Real CO2 from propane combustion, rather than a chemistry-mimicked surface, is what sets the Patriot Plus apart among consumer traps, and it is why it kills meaningfully more biting insects than the DynaTrap in serious-infestation yards. Today's Homeowner and MosquitoReviews both report measurable population drops in 7-14 days and a steady-state reduction over the season. Price is the wedge: $506 MSRP plus $25-30/month in propane and octenol refills keeps it niche. On a 1-acre lot in Florida or the coastal South it is the only trap that consistently performs. Multi-season reliability is the recurring concern.

Strengths
  • Real CO2 emission (from propane combustion) catches 10x more mosquitoes per night than UV-only traps in heavy-infestation yards
  • 1-acre coverage with a 50-foot AC power cord allows positioning away from outlets
  • Silent operation no fan whir, no zap, no light pollution at night
Watch-outs
  • Propane tank ($15-20) plus octenol cartridge (~$12) every 21 days, roughly $25-30/month in refills
  • Reliability issues commonly reported after 1-2 seasons in Home Depot and Today's Homeowner reviews
  • $500+ upfront price puts it well above every other option in this lineup

The Thermacell E90 neither traps nor kills. It warms a metofluthrin-treated puck to raise a 20-foot vapor zone mosquitoes will not fly through, which makes it the fastest way to reclaim a patio for one evening. Family Handyman judged it more effective than bug zappers and longer in range than citronella candles. A 9-hour rechargeable battery covers a full evening and refills work out to roughly $1.50 a night. The catch is that it does nothing about your population problem, and a 5 mph breeze can hollow out the zone.

Strengths
  • 9-hour rechargeable lithium-ion battery covers most patio evenings on a single charge
  • 20-foot protection zone establishes in 5-15 minutes with no flame, no spray, and no scent
  • Refill pucks work out to roughly $1.50 per night of protection, cheaper than running a trap continuously
Watch-outs
  • Repellent zone collapses in wind above ~5 mph, per multiple reviewer reports
  • Does not kill mosquitoes or reduce the breeding population it just pushes them out of the protected zone
  • Refill puck must be replaced every 12 hours of use, adding ongoing cost

How they stack up

Mosquito Magnet Patriot Plus MM4200B

Catches roughly 10x more mosquitoes per night than the DynaTrap DT2000XLPSR in heavy-infestation yards because it emits actual CO2 from propane combustion rather than just titanium-dioxide mimicry. More expensive upfront and ongoing than every other option here, but the only one that targets breeding females specifically. Slower than the Thermacell E90 to deliver protection for an evening but unlike the E90, it actually reduces the population over weeks of operation.

Thermacell E90 Rechargeable Mosquito Repeller

Unlike the DynaTrap DT2000XLPSR or the Mosquito Magnet Patriot Plus, the E90 does not reduce the mosquito population — it pushes mosquitoes out of a 20-foot vapor zone for as long as it runs. That makes it the immediate-relief complement to the DynaTrap's slow population control rather than a substitute for it. Far quieter than the Flowtron BK-15D, and because it repels rather than electrocutes, far more pollinator-safe than any UV zapper, including the Katchy.
