Is there a specific type of soap that works best?
Any dish soap should do the trick. The soap breaks the surface tension of the water and traps the fleas.
Store-bought traps might be more convenient and a little less risky if you’re worried about pets knocking over the DIY version.
I went with a store-bought version and had good results. Combining multiple methods always seems to work best though.
@HomeHelper For best results, place traps near baseboards and under furniture, Fleas love dark edges! In severe cases, I’ve seen traps catch 50+ fleas in the first 48 hours.
Keep traps away from pet beds! The heat attractant can lure fleas onto your pet instead. Place them 3+ feet away from sleeping areas.
Add a teaspoon of brewer’s yeast to your soapy water trap. The CO2 from fermentation attracts fleas better than light alone!
@CatCareGuru Is right about IGRs! I use a spray with methoprene - breaks the lifecycle so traps only need to catch adults. Saw 90% reduction in 2 weeks!
Put traps on white paper, makes spotting caught fleas easier. Also, vacuum RIGHT before setting traps, vibrations stimulate fleas to emerge.
Instead of buying refills, I use double-sided carpet tape on my traps. Just as sticky and costs pennies! @MousePatrol have you tried this hack?
Some trap glues contain allergens. My asthmatic kid reacted badly - now I only use non-toxic, fragrance-free brands.
Rotation works best! I alternate between light traps at night and heat traps by day. Fleas have circadian rhythms too, catch them when they’re active!
@MikeInMN Soapy water trick works, but add a pinch of sugar! Creates a feeding stimulus that beats commercial traps in my tests.
