Trap Care

At the height of mosquito season, a trap needs regular attention to ensure that its bug-catching ability doesn't flag.
AS NEEDED: Empty the net, cup, or tray, or replace adhesive pad (four for $20 at home centers).
EVERY THREE WEEKS (approx. 500 hours): Replace octenol cartridge or scent strip (three for $20).
MONTHLY (approx. 700 hours): Refill the CO2 supply. Your first propane tank will cost about $45; swap the empty for a full one for around $20. Your first CO2 canister, available from a gas supplier, will run about $120; refills cost about $20 apiece.
