As the warmer months approach, spending time outdoors becomes more appealing, but with the outdoors come mosquitoes. DEET, one of the most effective ingredients in mosquito repellents, is a go-to solution for keeping these pesky insects at bay. However, while DEET is highly effective in repelling mosquitoes, it can also pose a threat to our beloved plastic drinkware. Here’s what you need to know to keep your drinkware in top condition.

What is DEET?

DEET, short for N,N-Diethyl-meta-toluamide, is a powerful chemical used in many insect repellents. Developed by the U.S. Army in 1946, DEET has become the gold standard for repelling mosquitoes, ticks, and other biting insects. It works by confusing the insects' sense of smell, making it difficult for them to detect and land on humans. While it’s incredibly effective in protecting us from insect bites, DEET can have some unintended side effects, particularly when it comes into contact with certain plastics.

Why DEET Affects Plastic Drinkware

DEET is a solvent, which means it can break down certain materials, including plastics. When DEET comes into contact with plastic drinkware, it can cause the material to become sticky, discoloured, or even warped. This is because the chemicals in DEET can dissolve or weaken the polymers that make up plastic, leading to damage that can ruin your favourite drinkware. This is particularly important to keep in mind when using plastic cups, glasses, or bottles during outdoor activities where mosquito repellent is being used.

Tips for Using Plastic Drinkware Around DEET

1. Keep DEET Away from Drinkware: When applying mosquito repellent, be mindful of where you spray it. Try to avoid spraying DEET directly onto or near your plastic drinkware to prevent accidental contact.

2. Wash Hands After Applying DEET: After applying DEET to your skin, wash your hands thoroughly before handling any plastic drinkware. This will help minimise the risk of transferring the repellent to your cups or bottles.

3. Use Protective Barriers: Consider using coasters, placemats, or other barriers to keep your drinkware from coming into direct contact with surfaces where DEET might have been sprayed.

4. Opt for DEET-Free Alternatives: If possible, use DEET-free mosquito repellents when planning to use plastic drinkware. There are many effective alternatives on the market that are less likely to damage plastic materials.

5. Inspect Drinkware Regularly: If you suspect your plastic drinkware has come into contact with DEET, inspect it for any signs of damage. Replace any items that appear sticky, discoloured, or warped to ensure safe use.

DEET is a powerful ally in the fight against mosquitoes, but it’s important to be cautious when using it around your plastic drinkware. By following these tips, you can enjoy your outdoor gatherings without compromising the quality of your drinkware.
