The mercury has been going up and down this winter, but the temperatures were mainly mild.

"We haven't had too many consecutive days of freezing days, which really what determines a lot of  tick and mosquito populations that will occur within the spring and summer," said Karen Poh, post doctoral scholar in entomology at Penn State.

"Mosquitoes can go in tree holes or even underground in our sewer system to avoid the cold that way."

Meaning the little pests that carry disease could be on the attack and if you are outside you need to be extra careful.

"As if we didn't have enough to worry about. The normal worry for ticks is really important because the rules of nature haven't changed just because we are dealing with COVID as well," said Marten Edwards, professor of biology at Muhlenberg College.

Experts say with warmer temperatures on the horizon people will be wanting to go outside more. That means taking every precaution like wearing long sleeves and long pants, even if you are in the yard gardening.

Also when hiking.

"Stay on the trails, don't go off the trails when you are hiking or anything. Stay away from any standing water," Poh said.

Speaking of standing water, go around your yard to empty any standing water that could help increase the mosquito population.

One last tip, if you are outside, track where you go because symptoms could mimic those of COVID-19 and you want healthcare professionals to have all the pertinent information in case you do get sick.

"People might be more reluctant to get medical help if they're experiencing a fever or unusual rash. It could have been a tick bite. You absolutely need to get medical attention," Edwards said.
