Are There Mosquitoes In St Lucia? Bugs in St Lucia Guide

Wondering if there are mosquitoes in St Lucia?

Mosquitoes are super annoying and can even be dangerous so it’s always worth checking what you need to do before traveling somewhere new.

This ultimate guide to bugs in St Lucia covers the types of insects you’ll find in St Lucia and how you can protect yourself.

Are There Mosquitoes in St Lucia?

Yes, there are mosquitoes present in St Lucia so it is recommended that you wear insect repellent to prevent yourself from being bitten.

St Lucia is largely made up of a lush tropical rainforest with lots of standing water meaning it’s an ideal location for mosquitoes.

That being said, it also depends largely on where you stay. If you’re staying at one of the more fancy resorts like Sugar Beach or the Royalton then you have less to worry about.

These types of resorts will spray their entire grounds with bug spray so you won’t see many mosquitoes at all. 

Most resorts also have screens or mosquito nets to keep the bugs out of your room.

It’s still recommended that you wear insect repellent though as the odd mosquito will still show up.

If you’re heading out of your resort to explore the island then you’ll need to be more careful especially if you’ll be heading into the rainforest or on a hike.

The mosquitoes in St Lucia are particularly present at dawn, at dusk and after a rain shower so take particular care during these times.

To compare, the mosquito situation in St Lucia is similar to most other Caribbean islands.

St Lucia Mosquito Season

Mosquitoes are more prevalent in St Lucia at certain times of year.

The St Lucia mosquito season runs from June until November when levels of mosquitoes are higher and you’re more likely to be bitten.

This is also the rainy season so you will experience the odd rain shower from time to time which is what attracts the mosquitoes.

Mosquitoes breed in standing water so after a heavy rainshower, mosquitoes are attracted to the water puddles that remain where they then lay their eggs.

Mosquitoes in St Lucia are less prevalent between December and May which coincides with St Lucia’s dry season.

As there’s little rain during this time, there’s less free standing water for mosquitoes to breed in so the levels are much lower.

St Lucia Mosquito Borne Diseases

Although the majority of bug bites in St Lucia will just cause an annoying itchy rash, there is a small risk that they could cause a mosquito borne disease.

Malaria is not present in St Lucia so you don’t have to worry about it.

The main mosquito borne diseases present in St Lucia are dengue fever, chikungunya virus and zika virus.

Here’s what you need to know:

  • Dengue fever – can cause painful bone, joint and muscular pains as well as a flu-like fever, nausea and headaches. Most people recover within a week but it can cause serious illness.
  • Chikungunya virus – can cause joint pain, fever, a rash and a headache. Clears up after a few days for most people however some people may experience swollen and painful joints for weeks or even years afterwards (super rare).
  • Zika virus – Infection during pregnancy can lead to birth defects. Zika can cause a rash, itching, mild fever, a headache, muscle pains and joint pains. Most people will only experience mild symptoms.

❗️Important: If you’re pregnant then speak with your doctor before going to St Lucia. In general, it’s not recommended that pregnant people visit areas that have a risk of zika virus.

Are Bugs a Problem in St Lucia?

Bugs aren’t particularly a problem in St Lucia. Most people who visit don’t find that it really affects their trip.

Mosquitoes are your biggest concern but if you take some basic precautions (more on this later) then you shouldn’t have any issues.

If you wear a good insect repellent every day then you’ll likely not even notice the mosquitoes at all.

St Lucia Insects

As well as mosquitoes, other insects that are present in St Lucia include sand flies, moths, beetles, ants, flies and spiders.

You’ll likely see the odd insect here and there (as you will in any tropical location) however it’s definitely manageable.

Do You Need Mosquito Repellent in St Lucia?

Yes, you need to use mosquito repellent in St Lucia to prevent mosquito bites.

The best mosquito repellent for St Lucia is the Repel Sportsmen 40% DEET. This repellent is my holy grail as the bugs just don’t even come near you.

Bugs, like mosquitoes, can spread several diseases if they happen to bite you whilst you’re on vacation in St Lucia.

Whilst dangerous diseases, like dengue fever and zika virus, are rare, they can happen so it’s worth protecting yourself.

At a minimum you’ll be left with an itchy red bite so it’s worth preventing it if you can.

Here’s some tips on how to prevent bug bites in St Lucia:

  • Cover any exposed skin by wearing long-sleeved tops and long pants.
  • Use a good insect repellent (more on this below).
  • Sleep in an air-conditioned room or use a mosquito net.

You can also opt to stay at one of the fancier resorts which spray their grounds regularly with insect repellent to keep the bugs at bay. 

These fancy resorts also have air-conditioning in the rooms, screens to stop the bugs getting in and they will usually provide you with a mosquito net if necessary.

What Type of Insect Repellent Should I Use?

Always use an insect repellent that contains 20% or more DEET. The higher the percentage the better.

DEET is one of the most effective ingredients and is proven to prevent bug bites.

It works against both mosquitoes and ticks.

If you want something that will definitely keep the bugs away then try this bug repellent which contains 40% DEET. You’ll only need a small amount and the bugs won’t even touch you.

Also look for an insect repellent that is EPA-registered. This means that the spray is proven to be both safe and effective for everyone, including pregnant and breastfeeding women.

The insect repellent mentioned above (this one) is EPA-registered.

💡Tip: Always apply your insect repellent after your sunscreen and reapply throughout the day.

How to Deal with Bug Bites

If you do end up getting bitten, don’t worry. There’s a few things you should do:

  • Avoid scratching the bite. Even though it’s tempting, this will make it worse.
  • Apply a soothing cream like this one to reduce the itching. A hydrocortisone cream works best for this.
  • Monitor any symptoms. The vast majority of bug bites will not harm you but make sure you seek medical attention if you get any strange symptoms.

And that’s it!
