Roaches are one of the most stubborn and peskiest pests to deal with. Once they infest a home, they can be difficult to fully get rid of. Many commercial roach sprays and traps contain harsh chemicals. These work, but expose residents (and pets) to toxins. Thankfully, there are many natural ways to repel roaches that are safe and effective. This guide covers scientifically-backed methods for repelling roaches without using chemicals.

Block Entry Points

Roaches need food, water and shelter to survive. Limit their access by sealing any possible entry points:

• Cracks around windows, doors, pipes, vents, etc. Seal with caulk or foam sealant. Copper mesh can also be stuffed into cracks.

• Holes in screens. Patch any tears.

• Gaps around plumbing. Seal gaps around pipes under sinks and appliances with silicone caulk.

• Pay special attention to entry points between the kitchen and bathroom. Cockroaches love warm, moist areas with access to food and water.

Clean Effectively

While roaches can survive on tiny scraps of food, keeping things clean will limit their food sources:

• Sweep and mop floors daily. Pay attention to hard-to-reach areas behind appliances and under furniture.

• Vacuum carpets and furniture regularly. Vacuuming removes eggs and food residue.

• Empty garbage frequently. Don't let it overflow. Use bags or cans with tight lids.

• Clean dirty dishes and wipe down countertops immediately after meals. Don't leave food or spills overnight.

• Keep the kitchen and bathroom as dry as possible. Roaches need water to survive.

Use Natural Repellents

Certain natural scents deter roaches or disrupt their reproduction:

• Essential oils: Oils like peppermint, tea tree, bay leaf and clove oil repel roaches. Spray a mix of 10-15 drops of oil per cup of water in problem areas. Reapply after cleaning.

• Diatomaceous earth: The powdered fossilized remains of algae has sharp edges that damages the waxy coating on roaches’ exoskeletons, causing dehydration. Apply a fine dusting in crevices and hidden areas. Wear a mask when spreading.

• Boric acid: This mild acid disrupts roaches' metabolism when ingested. Sprinkle a fine layer in out-of-reach areas and entry points. Avoid using around pets.

Maintain a Dry Environment

Moisture sources attract roaches looking for water. Eliminate damp areas where possible:

• Fix any plumbing leaks like dripping faucets or pipes.

• Use dehumidifiers and fans to circulate air, especially in humid rooms like bathrooms.

• Make sure AC units drain properly and aren't leaking condensation.

• Avoid leaving standing water around sinks and tubs.

Use Traps as Monitoring Tools

While natural repellents deter roaches, traps help monitor any lingering activity:

• Sticky glue traps capture roaches that walk over them. Place along walls or in secluded areas. Check often and replace frequently.

• Bait traps use food roaches can't resist to lure them in. Look for traps with boric acid or diatomaceous earth instead of chemical pesticides.

• Track activity to pinpoint any additional problem areas that need addressing.

When to Call an Exterminator

If roach activity doesn't decrease significantly after thoroughly trying these methods, it may be time to call a pest control professional. They have access to stronger chemical treatments and can target nests and infestations in hard-to-reach areas.
