Rice weevils are small beetles that feed on rice and other stored grains, and are identified by their reddish-brown coloration and four reddish-yellow spots on their wings.

These pests lay their eggs inside the grains, and the larvae feed on the inside of the grain, leading to significant losses in stored grain if an infestation occurs. Rice weevils can infest any type of grain, including wheat, oats, barley, corn, and rice.

In order to prevent an infestation, grain should be stored in sealed containers, at temperatures below 80 degrees Fahrenheit and in a dry area.

Inspecting grain regularly for signs of infestation, including tiny holes in the grain, webbing, or adult weevils is also important.

If an infestation is found, the contaminated grain should be discarded and measures should be taken to control the population.

Rice weevils can cause significant damage to stored grains, and it is important to be aware of the signs of an infestation and take preventative action to control them.

Taking the proper precautions to store grain can help to reduce the risk of an infestation and protect your stored grain.
