How to Inspect for Small Brown Bugs in the House

To check for small brown bugs in house:

  1. Start by taking a stroll through the rooms and other areas of your house to check for any signs of an infestation. Pay particular attention to the kitchen and pantry, as well as other areas where food is cooked or stored. Look for signs of damage, such as holes in food packaging, and live bugs
  2. Next, check out frequently ignored regions like the attic, crawl spaces, and basements. These places may act as a haven for little brown bugs and the origin of an infestation. Look for droppings or exoskeletons, as well as any entryways, such as cracks in screens or walls.
  3. Then, look for other entryways. Examine the windows and doors and the space around them for gaps or cracks in the walls or foundation.
  4. Inspect food items in your storage for little brown bugs. You should look for tiny holes or a musty odor.
  5. Dispose of infested food right away.

By routinely checking your home for signs of an infestation, you can control these small pests before they become a big problem.

Use weatherstripping, door sweeps, window, and door screens to keep the bugs out too.
  • Reduce moisture levels in the house: to make your home less attractive to pests, fix any plumbing or roof leaks, use a dehumidifier, properly ventilate moist environments like the bathroom or laundry room, and get rid of standing water in sinks or tubs.
  • Have a cleaning routine: keep food preparation and storage areas by vacuuming, wiping up spills, and cleaning up crumbs or food scraps.
  • Essential oils: use peppermint, citrus, or eucalyptus oil in water to make a repellent spray, or use a diffuser. You can also make carpet powder by adding a few drops of essential oil into baking powder and vacuuming it after application.
  • Other natural repellents: you can use put bay leaves and cloves in your pantry to protect the area from bugs.
  • Diatomaceous earth: use diatomaceous earth around windows and doors as well as other areas where you've seen the bugs out and about or use food-grade diatomaceous earth in cereal, wheat, pasta, and other food items to stop an infestation.
  • Traps: you can buy sticky or pheromone traps to capture bugs as well.

Chemical Remedies

Despite the fact that natural solutions can help with a pest infestation, there are instances where chemical products are needed to get rid of bugs once and for all. You can use insecticide, pesticide, herbicide, or bait traps to lure insects in, trap them, and poison them. The most effective chemicals that you should look for when dealing with small brown bugs in house include:

  • Permethrin: This insecticide overstimulates an insect's nervous system, which results in paralysis and death.
  • Pyrethrin: this is another neurotoxin that can kill insects on contact or when ingested

To protect yourself, your family, and the environment from potential harm, it's crucial to apply pesticides responsibly:

  • Choose a pesticide, insecticide, or herbicide that's specially formulated for the species you're trying to kill and only in the recommended dosage.
  • Wear protective clothing, gloves, goggles, and a mask when applying chemical products to prevent contact with the skin and eyes.
  • Avoid using chemicals near food preparation, storage, or consumption areas.
  • Keep the area well-ventilated before and after using a chemical product.
  • Keep chemicals away from pets and children. They should be kept in high, out-of-reach areas or in a locked cabinet.

For both natural and chemical treatments, you can reach out to a pest control specialist at any time for advice or assistance.
