The Yellow Jacket

Yellow Jackets are known for their yellow and black bodies, defined thin waist and elongated wings. The average size of a yellow jacket is half an inch long. They are known to be social wasps that live in colonies of thousands. They are ground nesters and most of their nests can be found under steps, cracks in the sidewalk or in bases of trees. These flying pests will do whatever it takes to defend their nest and will sting repeatedly if they feel threatened.

Some benefits of yellow jackets include the fact that they pollinate flowers and plants, and eat other harmful/annoying insects such as flies or mosquitos. Yellow Jackets are attracted to foods such as meats and sugary items, which is why they tend to frequent picnics and barbecues. If you are having a problem, do not disturb them, call the professionals to remove them properly.

Signs of an Infestation

The best indications of an issue are seeing the yellow jackets themselves or finding their nest. Always be cautious if you see a nest nearby as there could be thousands of yellow jackets and they are known to be aggressive and attack if they feel threatened. They can sting you multiple times as well and for those who are allergic, their stings can also be severe. If you have these pests roaming around the outskirts of your home, contact a pest technician who can safely remove the nest and yellow jackets.

Understanding the Seasons

Weather has a profound effect on pest life cycle. Most pests, rodents and insects breed aggressively during spring and go through periods of hibernation during autumn and winter.

Spring

When the weather slowly begins to heat up, pests start to get more active after having stayed dormant over the colder winter months.

Birds often start to find mates and start building their nests.
Moths which consumer leaves usually become active again.
Flies often emerge from their winter hibernation places and start to breed and spread out.
Squirrels also spend the winter in hibernation. When spring approaches these creatures start looking for a new home. This is usually the time when they make their way into lofts and other spaces.

Summer

Summer is arguably the best season for pests. It is the time when they are in full swing and breed as rapidly as they can. Wasps are one of the most common summer pests followed by flies and rodents. Many a summer picnics and BBQs have been ruined by the ‘home invasion’ of these pests.

Wasps build their nesting grounds and lay their eggs during this time. Although the creatures are not directly harmful, they can be very aggressive and territorial at this time of the year, because they’re at their strongest.
The number of fleas also multiplies. Since pets spend more time outdoors during summer, they are more likely to bring the pests back indoors with them.
Bees are also more active during summer as they go out to gather nectar. Many times, homeowners find a new beehive in their garden and require pest control to take care of it. Because of their sting, bees are more dangerous than some of the other pests and you should call our professional service to get rid of them.
Moths and flies usually start to multiply significantly during summer.
Ants begin to swarm to find new mates and start new colonies during summer.
Cockroaches become very noticeable in the summer, especially in the kitchen and toilets. This is due to the hotter temperatures and stronger smells.
Bedbugs are also very active in the summer.

Autumn

Autumn is the month when things start to get cooler. The number of pests starts to dwindle as they begin to slow down their breeding activities.

Wasps start becoming dozy and docile. You may find them buzzing around occasionally as if they are drunk. This is usually the end-time for their life.
Spiders in particular are more active at this time of the year.
Squirrels will gather their food and start to look for shelter.
The second breeding phase for flies begins. These pests remain active during the season.
Rodents also become more active. Due to the approaching cold, rodents usually find shelter inside homes in the loft or inside walls.

Winter

The coldest months are when pests seek out warmth and shelter. You will find a number of insects especially rodents and lizards make their way inside your home.

Spiders come into our homes to escape the web-destroying frosts.
Rodents move indoors to escape the cold, increasing infestations.
In many cases, homeowners find squirrels nesting in lofts when they go to get their Christmas decorations.
