlet nearby?
- Family considerations – Do you have kids or pets that limit certain product types?
- Budget and maintenance – Some solutions require ongoing costs for refills or replacements
- More intense options – Areas near water or heavy vegetation need more aggressive approaches
Whenever possible, start by modifying your habitat first. First, remove standing water, trim back vegetation, and ensure good air circulation. Then layer on the active repelling products.
The Best Mosquito-Repelling Products for Your Porch
Here are the products I’ve seen work best for Long Island homeowners. These aren’t ranked in any particular order, but I’ve noted what situations each works best for:
Thermacell Patio Shield Mosquito Repeller
This is my go-to recommendation for most homeowners. The Thermacell creates a 15-foot zone of protection to keep mosquitoes back. It uses heat to activate repellent mats. It’s scent-free. It’s silent.
The device runs on butane cartridges that last about 12 hours, and the repellent mats need replacing every 4 hours. It’s not the cheapest option, but the convenience and effectiveness make it worth it for regular porch users.
One downside is that it takes about 15 minutes to get to its peak performance, so you need to plan to make sure it’s repelling all the mosquitoes before you go outside.
Dynatrap DT1050-TUN Insect Trap
It’s one of the most expensive mosquito-repellent tools you can buy, but it’s going to really help you take these pests head-on. If you have a serious mosquito issue, then this is a great option. It uses UV light, CO2, and a fan to attract and trap mosquitoes without chemicals or scents.
The unit covers up to half an acre, which is overkill for most porches, but that just means it’s thorough. It plugs into standard outlets and runs quietly enough that you’ll forget it’s there.
The main drawback is that it needs to run continuously to be most effective. You’ll also need to empty the trap regularly during peak mosquito season.
Cutter Backyard Bug Control Spray Concentrate
Sometimes the simplest solutions work best. This barrier spray creates a protective zone around your porch that lasts up to 12 weeks. I recommend it for homeowners who want a low-maintenance option that doesn’t require frequent repeat purchases.
You mix the concentrate with water and spray it on plants, porch railings, and surrounding areas. It’s good to have in your arsenal, but it may not be as effective as you want on its own. But if you pair it with another tool from this list, you’re going to be in good shape.
The spray has a slight odor when first applied, and you should be cautious around flowering plants because it could harm beneficial insects you may want to keep around.
Bug-A-Salt
Okay, this one’s more for entertainment than serious mosquito control, but I had to include it. The Bug-A-Salt shoots ordinary table salt to take down flying insects. It’s surprisingly effective and definitely fun to use.
It won’t solve a serious mosquito problem, but it’s a fun way to take down one or two.
Flowtron BK-40D Electronic Insect Killer
Bug zappers still have their place. Modern versions like the Flowtron are effective and durable.
This unit covers up to one acre and features a weatherproof construction that holds up well to Long Island’s variable weather. The distinctive zapping sound lets you know it’s working, though some people find this annoying during quiet evening conversations.
Position it away from your main seating area. You don’t want to invite mosquitoes to make a pit stop on their way to the Flowtron.
Repel Plant-Based Lemon Eucalyptus Insect Repellent
I get wanting more natural solutions. Repel isn’t the only brand to use the oil of lemon eucalyptus to combat mosquitoes, but they are one of the most-trusted brands.
It’s an effective protection comparable to low-concentration DEET products. Keep some on hand for personal application during evenings where the mosquitoes are relentless.
The scent is pleasant and not overpowering, making it suitable for use during outdoor dining. You will need to reapply.
Murphy’s Naturals Mosquito Repellent Candles
These aren’t your typical citronella candles. Murphy’s uses a blend of essential oils, including rosemary, peppermint, and cedarwood, that works. I’ve used them during outdoor dinner parties with good results.
Each candle burns for about 30 hours and covers roughly 12 feet. The scent is pleasant — not overwhelming — and they look nice as table decoration too. They work best in low-wind conditions, and you’ll need multiple candles for larger spaces.
Quick Summary
Keeping mosquitoes at bay isn’t easy. But if you follow these tips and adopt some of these repellents, you’ll be able to enjoy your time outdoors.
Many homeowners achieve excellent results with a Thermacell for immediate protection, combined with a barrier spray for longer-lasting perimeter defense. For those with a big mosquito problem, adding a trap like the Dynatrap provides continuous population reduction. Natural options are suitable for those seeking to avoid chemicals, although they often require more frequent application or replacement.
