Fleas can be a real pain, especially when they start infesting an area of your home. Thankfully, there are many ways to get rid of fleas. We spoke to pest control specialist Scott McCombe to bring you the best advice on how to make a flea trap. All you need to make your DIY trap is a shallow dish, some water, and a little bit of dish soap. With these tips, you’ll be saying goodbye to your flea problem!

Keep in mind that while flea traps are useful for killing fleas in a localized area, they have to be used in conjunction with other flea-control methods to be truly effective.

Making a DIY Flea Trap

  1. Fill a shallow dish or plastic lid with water.
  2. Pour 1 to 2 tablespoons (15 to 30 mL) of dish soap into the water.
  3. Mix the soap into the water.
  4. Place the trap where fleas have been spotted and leave overnight.
  5. Attract fleas to the trap with a lamp, small candle, or indoor plant.

Making a Dish Soap Trap

  1. Ideal containers for a dish soap flea trap include cookie sheets, rubber tote lids, plates, and pie plates. You want a container with a large surface area and short sides. [1]
    • A shallow dish helps you catch as many fleas as possible because the short sides won’t act as a barrier for jumping fleas that might land in the trap.
  2. Squirt 1 to 2 tablespoons (15 to 30 mL) of liquid dish soap into the water. Swish the water around with a spoon or your finger to distribute the soap throughout the water.
    • Fleas don’t drown in plain water because they aren't heavy enough to break the water’s surface tension. Adding liquid dish soap to the water reduces the surface tension. When the fleas jump into the trap, they sink and drown. [2]
    • McCombe also recommends adding some Alka Seltzer to the water to make the trap more effective. [3]

  3. A homemade flea trap doesn’t have the power to attract fleas, so it’s best to put it somewhere that fleas have already been in your house. Place a towel on the floor to catch spills, and lay the trap on top of the towel on the floor. Make multiple flea traps for different rooms if necessary. McCombe recommends placing the traps: [4]
    • On carpets and rugs.
    • Near pet bedding.
    • Near windows, doors, and food.
    • Around pillows and furniture.
    • Around pet bowls.
    • Near drapes and curtains.
  4. Fleas become active a couple of hours before sunset and stay active all night long, so the best time to catch them is overnight. [5] Once you lay the trap, try to leave it undisturbed for the rest of the night. When possible, close the door to the room to keep pets and kids out.
  5. In the morning, check the trap for dead fleas. If you catch any, dump the soapy water and rinse the dish. Fill the dish with fresh water, add more dish soap, and lay the trap out again on the towel for the next night. [6]
    • Repeat each night until you stop catching fleas.

Attracting Fleas to the Trap

  1. McCombe recommends placing a directional or table lamp beside the trap. Before bed, turn on the lamp and position the bulb above the trap so the light shines into it. As McCombe explains, the fleas will be attracted to the light and warmth, and when they jump toward the light, they’ll land in the trap below. [7]
    • Use an incandescent or other heat-producing bulb for your trap to attract the most fleas possible.
    • Make sure the lamp is sturdy and not at risk of being knocked over into the water. Use this attractant only in rooms where you can shut the door and keep people and pets out while the lamp is on.
  2. Fleas are, for some reason, twice as attracted to yellow-green light as they are to other colors of light. You can increase the efficacy of your lamp attractant by using a yellow-green bulb or by installing a yellow-green filter on a lamp with a regular bulb. [8]
  3. Use a tea light to create light and warmth to attract fleas to the trap. Place a tea light or votive candle at the center of the trap, and light the candle before bed. As the fleas try to get close to the source, they’ll fall into the trap and drown. [9]
    • Place the trap away from walls, drapery, and other flammable objects.
    • Always exercise great care and proper fire safety measures when burning candles.
    • Close off the room to prevent people and pets from entering when the candle is lit.
  4. Fleas are attracted to carbon dioxide, which is part of the mechanism they use to find a host. Because plants release carbon dioxide at night, placing one beside the trap may help to attract more fleas. [10]
    • Dormant flea pupae are particularly sensitive to carbon dioxide, so this may be a great way to catch young fleas before they have a chance to lay eggs. [11]

    Make sure your dog is on an anti-flea and tick medication. The best way to ensure your pet stays safe while outside is to give them protection from fleas and ticks. A flea and tick medication can help deter fleas and keep them out of your home.

  2. Adult fleas, eggs, larvae, and pupae can hide almost anywhere in your house, so you vacuum 3 to 4 times each week to stay on top of them. Use a strong vacuum that will suck fleas and eggs from the nooks and crannies in your house. [16] Use a brush or nozzle attachment for hard-to-reach areas.
    • Vacuum floors, carpets, sideboards, furniture, around windows, and especially around areas where your pet spends the most time.
    • McCombe advises discarding the contents of your vacuum in an outside trash can away from the house immediately.
  3. Fleas and eggs won’t survive a trip through the washing machine and dryer, so launder everything that can go into the washing machine and hand wash everything else. Use the hottest water and highest heat settings in the washer and dryer. [17] Items to wash include:
    • Blankets
    • Sheets
    • Pillowcases
    • Pillows
    • Shoes
    • Clothes
    • Pet toys
    • Pet bowls
    • Towels
  4. Flea infestations can persist for months if you're not successful at removing all the fleas and their eggs . For stubborn infestations, use a pyrethrin-based pesticide with an insect growth regulator, such as Ultracide or Onslaught . Apply the insecticide inside and outside.
    • Get everybody out of the house. Put on gloves, goggles, long sleeves, and a respirator to apply the insecticide. Use a dust or aerosol product and apply a light mist on floors, walls, furniture, and all other surfaces inside the house. Allow the dust or spray to settle before letting people back in. Vacuum after 48 hours.
    • Outside, apply a layer of dust or spray to the garden, on bushes and shrubs, around tall grass, in wooded areas, and around windows and doors.

I'm mortified to be here asking this but I'm desperate at this point: I have fleas in my house and I dont' know how to get rid of them. They seem to really like my dog (mostly indoor dog but we use flea and tick meds) and the couch. I wouldn't say it's an infestation just yet, but it's been like this for months and nothing I do is keeping them away! What should I do/what am I doing wrong?

I highly recommend taking your pet to the vet if you suspect fleas in the home. That's always the first step. The next step is to wash all of the pet's bedding and make sure you're using high heat for at least an hour on a dry cycle to get rid of any eggs or larva that might still be in there. Vacuum your home frequently, as well.

Make sure you're using the right flea medication for your dog's breed and size first to kill all live fleas and eggs. Then, use a flea comb to remove the fleas and eggs from their fur. If you don't do the treatment first, the flea just jumps off the comb and lands somewhere else, so combing alone won't be effective.

      Article Summary X

      To make a flea trap, begin by filling a shallow dish with water, then stirring in 1 tablespoon of dish soap. Next, put the dish in a place where you’ve seen fleas and let it sit overnight. In the morning, empty the dish with the dead fleas and refill it with more soapy water. Then, repeat this process until the fleas are gone. If the dish isn’t attracting enough of the fleas, try placing it under a lamp or near a candle, since fleas will be drawn to the warmth and light. For tips on keeping fleas out of your house in the first place, read on!
