What do you do when you find your pet food contains weevils? Weevils are a group of small beetles that feed on plants, especially grains. They can be found in any of common grains such as wheat, oats, rye and barley.
Their larvae are often found in packaged food, including dog and cat foods. Note that they don't make their way into sealed packages; they are already in the food as eggs. If your pet food is free of pesticides, chances are high that the weevils have laid eggs in the pet food.
Weevils can only survive in humidity over 55%, and it can take up to 6 months for them to hatch and turn to worms. Since both Singapore and Malaysia is a perfect environment for them to thrive and multiply, they will eventually hatch if you keep the pet foods for a long period of time without eating.
Weevils, whether in larvae or adult stage, are harmless and contain no diseases. They can be eaten along with any food they have infested without causing any harm.

How To Prevent Weevils In Dry Food
First and foremost, never buy pet food in bulk - just buy what you expect to use quickly. Do not allow the food to be exposed to air. Make sure the pet foods are in tightly sealed containers or stored in refrigerator or freezer. This is to ensure that the infestation is completely eliminated.
To avoid future problems with weevils, it is advisable to freeze your food. Freeze your pet food for at least 2 days or an entire week if you can’t keep in the fridge,. You can put your pet food in a freezer bag and in the freezer. The cold temperature will kill the eggs and they will never become weevils.
Meanwhile, fresh bay leaves work as a repellent. However, they don't kill weevils or keep the eggs from hatching.
If you don’t feel like freezing everything, you can kill the weevils with heat. Firstly, spread the food thinly on a baking sheet, preheat the oven to 120°F, and leave it in there for 1 hour. Otherwise, you can do 130°F for 30 minutes – a great option for those who are impatient. If you want to use the microwave, spread the food on a glass dish or plate, and run it for 5 minutes.
