Which replacement bulb does my DynaTrap Mosquito Trap use?

We review products independently, but when you purchase through links on this page we may receive a small commission.

Even if you're a diehard fan DynaTrap mosquito and insect products, the only thing more confusing than all the current and past model numbers and variations is figuring out which replacement bulb(s) to buy! Even traps that are similar in exterior design may use a different bulb or bulbs.

The chart below shows what replacement bulb you need each model of DynaTrap mosquito or insect trap. Please double check the bulb specs and description before purchasing. If your trap isn't listed here, contact the manufacturer to verify the correct bulbs to buy.

How often should I replace my DynaTrap bulbs?

The manufacturer recommends replacing your bulbs after every 3,000 hours or approximately 4 months of use. The bulb in the DT1120 is an LED bulb - it will last much longer and may not need to be replaced for many seasons of use. We recommend keeping a spare bulb or spare set of bulbs on hand in case your bulb burns out unexpectedly.

Where can I buy DynaTrap replacement bulbs?

Most stores that carry the DynaTrap products also carry replacement bulbs, unfortunately many only carry the most popular ones. For easy online purchases, Amazon is a reliable choice with a wide selection. EBay can be a good resource for hard-to-find items and open box discounts.
