Electric bug zappers, which work by attracting insects to light, are a very effective means of ridding an area of flying insects. Despite this, most pest control experts now advise against their use, recommending instead such remedies as insect-eating birds or insecticide sprays.

"Surprising" Phenomenon
Why do experts recommend other pest-control methods when bug zappers are very effective?

Objective
A hypothesis resolving this discrepancy will give a reason for pest control experts to prefer birds and insecticides over bug zappers. It will give a reason to avoid bug zappers despite their general effectiveness, or imply that insect-eating birds and insecticides are even more effective.

A
Insect-eating birds will take up residence in any insect-rich area if they are provided with nesting boxes, food, and water.
This does not explain why experts recommend insect-eating birds over bug zappers. It explains why the birds are effective pest-control measures, but makes no comparison with bug zappers.
B
Bug zappers are less effective against mosquitoes, which are among the more harmful insects, than they are against other harmful insects.
This does not provide a reason to favor insect-eating birds and insecticides because it takes no position on the effectiveness of those measures against mosquitos. It is possible birds and insecticides are equally or even less effective against mosquitos.
C
Bug zappers use more electricity but provide less light than do most standard outdoor light sources.
This does not explain why experts would avoid recommending bug zappers as a form of pest control. There is no evidence that pest control experts make their recommendations based on the solutions’ efficiency at turning electricity into light.
D
Bug zappers kill many more beneficial insects and fewer harmful insects than do insect-eating birds and insecticide sprays.
This explains why experts recommend birds and insecticides over bug zappers. Though effective in general, bug zappers are less effective than birds and insecticides at targeting and eliminating insects that are pests.
E
Developers of certain new insecticide sprays claim that their products contain no chemicals that are harmful to humans, birds, or pets.
This does not explain why insecticides or birds are favored by pest-control experts over bug zappers. It does not state that insecticides are any safer than bug zappers.
