You probably already know that many artificial light fixtures tend to attract bugs. If you’ve never had to clean out a light fixture that has become packed with dead bugs, then you have probably been living under a rock. However, it seems the newer LED lights don’t attract bugs the way the old fluorescent ones did. But wait a second, bugs are attracted to light right, so why aren’t they flocking towards LED lights? It turns out it’s not necessarily just the light bugs are attracted to but rather UV light specifically.
Apparently most bugs rely a great deal on their UV receptors, and their sensitivity to colors in the UV spectrum plays a key role in activities such as foraging, finding a mate, and their ability to navigate properly. Since LED lights emit little to no UV rays, they don’t attract bugs the way other light sources do. Unfortunately, this doesn’t really help when it comes to mosquitos, as these insect pests tend to rely much more on sensing carbon dioxide and water vapor rather than UV light, meaning if you’re human, they’re going to find you with or without light to guide them.
Which types of light fixtures in your home seem to attract the most bugs?
This video takes us to the French town of Chamonix, which is widely regarded as one of the best outdoor playgrounds in the entire world. Renowned for its exceptional skiing and mountain biking, Chamonix is also the launching pad for trekking and climbing expeditions in the Alps, as well as the most popular BASE jumping and wingsuit flying destination on the planet. Here, we’ll see a group of…

The Drug Enforcement Administration’s management of its confidential sources violated guidelines and exposed the agency to potential “fraud, waste, and abuse,” according to a report released by the Justice Department on Thursday.
In total, from fiscal year 2011 to 2015, the DEA shelled out over $9 million to at least 800 deactivated sources, the report found.
Doing so went against official policy with respect to its Confidential Source Program. Sources are typically “deactivated” when they have arrest warrants issued against them or have committed serious offenses.
In another instance of breaking policy, the DEA used a confidential source who had given false testimony under oath in the past. This source “was used by 13 DEA field offices” and was paid close to $500,000, according to the report.
The report also found misconduct related to “Limited Use” sources or “tipsters,” who are supposed to provide information to the DEA of their own accord and without the direction of the agency. The report found that, in multiple instances, the DEA gave explicit directions to tipsters on the information it wanted from them.
Tipsters, despite requiring the least supervision by the agency, were among the highest-paid, with 477 tipsters getting a total of $26.8 million, according to the report. One airline employee who was designated as a Limited Use source was paid over $600,000 in fewer than four years. Another employee was paid over $1 million in five years.
The DEA was also found to have acted against government protocol when it paid Amtrak and Transportation Security Administration (TSA) employees a total of nearly $1.6 million for information during the time period investigated by the report.
Federal regulations currently stipulate that information can be shared between government-owned and operated entities (such as Amtrak, TSA, and the DEA) at no cost. By paying Amtrak and TSA employees for information, the DEA essentially wasted federal funds.
It’s not the first instance of the DEA violated the policy.
In November 2015, the Justice Department released an investigation which found that the DEA had violated policy by paying two Amtrak workers and one TSA worker for information. This audit found that the DEA had actually paid 33 Amtrak workers and 8 TSA workers from 2011 to 2015. The agency continued to pay seven Amtrak employees even after the DOJ released the findings of its 2015 investigation. Payment continued until a new policy was instated last March.
Who the DEA paid wasn’t the only issue. The Justice Department found that the DEA failed to:
- appropriately track sources’ activity or document information
- safeguard sensitive information
- adequately assess the reliability of its sources or the information provided by those sources.
Because of these gaps, the report notes that it is possible that DEA agents may have approached and questioned innocent civilians based on faulty information.
On a number of occasions, the DEA also condoned the use of “sub-sources,” which the report cites as “individuals a source recruits and pays to perform activities or provide information related to the source’s work for the DEA.”
In addition to having questionable reliability, these sub-sources could also have placed major liability on the DEA and DOJ if they acted illegally at any point, according to the report.
The DOJ recommended, among other things, that the DEA work in conjunction with other federal agencies to improve its management of the Confidential Source Program and to tighten regulation of sources and sub-sources.
In a written response to the report, the DEA noted that a new policy it had implemented in July addressed majority of the concerns raised by the investigation.
This is the second report the Justice Department commissioned as part of an audit of the DEA’s Confidential Source Program. The report was initially commissioned in July 2015, but because of “obstacles and delays” the DEA reportedly imposed to prevent review of its program, the Justice Department was not able to release its findings until over a year later.

It is not commonly known that birds and certain flying insects are not solely responsible for plant pollination. The wind also successfully pollinates plants by blowing pollen from plant to plant.
If a particular type of pollen is large, it may weigh too much for it to be carried to another plant via the wind, and it will just fall onto the soil of the parent plant. In these cases, a bird or a flying insect needs to pick up the pollen and transport it to a plant in need of pollination. The chances of a plant becoming pollinated are much greater if an animal is physically transporting the pollen. This is due to the obvious reason that animals always bring the pollen to the proper type of plant while wind blows the pollen in all different directions.
Bees are particularly effective pollinators, as they have the ability to perceive ultraviolet lights reflected off of lines indented into the petals of plants. Bees use this light as a runway that directs them to the proper area to be pollinated. Humans cannot perceive these lines since humans obviously cannot perceive ultraviolet light, but the lines on the petals are visible to humans.
Which type of animal is the most effective pollinator?
