What to Know to Stay Safe

Written by Tamarindo News

As a tropical country, mosquitoes in Costa Rica are present year round. Here is what you need to know about mosquitoes in Costa Rica and we included a list of our recommended mosquito repellent. Living somewhere that has mosquitoes year round, we test and use a lot of repellent!

Mosquito Borne Diseases: Dengue, Malaria, Chikungunya and Zika in Costa Rica

When it comes down to diseases from mosquitoes in Costa Rica, dengue is the one to be concerned about.

Dengue: Dengue is a big concern in Costa Rica. In 2020, Costa Rica had 9438 documented cases of dengue. There are 4 different types of this viral disease and is treatable for acute or mild cases. It is not very common for people to die of dengue although it can happen.

Malaria: Malaria is not common in Costa Rica. Costa Rica has done a great job eradicating malaria in the country with 8 cases in 2012, 108 in 2018 and and 11 in 2020. They’ve reduced malaria over 90% since 2000. Although your travel doctor may recommend to take malaria medication, with the near eradication of malaria in Costa Rica, it is not necessary.

Chikungunya virus: Also present in Costa Rica and doesn’t have a vaccine or cure. It was found for the first time in the Americas in 2013, before it was only in Africa, Asia and Europe. Chikungunya is not that common in Costa Rica with only 49 cases in 2020.

Zika: Zika has been around since the 1950’s mostly in Asia and Africa but has been showing up in North America the past couple years. Costa Rica had only 121 cases of Zika in 2020.

Which Areas Have the Worst Mosquitoes in Costa Rica?

Although there are mosquitoes year round, mosquitoes are generally not found in higher elevations in Costa Rica, around 1600 meters and up (5249 feet). They are prolific on the coasts, beaches and low elevation areas.

There are mosquitoes in Tamarindo, Playas del Coco, Samara, Puerto Viejo, Tortuguero, Jaco, Osa Peninsula, Uvita, Manuel Antonio, Santa Teresa, aka everywhere on the coasts. Likewise, there are mosquitoes in La Fortuna, Sarapiqui, and the lower elevation rainforests.

However, there aren’t really mosquitoes in higher elevation places such as Monteverde, Vara Blanca and Poasito as that’s about 1500 meters and above.

Mosquitoes also like swimming pools so be careful when you’re laying out at your hotel pool. They are relentless!

Additionally, sunset time (5-6 PM) on the beach is happy hour for sand gnats/flies and they bite hard so be aware of them.

Worst Time of Year for Mosquitoes in Costa Rica

Mosquitoes are present all year long in Costa Rica. However, since mosquitoes breed in stagnant water, rainy season (May to end of November) is the worst time of year for mosquitoes.

Unfortunately streets in Costa Rica do not have good drainage and when it rains, drains get clogged. Huge pools of water stay on the streets for days allowing mosquitoes to breed prolifically. For these reasons, you will need to bring or buy plenty of mosquito repellent for your trip to Costa Rica.

The Best Protection Against Mosquitoes

The best protection against mosquitoes in Costa Rica is to wear long sleeves and pants and to cover up. That is the only surefire protection against mosquitoes.

However, it’s not ideal to be wearing long sleeves and pants in 90 F tropical heat and humidity. So then you will need to apply mosquito repellent.

Best Insect Repellent Against Mosquitoes in Costa Rica

Here are the best products we tried ourselves. We recommend bringing mosquito repellent for your trip because it is more expensive in Costa Rica. Additionally, there aren’t a ton of options if you prefer natural products.

Remember, what works for me may not work for you 100% and I am a mosquito magnet. I try to use non-DEET products as much as possible but honestly for me, DEET works the best compared to other products.

Spray

I particular love a brand called Jungle Juice that is available at REI or this brand, Repel 100. It’s a little bottle but you don’t need much and it’s the perfect travel size. Whenever we go to the national parks or into the jungle for hiking, we always use this one and we don’t get bit at all.

Another one we like is Ben’s Max. This one contains around 30% DEET and works great. I could see the bugs hovering over my arm but never got bit!

For sprays, I need at least 30% DEET. Any less and I will still get bit.

Natural spray

For those who don’t want to use DEET, the Repel Natural is one of my favorite DEET free products but I do need to reapply about every half an hour or so.

I recently found another one called Bull Frog Mosquito Coast that doesn’t use DEET and also has sunscreen. This one surprisingly does work very well for me.

I do need to reapply every couple hours but for a non-DEET product, this one is my favorite.

Mosquito Repellent Wipes

Mosquito wipes are great for those who don’t like to use sprays. It is also very convenient to carry as they weigh practically nothing and aren’t considered a liquid (better for those traveling with a carry on). These are 30% DEET and lasts up to 10 hours.

We used these on our legs and arms and they worked well for us. I prefer using the wipes when we’re hiking as they are super light.

Insect Repelling Bands

These insect bands don’t contain DEET this is another natural product. It contains Geraniol, a plant based material that repels mosquitoes.

These bands are for your wrists and feet and you can just leave it on. They are water friendly and supposedly works up to 120 hours.

We put the bands on our ankles to test out how well it worked without any other product. It didn’t work for me at all, I got bit the first hour I had the bands on so I personally won’t be buying these again.

Mosquito Repellent Lotion

This mosquito lotion is applied with a sponge. It’s good up to 12 hours (time release) with 33% DEET and it worked great for us.

The lotion is heavy though so you definitely feel like you’re wearing it. It isn’t as quick as putting on a spray but you can make sure that you got all exposed areas covered with the sponge.

When it comes down to it, I prefer the spray since it’s faster and lighter but the lotion does make you feel like you’re really covered.

Mosquito repellent clothing

Quite a few outdoor sports brands have developed an insect repellent technology for clothing.

Columbia is one of them and we have one of their bug shield shirts which we love.

If you plan to hike in the rainforest, this is the best protection against mosquitoes in Costa Rica. Then make sure to apply repellent for any areas that are exposed.

Since there are several brands, it’s good to read reviews since they can be expensive. We love our Columbia shirts!

DEET Alternative

We tried a DEET alternative spray called Avon Skin so soft. It contains Picaridin which is still a synthetic chemical compound. I recently discovered this and it’s much more pleasant smelling than DEET. It also works decently for me!

Another excellent insect repellent that doesn’t use DEET (it has 20% Picaridin, a non toxic ingredient) is Proven Insect Repellent.

Afterbite Itch Eraser

If you do get bit, you’ll want to put something on those bites especially if they swell.

The After bite eraser also works well and we found that it took away the itchiness pretty fast. You just dab a little bit on and let it do it’s magic.

Purchasing Mosquito Repellent in Costa Rica

If you have to buy mosquito repellent in Costa Rica, you can find them in all supermarkets. Some supermarkets like Maxi Pali or Mega Super may only have a few options with only DEET. If you go to a supermarket like Auto Mercado or Vindi, they usually do have a natural option or two.

Another way to get non-DEET mosquito repellent is to go to a macrobiotica or organic store in Costa Rica. Sometimes they will have more natural products. Additionally, there may be some vendors at the farmer’s markets that have natural mosquito repellent. The Tamarindo night market and farmer’s market usually has vendors that sell organic natural items including repellent.
