The weevil needs to have access to whole seeds in order to reproduce. This means that bulk whole-grain products are a key factor in their reproduction process. Bags or boxes of grain products will often be the first place that you see that weevils have moved in. The weevil is brown in color and can be seen scuttling around inside grain products or might be visible when the item is poured out for use in cooking.

Unsealed food is just asking to become a haven for weevils. You will need to throw away infested food and also unsealed food that you cannot keep weevils from gaining access to.

Apply heat or cold to stored foods

Weevils cannot handle cold or heat, so you can protect the food that has not been contaminated by freezing it or putting it somewhere hot. Not all food products can handle these temperatures, but if you have items that can be placed in the freezer or heated for a short time, you might be able to protect them from becoming a new haven for infestation.

Can weevils get into your bedroom?

Weevils might get into any room in your home, but they are most likely to be drawn to areas where there is a food source to be had.

Will weevils spread around my home?

Weevils are not prone to spread all over the home because there is not enough food in the rest of your house to sustain them. They will naturally be drawn to the kitchen or any other area that has whole-grain food items on offer. If you have weevils in other parts of your home, you need to go looking for the food source that is drawing them there. You might have some spilled food or stored food hiding in a closet or cabinet that are bringing them into other parts of the house.

Do weevils come out at night?

This means that you might not realize that you have weevils in your home until late in the day, when they start to move around enough to be noticeable. Weevils are definitely hard to spot in the garden or your yard until night has fallen due to this preference.
